PCRE2 10.43 has now introduced support for variable-length lookbehind,
so these tests now fail if GLib is built against PCRE2 10.43 or higher.
See
e8db6fa713/ChangeLog (L94).
Rather than making the tests conditional on the version of PCRE2 in use,
just remove them. They are mostly testing the PCRE2 code rather than
any code in GLib, so don’t have much value.
This should fix CI runs on msys2-mingw32, which updated to PCRE2 10.43 2
days ago.

The `g_content_type_guess_for_tree` function segfaults currently when
processing filenames that are not valid unicode strings. Let's use the
`g_filename_to_utf8` and `g_utf8_make_valid` functions before other
processing to prevent that.

(cherry picked from commit 41af42717531a2af6dfd7a4f7b5c5fc228e85f0d)
For the same reasons as in commit 71061fdcb33b8c26f5f8467c, but in this
case we can’t downgrade the version of Meson on the CI runner, so just
tell it to shut up instead.

Symptom:
20 0x00007ffff756337b in gtk_widget_size_allocate_with_baseline (widget=0xd7a0c0 [DirectWindow], allocation=, baseline=) at
gdb.error: value has been optimized out
This is just the result of running `black $(git ls-files '*.py')`.
For some reason, the `sh-and-py-check` CI job didn’t run on merge
request !3751, so this non-standard formatting slipped through onto
`main`.

This fixes a stack overflow reported by a user who had both the
definition of text/javascript from shared-mime-info 2.3 and the
definition of text/javascript from shared-mime-info 2.4 installed at the
same time. In 2.3, text/javascript is a subtype of
application/ecmascript, but in 2.4 application/ecmascript is a subtype
of text/javascript. Having both at the same time resulted in circular
inheritance.
The new logic keeps a list of all parents that have already been
checked, which is more comprehensive than the old workaround that was
implemented in commit 38869ece2 ("xdgmime: Prevent infinite loops from
badly-formed MIME registrations").

Depending on the operating system, /bin/sh might either be bash (for
example on Fedora or Arch) or dash (for example on Debian or Ubuntu)
or some other POSIX shell.
When bash is asked to run a simple command with no shell keywords or
metacharacters, like this one, it replaces itself with the program
via execve(), but dash does not have that optimization and treats it
like any other program invocation in a larger script: it will fork,
exec the program in the child, and wait for the child in the parent.
This seems like it conflicts with sleep_and_kill() assuming that it can
use the subprocess's process ID as the sleep(1) process ID. Specifically,
if it sends SIGKILL, it will go to the sh(1) process and not the sleep(1)
child, which could result in the sh(1) process being terminated and
its sleep(1) child being leaked.
To get the bash-like behaviour portably, explicitly use the exec builtin
to instruct the shell to replace itself with sleep(1), so that the
process ID previously used for the shell becomes the process ID of the
sleep process.
This appears to resolve an intermittent hang and test timeout on Debian
machines (especially slower ones), although I'm not 100% clear on the
mechanics of how it happens.

The PTRACE_O_EXITKILL symbol in sys/ptrace.h is an enum member, not
a macro. The #ifdef check added to the GSubprocess test-case in
272ec5dbca8ec957ced2cdca45bde69f47fb4df9 will not detect it.
Use cc.has_header_symbol() to properly detect it. According to the
documentation: "Symbols here include function, variable, #define,
type definition, etc.".

When calling `g_file_set_contents_full()` without
`G_FILE_SET_CONTENTS_CONSISTENT`, the file is written by opening it,
`write()`ing to it, then closing it.
This is fine as long as the file is not longer than the new content you
want to set its contents to. If it is, the last bit of the old content
remains, because `g_file_set_contents_full()` was missing an
`ftruncate()` call.
Fix that, and change the tests to catch truncation failures in future.

(Backport 2.78: Unmark new translatable string as translatable, to avoid
adding need for translations.)
Commit f6c40b1d fixed libelf detection on FreeBSD (where the library has
no pkg-config file and needs to be found via `find_library()`), but
broke `-Dlibelf=disabled` on Linux, as `get_option('libelf')` was no
longer checked.
