- Clear data->state.os_errno before transfer.
- Explain the change in behavior in the CURLINFO_OS_ERRNO doc.
- Add to the CURLINFO_OS_ERRNO doc the list of libcurl network-related
errors that may cause the errno to be saved.
data->state.os_errno is saved before libcurl returns a network-related
failure such as connection failure. It is accessible to the user via
CURLINFO_OS_ERRNO so they can get more information about the failure.
Prior to this change it wasn't cleared before transfer, so if a user
retrieved the saved errno it could be from a previous transfer. That is
because an errno is not always saved for network-related errors.

CURLOPT_EGDSOCKET and CURLOPT_RANDOM_FILE are both completely dead
so remove their example sections since the code there is useless.
There is still a way to inject a random file for OpenSSL older than
1.1.0 but it's not what the example showed (and it's not even done
with this option) so we refrain from documenting it here.

Starting now, experimental features should have a set of documentated
requirements of what is needed for the feature to graduate.
This adds requirements to all existing experiments.

Fix wording of comments, and misquotings where `' is markdown parsed
where it shouldn't be, and remove a misspelled preprocessor comment

You can enable it with `-DBUILD_EXAMPLES=ON`.
To match autotools' `make examples` feature.
Windows (static) builds not tested.
Also enable examples in a pair of CI jobs.
Apply related updates to the macOS CI workflow:
- drop unused `CXX` envs.
- drop no longer needed `-Wno-error=undef -Wno-error=conversion` flags.
- pass `-Wno-deprecated-declarations` to GCC too (for `BUILD_EXAMPLES`).
- document why `-Wno-deprecated-declarations` is necessary.

Use a lookup list to set the cipher suites, allowing the
ciphers to be set by either openssl or IANA names.
To keep the binary size of the lookup list down we compress
each entry in the cipher list down to 2 + 6 bytes using the
C preprocessor.

- Call OPENSSL_thread_stop on thread termination (DLL_THREAD_DETACH)
to prevent a memory leak in case OpenSSL is linked statically.
- Warn in libcurl-thread.3 that if OpenSSL is linked statically then it
may require thread cleanup.
OpenSSL may need per-thread cleanup to stop a memory leak. For Windows
and Cygwin if libcurl was built as a DLL then we can do that for the
user by calling OPENSSL_thread_stop on thread termination. However, if
libcurl was built statically then we do not have notification of thread
termination and cannot do that for the user.
Also, there are several other unusual cases where it may be necessary
for the user to call OPENSSL_thread_stop, so in the libcurl-thread
warning I added a link to the OpenSSL documentation.

The rustls backend advertises SSLSUPP_TLS13_CIPHERSUITES, but

Closes#13452
By default the API inhibits empty queries and fragments extracted.
Unless this new flag is set.
This also makes the behavior more consistent: without it set, zero
length queries and fragments are considered not present in the URL. With
the flag set, they are returned as a zero length strings if they were in
fact present in the URL.
This applies when extracting the individual query and fragment
components and for the full URL.

I implemented the IDN functions for macOS and iOS using Unicode
libraries coming with macOS and iOS.
Builds and runs here on macOS 14.2.1. Also verified to load and
run on older macOS version 10.13.
Build requires macOS SDK 13 or equivalent.
Set `-DUSE_APPLE_IDN=ON` CMake option to enable it.
With autotools and other build tools, set these manual options:
```
CPPFLAGS=-DUSE_APPLE_IDN
LIBS=-licucore

Closes#13246
The bounds of the size parameter were not specified, and nor was it
specified how to disable the maximum file size check.
The documentation also incorrectly stated that CURLOPT_MAXFILESIZE
always returns CURLE_OK and that CURLOPT_MAXFILESIZE_LARGE only returns
CURLE_OK or CURLE_UNKNOWN_OPTION.
It also did not mention what the default value is, which is zero. This
commit updates the documentation to make note of all these things.

This time limit the number of files per command to avoid exceeding
limitations of certain OS/shell envs.
Such known env is Windows with the `cmd.exe` shell, which features an
8K command-line length limit to this day.
Allowlisting `UNIX` to have no limit and using a limit of 200 for other
envs to be safe. If there is a way to detect `cmd.exe` and/or we know
which precise envs are sensitive to this, we can tweak these conditions
further.
Even with the low limit, this patch reduces external commands by 200x,
making builds much faster.
