- Insert missing word "from".
- Remove space between function name and "()" so syntax highlighting
can recognise it as a function.
- Avoid "you"/"your" when discussing the reentrancy issues of regular
UNIX signal handlers, because it gives the false impression that
these issues are applicable to g_unix_signal_source_new().

There are a few blocks in Unicode (mainly ideographs)
which default to wide. These blocks are defined in the
header comment of EastAsianWidth.txt.
We have some tests which check that unassigned codepoints
in those blocks get reported as wide, so make sure we handle
this correctly.
When compiling with C++ in MSCV, it defines the __cplusplus macro, but
that's set to an old value and it doesn't represent the current c++
standard version (unless when explicitly requested via `/Zc:__cplusplus`).
So, to enable modern features we should rely on `_MSC_LANG` instead,
which represent the value we care about.
The fix in ad23894c1595482cdc10c17a4070a977e396ca4a only works for
__cplusplus >= 201103L, but older C++ standards are not always less strict,
and still fail to compile the g_atomic_int_compare_and_exchange() and
g_atomic_pointer_compare_and_exchange() macros.
Apply that fix to all C++ standard versions.
Even if this implies using functions that have been added as part of
C++11 specification, this is safe because we wouldn't ever try to use the
`__atomic_...()` APIs if `__ATOMIC_SEQ_CST` is not defined, and that's part
of the very same API.
These functions may be defined as macros with different behaviors in
different c++ versions (as they rely on glib_typeof), so let's ensure
they work and compile everywhere.
When using an older C++ versions, the glib_typeof() macro is never
defined, as the C++ definition depends on __cplusplus >= 201103L, while the C
definition, which would work, depends on !defined(__cplusplus).
Allow old C++ versions to use the C macro definition for glib_typeof().
We've various macros definitions that are depending using C++ features
that may not work in all the standard versions, so recompile the cxx
tests that we have in all the ones we want to support.
Though unlikely to happen, it may happen that newly created file
descriptor take the value 0 (stdin), 1 (stdout) or 2 (stderr) if one
of the standard ones have been dismissed in between. So, it may
confuse the program if it is unaware of this change.
The point of this patch is to avoid a reasign of standard file
descriptors on newly created ones.
Closes issue #16
Those tools are not needed at runtime for typical applications,
distributions typically package them separately.
This makes `meson install --tag runtime` skip installation of those
tools. Omitting `--tag` argument will still install them, as well as
with `--tag bin,bin-devel`.

Do not store jit status for regex unless during initial compilation.
After that, decide whether to use it depending on matching options.
In fact there are some matching options that are incompatible with JIT,
as the PCRE2 docs states:
Setting PCRE2_ANCHORED or PCRE2_ENDANCHORED at match time is not
supported by the just-in-time (JIT) compiler. If it is set, JIT
matching is disabled and the interpretive code in pcre2_match() is
run. Apart from PCRE2_NO_JIT (obviously), the remaining options are
supported for JIT matching.

There's no much point of pre-allocating offsets given that we're doing
this when needed if only have matches to store.
So let's just allocate the spaces for the dummy offset we depend on,
while allocate the others on demand.
While the ovector count would include all the allocated space, we only
care about the actual match values, so avoid wasting allocations and
just use the ones we need to hold the offsets.
In case PCRE2 returns an empty match
This can be easily tested by initializing the initial match data to a
value that is less than the expected match values (e.g. by calling
pcre2_match_data_create (1, NULL)), but we can't do it in our tests
without bigger changes.
We're using int for every size value while PCRE uses uint_32t or
PCRE2_SIZE (size_t in most platforms), let's use the same types to avoid
using different signs.
In case recalc_match_offsets() failed we were just returning, but in
such case, per the documentation we should still set the match_info (if
provided) and free the pcre2 code instance.
So let's just break the loop we're in it, as if we we've no matches set.
This also avoids re-allocating the offsets array and potentially
accessing to unset data.
In case we're getting NO-MATCH "errors", we were still recomputing the
match offsets and taking decisions based on that, that might lead to
undefined behavior.
Avoid this by just returning early a FALSE result (but with no error) in
case there's no result to proceed on.
Fixes: #2741
As per the PCRE2 port we still used to try to map the old GRegex flags
(PCRE1 based) with the new PCRE2 ones, but doing that we were also
mixing flags with enums, leading to unexpected behaviors when trying to
get new line and BSR options out of bigger flags arrays.
So, avoid doing any mapping and store the values as native PCRE2 flags
internally and converting them back only when requested.
This fixes some regressions on newline handling.

For all the memory allocator APIS, document
that they terminate the program on failure.
This was so far only mentioned in the long description,
and in the docs for g_try_malloc(). And with gi-docgen
style docs, the long description is going away.
A file-descriptor was created with the introduction of pidfd_getfd() but
nothing is closing it when the source finalizes. The GChildWatchSource is
the creator and consumer of this FD and therefore responsible for closing
it on finalization.
The pidfd leak was introduced in !2408.
This fixes issues with Builder where anon_inode:[pidfd] exhaust the
available FD limit for the process.
Fixes#2708
man pcre2_pattern_info says that the 3rd argument must
point to uint32_t variable (except for some 2nd argument value),
so correctly use it. Especially using wrong size can cause
unexpected result on big endian.

The prefix for GMarkupParseFlags enumeration members is G_MARKUP; this
means that G_MARKUP_PARSE_FLAGS_NONE gets split into
GLib.MarkupParseFlags.PARSE_FLAGS_NONE by the introspection scanner.
The `/*< nick=none >*/` trigraph attribute is a glib-mkenum thing, and
does not affect the introspection scanner; it would also only affect the
GEnumValue nickname, which is not used by language bindings to resolve
the name of the enumeration member. Plus, GMarkupParseFlags does not
have a corresponding GType anyway.
