cabcf403ed docs/opts: Mention Schannel client cert type is P12
Schannel backend code behaves same as Secure Transport, it expects a P12
certificate file or the name of a certificate already in the user's OS
key store. Also, both backends ignore CURLOPT_SSLKEY (tool: --key)
because they expect the private key to already be available from the
keystore or P12 certificate.

rustls: add CURLOPT_CAINFO_BLOB support
Add support for `CURLOPT_CAINFO_BLOB` `CURLOPT_PROXY_CAINFO_BLOB` to the
rustls TLS backend. Multiple certificates in a single PEM string are
supported just like OpenSSL does with this option.

This is compatible at least with rustls-ffi 0.8+ which is our new
minimum version anyway.

I was able to build and run this on Windows, pulling trusted certs from
the system and then add them to rustls by setting
`CURLOPT_CAINFO_BLOB`. Handy!

- Use dynamic memory for ldap_init_fd() URL rather than a
  stack-allocated buffer.
- Never chase referrals: supporting it would require additional parallel
  connections and alternate authentication credentials.
- Do not wait 1 microsecond while polling/reading query response data.

mime: use percent-escaping for multipart form field and file names
Until now, form field and file names where escaped using the
backslash-escaping algorithm defined for multipart mails. This commit
replaces this with the percent-escaping method for URLs.

As this may introduce incompatibilities with server-side applications, a
new libcurl option CURLOPT_MIME_OPTIONS with bitmask
CURLMIMEOPT_FORMESCAPE is introduced to revert to legacy use of
backslash-escaping. This is controlled by new cli tool option
--form-escape.

New tests and documentation are provided for this feature.

CURLOPT_IPRESOLVE: preventing wrong IP version from being used
In some situations, it was possible that a transfer was setup to
use an specific IP version, but due do DNS caching or connection
reuse, it ended up using a different IP version from requested.

This commit changes the effect of CURLOPT_IPRESOLVE from simply
restricting address resolution to preventing the wrong connection
type being used, when choosing a connection from the pool, and
to restricting what addresses could be used when establishing
a new connection.

It is important that all addresses versions are resolved, even if
not used in that transfer in particular, because the result is
cached, and could be useful for a different transfer with a
different CURLOPT_IPRESOLVE setting.

http: limit the initial send amount to used upload buffer size
Previously this logic would cap the send to CURL_MAX_WRITE_SIZE bytes,
but for the situations where a larger upload buffer has been set, this
function can benefit from sending more bytes. With default size used,
this does the same as before.

Also changed the storage of the size to an 'unsigned int' as it is not
allowed to be set larger than 2M.

Also added cautions to the man pages about changing buffer sizes in
run-time.

77fc3859b2 SSL: support in-memory CA certs for some backends
- New options CURLOPT_CAINFO_BLOB and CURLOPT_PROXY_CAINFO_BLOB to
  specify in-memory PEM certificates for OpenSSL, Schannel (Windows)
  and Secure Transport (Apple) SSL backends.

Prior to this change PEM certificates could only be imported from a file
and not from memory.

54e7475016 schannel: Disable auto credentials; add an option to enable it
- Disable auto credentials by default. This is a breaking change
  for clients that are using it, wittingly or not.

- New libcurl ssl option value CURLSSLOPT_AUTO_CLIENT_CERT tells libcurl
  to automatically locate and use a client certificate for
  authentication, when requested by the server.

- New curl tool options --ssl-auto-client-cert and
  --proxy-ssl-auto-client-cert map to CURLSSLOPT_AUTO_CLIENT_CERT.

This option is only supported for Schannel (the native Windows SSL
library). Prior to this change Schannel would, with no notification to
the client, attempt to locate a client certificate and send it to the
server, when requested by the server. Since the server can request any
certificate that supports client authentication in the OS certificate
store it could be a privacy violation and unexpected.

53022e1893 doh: add options to disable ssl verification
- New libcurl options CURLOPT_DOH_SSL_VERIFYHOST,
  CURLOPT_DOH_SSL_VERIFYPEER and CURLOPT_DOH_SSL_VERIFYSTATUS do the
  same as their respective counterparts.

- New curl tool options --doh-insecure and --doh-cert-status do the same
  as their respective counterparts.

Prior to this change DOH SSL certificate verification settings for
verifyhost and verifypeer were supposed to be inherited respectively
from CURLOPT_SSL_VERIFYHOST and CURLOPT_SSL_VERIFYPEER, but due to a bug
were not. As a result DOH verification remained at the default, ie
enabled, and it was not possible to disable. This commit changes
behavior so that the DOH verification settings are independent and not
inherited.
