docs: fix grammar around needing pass phrase

curl_ws_send.3: call the argument 'fragsize'

websockets: remodeled API to support 63 bit frame sizes
curl_ws_recv() now receives data to fill up the provided buffer, but can
return a partial fragment. The function now also get a pointer to a
curl_ws_frame struct with metadata that also mentions the offset and
total size of the fragment (of which you might be receiving a smaller
piece). This way, large incoming fragments will be "streamed" to the
application. When the curl_ws_frame struct field 'bytesleft' is 0, the
final fragment piece has been delivered.

curl_ws_recv() was also adjusted to work with a buffer size smaller than
the fragment size. (Possibly needless to say as the fragment size can
now be 63 bit large).

curl_ws_send() now supports sending a piece of a fragment, in a
streaming manner, in addition to sending the entire fragment in a single
call if it is small enough. To send a huge fragment, curl_ws_send() can
be used to send it in many small calls by first telling libcurl about
the total expected fragment size, and then send the payload in N number
of separate invokes and libcurl will stream those over the wire.

The struct curl_ws_meta() returns is now called 'curl_ws_frame' and it
has been extended with two new fields: *offset* and *bytesleft*. To help
describe the passed on data chunk when a fragment is delivered in many
smaller pieces.

The documentation has been updated accordingly.

CURLOPT_COOKIEFILE: insist on "" for enable-without-file
The former way that also suggested using a non-existing file to just
enable the cookie engine could lead to developers maybe a bit carelessly
guessing a file name that will not exist, and then in a future due to
circumstances, such a file could be made to exist and then accidentally
libcurl would read cookies not actually meant to.

Makefile.m32: deduplicate build rules [ci skip]
After this patch, we reduce the three copies of most `Makefile.m32`
logic to one. This now resides in `lib/Makefile.m32`. It makes future
updates easier, the code shorter, with a small amount of added
complexity.

`Makefile.m32` reduction:

|                   |  bytes | LOC total |  blank |  comment |  code |
|-------------------|-------:|----------:|-------:|---------:|------:|
| 7.85.0            |  34772 |      1337 |     79 |      192 |  1066 |
| before this patch |  17601 |       625 |     62 |      106 |   457 |
| after this patch  |  11680 |       392 |     52 |      104 |   236 |

Details:

- Change rules to create objects for the `v*` subdirs in the `lib` dir.
  This allows to use a shared compile rule and assumes that filenames
  are not (and will not be) colliding across these directories.
  `Makefile.m32` now also stores a list of these subdirs. They are
  changing rarely though.

- Sync as much as possible between the three `Makefile.m32` scripts'
  rules and their source/target sections.

- After this patch `CPPFLAGS` are all applied to the `src` sources once
  again. This matches the behaviour of cmake/autotools. Only zlib ones
  are actually required there.

- Use `.rc` names from `Makefile.inc` instead of keeping a duplicate.

- Change examples to link `libcurl.dll` by default. This makes building
  trivial, even as a cross-build:
    `CC=x86_64-w64-mingw32-gcc make -f Makefile.m32`
  To run them, you need to move/copy or add-to-path `libcurl.dll`.
  You can select static mode via `CFG=-static`.

- List more of the `Makefile.m32` config variables.

- Drop `.rc` support from examples. It made it fragile without much
  benefit.

- Include a necessary system lib for the `externalsocket.c` example.

- Exclude unnecessary systems libs when building in `-dyn` mode.

Makefile.m32: major rework [ci skip]
This patch overhauls `Makefile.m32` scripts, fixing a list of quirks,
making its behaviour and customization envvars align better with other
build systems, aiming for less code, that is easier to read, use and
maintain.

