mainly for scenarios when pcntl_fork/pcntl_exec are involved so when
the latter is executed, we avoid unwarranted effects with the file
descriptors, instead the socket will be closed on success.

When Valgrind is enabled and not found on the system, default error can
be thrown by PKG_CHECK_MODULES instead of writing a manual error step.
- This uses less redundant variables and has synced CS.
- AS_VAR_IF used instead of raw shell ifs
- Added some basic help descriptions for macro definitions
The m4_normalize is for Autoconf < 2.70 (on 2.70 and later versions a
blank-or-newline separated items can be expanded without using
backslash-newline). The order of headers in configure.ac is left as is
because the first few headers depend on checking other headers (for
those includes the 4th argument).
Updates UCD to Unicode 15.1 (released 2023 Sept). The upcoming
Unicode 16 version will be released roughly on 2024 Sept.
Previously: 0fdffc18, #7502
UCD 15.1 `DerivedNormalizationProps` contains multiple properties in
the same line, which breaks the parser. This also updates the
`ucgendat.php` script to allow 2 or three fields in each line, and to
look for the `Cased` and `Case_Ignorable` properties in either of the
fields to mimic the previous behavior.
Either these are for ParentNode, which are always valid parents that can
hold children. Or these are for ChildNode, which always has a parent
that can have children (by definition).
It was possible to return false without throwing an exception.
This is even wrong in "old DOM" because we expect either a NOT_FOUND_ERR
or NO_MODIFICATION_ALLOWED_ERR according to the documentation.
A side effect of this patch is that it prioritises NOT_FOUND_ERR over
NO_MODIFICATION_ALLOWED_ERR but I think that's fine.
Remove xmlErrMemory from the export section for Windows, this fixes the
build. Even though the original function was renamed [1] it is hidden,
so removing this should be sufficient and not be a BC break.

This also syncs the 1st argument quotes.
The xinclude code from libxml removes the fallback node,
but the fallback node is still reference via $fallback.
The solution is to detach the nodes that are going to be removed in
advance.
Closes GH-14704.
The error handling code isn't entirely right in two places.
One of the code blocks is dead because of an always-false condition, and
another code block is missing the assignment of a NULL pointer.
Getting the exact same behaviour is not entirely possible because you
can't extend the size of a shared memory region after it was made with
the Windows APIs we use, unless we destroy the region and recreate it,
but that has other consequences.
However, it certainly shouldn't crash.
Closes GH-14707.
