Since data can be held in connection filter buffers when sending gives
EAGAIN, add methods to query this and perform flushing of those buffers.
The transfer loop will continue sending until all upload data is
processed and the connection is flushed.
- add `CF_QUERY_SEND_PENDING` to query filters
- add `CF_CTRL_DATA_SEND_FLUSH` to flush filters
- change `Curl_req_want_send()` to query the connection
if it needs flushing
- use `Curl_req_want_send()` to determine the POLLOUT
in the PERFORMING multi state
- implement flush handling in the HTTP/2 connection filter
Closes#14271
Adds a `bool eos` flag to send methods to indicate that the data
is the last chunk the invovled transfer wants to send to the server.
This will help protocol filters like HTTP/2 and 3 to forward the
stream's EOF flag and also allow to EAGAIN such calls when buffers
are not yet fully flushed.

Replace Curl_resolv_unlock() with Curl_resolv_unlink():
-replace inuse member with refcount in Curl_dns_entry
- pass Curl_dns_entry ** to unlink, so it gets always cleared
- solve potential (but unlikley) UAF in FTP's handling of looked up
Curl_dns_entry. Esp. do not use addr information after unlinking an entry.
In reality, the unlink will not free memory, as the dns entry is still
referenced by the hostcache. But this is not safe and relying on no other
code pruning the cache in the meantime.
- pass permanent flag when adding a dns entry instead of fixing timestamp
afterwards.
url.c: fold several static *resolve_* functions into one.

- in DEBUGBUILD, all specifying if true random numbers

Turns out that MAC != OSX, despite what these names otherwise mean and
what's suggested by source code comments. "MAC" in fact means Darwin
(aka Apple), not macOS. "OSX" means macOS.
GitHub bumped the macos-14 runner default to Xcode 15.4, hitting the
llvm@15 incompatibility bug by default. Meaning the previous workaround
for the SDK bug is necessary.
This patch extend the workaround to not apply to mobile OS variants.

connections being shutdown would register sockets for events, but then
never remove these sockets again. Nor would the shutdown effectively
been performed.
- If a socket event involves a transfer, check if that is the
connection cache internal handle and run its multi_perform()
instead (the internal handle is used for all shutdowns).
- When a timer triggers for a transfer, check also if it is
about the connection cache internal handle.
- During processing shutdowns in the connection cache, assess
the shutdown timeouts. Register a Curl_expire() of the lowest
value for the cache's internal handle.

If OpenSSL 1.x is used, and it is configured with md4 disabled,
OPENSSL_NO_MD4 is defined in opensslconf.h, but this header was not
included before checking for this define.
Later in md4.c, openssl/md4.h is included, and it includes that header
indirectly, leading to inconsistency within md4.c.
Since the md4.h branch was taken, wincrypt.h (or others) is not
included, and later below the USE_WIN32_CRYPTO branch is taken, but the
types are not defined.

When removing an easy handle that had DoH sub-easy handles going, those
were not removed from the multi handle. Their memory was reclaimed on
curl_easy_cleanup() of the owning handle, but multi still had them in
their list.
Add `Curl_doh_close()` and `Curl_doh_cleanup()` as common point for
handling the DoH resource management. Use the `multi` present in the doh
handles (if so), for removal, as the `data->multi` might already have
been NULLed at this time.

Currently we're waiting for sendbuf_len_in_flight to hit zero before
resuming upload which means we're blocking and waiting for _all_ acks to
arrive before sending more data. This causes significant delays especially
when ack delay is used on the server side.
The fix addresses several issues in h3 over ngtcp2:
- On ack we now call nghttp3_conn_resume_stream() when we have more
data to send.
- upload_left was incorrectly computed on CF_CTRL_DATA_DONE_SEND as
we need to subtract the ammount of data we have in flight.
- Remove upload_blocked_len as we Curl_bufq_write call will do the
right thing when called from cf_ngtcp2_send.

Bug: #14176Closes#14179
In specific builds configs, cmake failed to build test `unit1600`,
due missing an OpenSSL (or wolfSSL) header.
The test code relies on `lib/curl_ntlm_core.h`, which in turn included
TLS library headers. But, dependency header directories are not setup
in cmake for tests, because they should not normally be needed.
The issue was hidden in most builds because TLS headers are usually
found under the system prefix. One counterexample is macOS + Homebrew
LibreSSL builds, where OpenSSL is purposefully unlinked from there to
avoid a mixup with LibreSSL that resides under its own prefix. It was
also hidden in autotools, possibly because it sets up header directories
globally, tests included.
The actual bug however is that `lib/curl_ntlm_core.h` should not include
TLS headers. None of its internal users need it, and `curl_ntlm_core.c`
included them already directly.
Fix it by deleting the TLS header includes from this internal header.
Fixes:
```

Fix `-Wpointer-bool-conversion` warnings with the method suggested by
both Apple clang and mainline llvm. This was already tried and dropped
in #1705 (in year 2017), but the issue reported there no longer
replicates.
Verified with Apple clang 14, llvm 15, llvm 18 and gcc 11, 14 that the
generated objects are bit by bit identical before and after this patch.
Also:
- stop silencing `-Wtautological-pointer-compare`. This warning don't
seem to be appearing anymore (with or without this patch), at least
with the tested compilers and SDKs (clang 13.1.6-16.0.0beta, llvm 15,
18, gcc 11, 14) and minimum macOS target of 10.8. Older targets fail
to build curl with SecureTransport.
- silence `-Wunreachable-code` for clang only. Previously I applied it
also to GCC, by mistake.