Details:
- Rename customization envvars:
  `CURL_CC` -> `CC`
  `CURL_RC` -> `RC`
  `CURL_AR` -> `AR`
  `CURL_LDFLAG_EXTRAS_DLL` -> `CURL_LDFLAGS_LIB`
  `CURL_LDFLAG_EXTRAS_EXE` -> `CURL_LDFLAGS_BIN`
- Drop `CURL_STRIP` and `CURL_RANLIB`. These tools are no longer used.
- Accept `CFLAGS`, `CPPFLAGS`, `RCFLAGS`, `LDFLAGS` and `LIBS` envvars.
- Drop `CURL_CFLAG_EXTRAS`, `CURL_LDFLAG_EXTRAS`, `CURL_RCFLAG_EXTRAS` in
  favor of the above.
- Do not automatically enable `zlib` with `libssh2`. `zlib` is optional
  with `libssh2`.
- Omit unnecessary `CPPFLAGS` options when building `curl.exe` and
  examples.
- Drop support for deprecated `-winssl` `CFG` option. Use `-schannel`
  instead.
- Avoid late evaluation where not necessary (`=` -> `:=`).
- Drop support for `CURL_DLL_A_SUFFIX` to override the implib suffix.
  Instead, use the standard naming scheme by default: `libcurl.dll.a`.
  The toolchain recognizes the name, and selects it automatically when
  asking for a `-shared` vs. `-static` build.
- Stop applying `strip` to `libcurl.a`. Follow-up from
  16a58e9f93. There was no debug info to
  strip since then.
- Stop setting `-O3`, `-W`, `-Wall` options. You can add these to
  `CFLAGS` as desired.
- Always enable `-DCURL_DISABLE_OPENSSL_AUTO_LOAD_CONFIG` with OpenSSL,
  to avoid that vulnerability on Windows.
- Add `-lbrotlicommon` to `LIBS` when using `brotli`.
- Do not enable `-nghttp3` without `-ngtcp2`.
- `-ssh2` and `-rtmp` options no longer try to auto-select a TLS-backend.
  You need to set the backend explicitly. This scales better and avoids
  issues with certain combinations (e.g. `libssh2` + `wolfssl` with no
  `schannel`).
- Default to OpenSSL TLS-backend with `ngtcp2`. Possible to override via
  `NGTCP2_LIBS`.
- Old, alternate method of enabling components (e.g. `SSH2=1`) no longer
  supported.
- Delete `SPNEGO` references. They were no-ops.
- Drop support for Win9x environments.
- Allow setting `OPENSSL_LIBS` independently from `OPENSSL_LIBPATH`.
- Support autotools/CMake `libssh2` builds by default.
- Respect `CURL_DLL_SUFFIX` in `-dyn` mode when building `curl.exe` and
  examples.
- Assume standard directory layout with `LIBCARES_PATH`. (Instead of the
  long gone embedded one.)
- Stop static linking with c-ares by default. Add
  `CPPFLAGS=-DCARES_STATICLIB` to enable it.
- Reorganize internal layout to avoid redundancy and emit clean diffs
  between src/lib and example make files.
- Delete unused variables.
- Code cleanups/rework.
- Comment and indentation fixes.

Makefile.m32: delete legacy component bits [ci skip]
- Drop auto-detection of OpenSSL 1.0.2 and earlier. Now always defaulting
  to OpenSSL 1.1.0 and later, LibreSSL and BoringSSL.

- Drop `Invalid path to OpenSSL package` detection. OpenSSL has been
  using a standard file layout since 1.1.0, so this seems unnecessary
  now.

- Drop special logic to enable Novell LDAP SDK support.

- Drop special logic to enable OpenLDAP LDAP SDK support. This seems
  to be distinct from native OpenLDAP, with support implemented inside
  `lib/ldap.c` (vs. `lib/openldap.c`) back when the latter did not exist
  yet in curl.

- Add `-lwldap32` only if there is no other LDAP library (either native
  OpenLDAP, or SDKs above) present.

- Update `doc/INSTALL.md` accordingly.

After this patch, it's necessary to make configration changes when using
OpenSSL 1.0.2 or earlier, or the two LDAP SDKs.

