- Add 'threadsafe' to the feature list shown during build if POSIX
threads are being used.
This is a follow-up to 5adb6000 which added support for building a
thread-safe libcurl with older versions of gcc where atomic is not
available but pthread is.

The idea of `check_library_exists_concat()` is that it detects an
optional component and adds it to the list of libs that we also use in
subsequent component checks. This caused problems when detecting
components with unnecessary dependencies that were not yet built.
CMake offers the `CMAKE_REQUIRED_LIBRARIES` variable to set libs used
for component checks, which we already use in most cases. That left 4
uses of `check_library_exists_concat()`. Only one of these actually
needed the 'concat' feature (ldap/lber).
Delete this function and replace it with standard
`check_library_exists()` and manual management of our `CURL_LIBS`
list we use when linking build targets. And special logic to handle the
ldap/lber case.
(We have a similar function for headers: `check_include_file_concat()`.
It works, but problematic for performance reasons and because it hides
the actual headers required in `check_symbol_exists()` calls.)

- Pass missing parameter for 'lpNumberOfCharsWritten' to WriteConsoleW()
function.
Apparently this parameter was *not* optional on older Windows versions.
Issue observed on Windows XP SP2. Issue not observed on Windows 7 SP1.
So at some point between those two Microsoft changed the behavior.
Prior to this change, on those versions if parameter is NULL then the
function call fails with error ERROR_INVALID_ACCESS.
Regression since af3f4e41.

- Add additional checking for missing and too-short SOCKS5 handshake
messages.
Prior to this change the SOCKS5 test server did not check that all parts
of the handshake were received successfully. If those parts were missing
or too short then the server would access uninitialized memory.
This issue was discovered in CI job 'memory-sanitizer' test results.
Test 2055 was failing due to the SOCKS5 test server not running. It was
not running because either it crashed or memory sanitizer aborted it
during Test 728. Test 728 connects to the SOCKS5 test server on a
redirect but does not send any data on purpose. The test server was not
prepared for that.

Currently, curl allows users to specify absurd request rates that might
be higher than the number of milliseconds in the unit (ex: curl --rate
3600050/h http://localhost:8080 does not error out despite there being
only 3600000ms in a hour).
This change adds a conditional check before the millisecond calculation
making sure that the number is not higher than the numerator (the unit)
If the number is higher, curl errors out with PARAM_NUMBER_TOO_LARGE
Closes#12116
- Remove DEBUGASSERT that an internal handle must not have user
private_data set before calling the user's debug callback.
This is a follow-up to 0dc40b2a. The user can distinguish their easy
handle from an internal easy handle by setting CURLOPT_PRIVATE on their
easy handle. I had wrongly assumed that meant the user couldn't then
set CURLOPT_PRIVATE on an internal handle as well.

This test would show an error message if the output was missing during
the log post-processing step, but the message was not captured by the
test harness and wasn't useful since the normal golden log file
comparison would the problem more clearly.
- configure a 120s idle timeout on our side of the connection

populate_binsettings now returns a negative value on error, instead of a
huge positive value. Both places which call this function have been
updated to handle this change in its contract.
The way populate_binsettings had been used prior to this change the huge
positive values -- due to signed->unsigned conversion of the potentially
negative result of nghttp2_pack_settings_payload which returns negative
values on error -- are not possible. But only because http2.c currently
always provides a large enough output buffer and provides H2 SETTINGS
IVs which pass the verification logic inside nghttp2. If the
verification logic were to change or if http2.c started passing in more
IVs without increasing the output buffer size, the overflow could become
reachable, and libcurl/curl might start leaking memory contents to
servers/proxies...

Fix `HAVE_H_ERRNO_ASSIGNABLE` to not run, only compile its test snippet,
aligning this with autotools. This fixes an error when doing
cross-builds and also actually detects this feature. It affected systems
not allowlisted into this, e.g. SerenityOS.
We used this detection result to enable `HAVE_GETADDRINFO_THREADSAFE`.

Prior to this change the state machine attempted to change the remote
resolve to a local resolve if the hostname was longer than 255
characters. Unfortunately that did not work as intended and caused a
security issue.

- remove these tests as they are currently not reliable in our CI
setups.
curl handles the test cases, but CI sometimes fails on these due to
additional conditions. Rather than mix them in, an additional CI job
will be added in the future that is specific to them.

Syncing this up with CMake.
Source code uses the built-in `OPENSSL_IS_AWSLC` and
`OPENSSL_IS_BORINSSL` macros to detect BoringSSL and AWS-LC. No help is
necessary from the build tools.
The one use of `HAVE_BORINGSSL` in the source turned out to be no longer
necessary for warning-free BoringSSL + Schannel builds. Ref: #1610#2634
autotools detects this anyway for display purposes.
CMake detects this to decide whether to use the BoringSSL-specific
crypto lib with ngtcp2. It detects AWS-LC, but doesn't use the detection
result just yet (planned in #12066).

- Warn that the user's debug callback may be called with the handle
parameter set to an internal handle.
Without this warning the user may assume that the only handles their
debug callback receives are the easy handles on which they set
CURLOPT_DEBUGFUNCTION.
This is a follow-up to f8cee8cc which changed DoH handles to inherit
the debug callback function set in the user's easy handle. As a result
those handles are now passed to the user's debug callback function.
