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
If a deprecated property only gets set because it is G_PARAM_CONSTRUCT
or G_PARAM_CONSTRUCT_ONLY, then there is nothing for the library user
to fix, and we should not emit a deprecation warning.

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.

Sync with changes from GTK:
- Set a git config to work around security
improvements in recent git.
- Only fetch the two branches we want to compare
for the style check.
- Use the existing git merge-base command to find
their common ancestor.
The `(transfer none)` behaviour for `parameter_type` and `state_type`
parameters is implicit with the `const` attribute, but was incorrectly
determined to be `(transfer full)` in the GIR.
Add explicit `(transfer none)` annotations for these two parameters.