OpenSSL 1.0.2 and earlier:
```
export OPENSSL_INCLUDE = <path-to-openssl>/outinc
export OPENSSL_LIBPATH = <path-to-openssl>/out
export OPENSSL_LIBS = -lssl32 -leay32 -lgdi32
```

Novell LDAP SDK, previously enabled via `USE_LDAP_NOVELL=1`:
```
export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/inc -DCURL_HAS_NOVELL_LDAPSDK
export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib/mscvc -lldapsdk -lldapssl -lldapx
```

OpenLDAP LDAP SDK, previously enabled via `USE_LDAP_OPENLDAP=1`:
```
export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/include -DCURL_HAS_OPENLDAP_LDAPSDK
export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib -lldap -llber
```

I haven't tested these scenarios, and in general we recommend using
a recent OpenSSL release. Also, WinLDAP (the Windows default) and
OpenLDAP (via `-DUSE_OPENLDAP`) are the LDAP options actively worked on
in curl.

Makefile.m32: cleanups and fixes [ci skip]
- Add `-lcrypt32` once, and add it always for simplicity.
- Delete broken link and reference to the pre-Vista WinIDN add-on.
  MS no longer distribute it.
- Delete related `WINIDN_PATH` option. IDN is a system lib since Vista.
- Sync `LIBCARES_PATH` default with the rest of dependencies.
- Delete version numbers from dependency path defaults.
- `libgsasl` package is now called `gsasl`.
- Delete `libexpat` and `libxml2` references. No longer used by curl.
- Delete `Edit the path below...` comments. We recommend to predefine
  those envvars instead.
- `libcares.a` is not an internal dependency anymore. Stop using it as
  such.
- `windres` `--include-dir` -> `-I`, `-F` -> `--target=` for readability.
- Delete `STRIP`, `CURL_STRIP`, `AR` references from `src/Makefile.m32`.
  They were never used.
- Stop to `clean` some objects twice in `src/Makefile.m32`.
- Delete cvs-specific leftovers.
- Finish resource support in examples make file.
- Delete `-I<root>/lib` from examples make file.
- Fix copyright start year in examples make file.
- Delete duplicate `ftpuploadresume` input in examples make file.
- Sync OpenSSL lib order, `SYNC` support, `PROOT` use, dependency path
  defaults, variables names and other internal bits between the three
  make files.
- `lib/Makefile.m32` accepted custom options via `DLL_LIBS` envvar. This
  was lib-specific and possibly accidental. Use `CURL_LDFLAG_EXTRAS_DLL`
  envvar for the same effect.
- Fix linking `curl.exe` and examples to wrong static libs with
  auto-detected OpenSSL 1.0.2 or earlier.
- Add `-lgdi32` for OpenSSL 1.0.2 and earlier only.
- Add link to Novell LDAP SDK and use a relative default path. Latest
  version is from 2016, linked to an outdated OpenSSL 1.0.1.
- Whitespace and comment cleanups.

TODO in a next commit:

Delete built-in detection/logic for OpenSSL 1.0.2 and earlier, the Novell
LDAP SDK and the other LDAP SDK (which is _not_ OpenLDAP). Write up the
necessary custom envvars to configure them.

lib: sanitize conditional exclusion around MIME
The introduction of CURL_DISABLE_MIME came with some additional bugs:
- Disabled MIME is compiled-in anyway if SMTP and/or IMAP is enabled.
- CURLOPT_MIMEPOST, CURLOPT_MIME_OPTIONS and CURLOPT_HTTPHEADER are
  conditioned on HTTP, although also needed for SMTP and IMAP MIME mail
  uploads.

In addition, the CURLOPT_HTTPHEADER and --header documentation does not
mention their use for MIME mail.

This commit fixes the problems above.

- remove two fields from the URL handle struct
- reduce copies and allocs
- use dynbuf buffers more instead of custom malloc + copies
- uses dynbuf to build the host name in reduces serial alloc+free within
  the same function.
- move dedotdotify into urlapi.c and make it static, not strdup the input
  and optimize it by checking for . and / before using strncmp
- remove a few strlen() calls
- add Curl_dyn_setlen() that can "trim" an existing dynbuf

NPN: remove support for and use of
Next Protocol Negotiation is a TLS extension that was created and used
for agreeing to use the SPDY protocol (the precursor to HTTP/2) for
HTTPS. In the early days of HTTP/2, before the spec was finalized and
shipped, the protocol could be enabled using this extension with some
servers.

curl supports the NPN extension with some TLS backends since then, with
a command line option `--npn` and in libcurl with
`CURLOPT_SSL_ENABLE_NPN`.

