Compile with the preprocessor definitions necessary for the `arc4random`
family so it's available even when compiler extensions are not enabled.
Similar things are done in cmbzip2, cmcurl, cmlibarchive, cmliblizma and
cmlibuv.
This issue surfaced on a nightly bot after glibc 2.36 added arc4random
functions. cmlibarchive defines the necessary macro, but also relies on
`HAVE_ARC4RANDOM_BUF`. cmlibarchive's check with the necessary macro
defined was skipped due to cmexpat running the same check before, but
without the macros, and it being cached.
This extends commit c7c3e39e4f (Utilities: Activate POSIX APIs even
without compiler extensions, 2022-06-02, v3.24.0-rc1~34^2) to cover our
build of expat too.

Curl 7.85.0 introduced support for TLS 1.3 support with schannel.
We've observed connection failures in some cases, so disable the
support pending further investigation.

Configuring with `--log-level=VERBOSE` a user can see an output of
`sphinx-build` at build time.
The other way is to have `VERBOSE` envvar set at configure time.
And finally one can set `CMAKE_VERBOSE_MAKEFILE` CMake cache variable.
The stderr has the potential to count warnings from system header
files, which are very platform-specific and not reliable, and they
are simply a count of all the warnings that were emitted on stdout,
which we already have. Remove stderr and only look at stdout.

The `remove_filename` and `replace_extension` methods compute an offset
between the whole path in a `std::string` and a part of a path in a
`std::string_view`. This is done by subtracting their `.data()`
pointers. However, C++17 adds a non-const `.data()` through which
modification of the string is allowed. This means the copy-on-write
implementation used by the pre-C++11 std::string GNU ABI must reallocate
if the string has been copied. Our subtraction then computes an offset
between two different allocations, which is undefined behavior.
The workaround in commit b3ca4f9ad1 (cm/filesystem: Work around crash
when compiled for CYGWIN/MSYS runtime, 2021-04-22, v3.21.0-rc1~271^2~2)
avoided the problem by calling the non-const `.data()` to reallocate
before constructing the `string_view`. Instead, explicitly call the
const `.data()` method on the string, which does not reallocate.

The `SafeString` and `ErrorString` classes are deprecated and will be
removed in Docutils 0.21 or later. They help avoid encoding errors
during exception handling in Python <= 2.7, but these days we always
use Python 3 to build the documentation, at least during development,
when error cases are most likely to occur.

The QtHelp Sphinx generation code contains two links to Sphinx issues
that used old, dead BitBucket URLs. Those issues were migrated to
GitHub, so the dead links can be replaced with working ones.