HTTP/2 proper is made to use the ALPN (Application-Layer Protocol
Negotiation) extension and the NPN extension has no purposes
anymore. The HTTP/2 spec was published in May 2015.

Today, use of NPN in the wild should be extremely rare and most likely
totally extinct. Chrome removed NPN support in Chrome 51, shipped in
June 2016. Removed in Firefox 53, April 2017.

CURLOPT_WILDCARDMATCH.3: Fix backslash escaping under single quotes
Lintian (on Debian) has been complaining about this for a while but
 I didn't bother initially as the groff parser that we use is not
 affected by this.

 But I have now noticed that the online manpage is affected by it:
 https://curl.se/libcurl/c/CURLOPT_WILDCARDMATCH.html

 (I'm using double quotes for quoting-only down below)

 The section that should be parsed as "'\'" ends up being parsed as
 "'´".

 This is due to roffit not parsing "'\\'" correctly, which is fine
 as the "correct" way of writing "'\'" is "'\e'" instead.

 Note that this fix is not enough to fix the online manpage at
 curl's website, as roffit seems to parse it wrongly either way.

 My intent is to at least fix the manpage so that roffit can
 be changed to parse "'\e'" correctly (although I suggest making
 roffit parse both ways correctly, since that's what groff does).

Makefile.m32: allow -nghttp3/-ngtcp2 without -ssl [ci skip]
Before this patch `-nghttp3`/`-ngtcp2` had an effect only when `-ssl`
was also enabled. `-ssl` meaning OpenSSL (and its forks). After
8a13be227e nghttp3/ngtcp2 can also be
used together with wolfSSL. This patch adds the ability to enable
`-nghttp3`/`-ngtcp2` independently from `-ssl` (OpenSSL), allowing to
use it with wolfSSL or other, future TLS backends.

Before this patch, it was fine to enable `-nghttp3`/`-ngtcp2`
unconditionally. After this patch, this is no longer the case, and now
it's the user's responsibility to enable `-nghttp3`/`-ngtcp2` only
together with a compatible TLS backend.

When using a TLS backend other than OpenSSL, the TLS-specific ngtcp2
library must be configured manually, e.g.:
  `export CURL_LDFLAG_EXTRAS=-lngtcp2_crypto_wolfssl`

(or via `NGTCP2_LIBS`)

92179353e5 cmdline-opts/gen.pl: improve performance
On some systems, the gen.pl script takes nearly two minutes for the
generation of the main-page, which is a completely unacceptable time.

The slow performance has two causes:
1. Use of a regex locale operator
2. Useless invokations of loops

The commit addresses the first issue by replacing the "\W" wiht
[^a-zA-Z0-9_], which is, according to regex101.com, functionally
equivalent to the previous operation, except that it is obviously
limited to ASCII only, which is fine, as the curl project is
English-only anyway.

The second issue is being addressed by only running the loop if the line
contains a "--" in it. The loop may be completeley removed in the
future.

Makefile.m32: add CURL_RC and CURL_STRIP variables [ci skip]
They allow to override the hardcoded values for the `windres` and `strip`
tools, complementing the existing set of `CURL_{CC,AR,RANLIB}` variables.

`CURL_RC` comes handy when using LLVM tools with `CROSSPREFIX=llvm-` and
`CURL_CC=clang` set on current latest debian:unstable or earlier, where
`llvm-windres` is missing, and a `CURL_RC=<triplet>-windres` fixes it.
Hopefully this will be fixed in the llvm package. FWIW `llvm-windres`
does exist in Homebrew llvm, MSYS2 llvm and llvm-mingw.
