This should maintain equivalent functionality, apart from that now you
have to pass `--force-fallback-for libpcre` to `meson configure` in
order to use the subproject; rather than specifying
`-Dinternal_pcre=true` to use the internal copy.
This also fixes#642, as the wrapdb copy of libpcre is version 8.37.

Fedora 29 is no longer available, and I need to rebuild these images so
libpcre is pre-downloaded as a subproject.
Update them to Fedora 31, which is what we use in `fedora.Dockerfile`.
This should allow some blobs to be shared in the container repository.
This isn’t the latest Fedora release, but I don’t want to go through the
hassle of updating all the CI images to F33 right now in addition to
updating the subproject caches.
`python-unversioned-command` is needed because the Android NDK calls
`python` without a version number. F29 must have installed this already.
The Android NDK setup appears to be OK with Python 3.

This is basically a contrived test to trigger the `bytes->user_data !=
bytes->data` condition (and none of the earlier short-circuiting
conditions in that statement) in `try_steal_and_unref()`. This gives
100% line and branch coverage for `gbytes.c`.

WebKit wants these private key properties to be readable in order to
implement a deserialization function. Currently they are read-only
because at the time GTlsCertificate was originally designed, the plan
was to support PKCS#11-backed private keys: private keys that are stored
on a smartcard, where the private key is completely unreadable. The
design goal was to support both memory-backed and smartcard-backed
private keys with the same GTlsCertificate API, abstracting away the
implementation differences such that code using GTlsCertificate doesn't
need to know the difference.
The original PKCS#11 implementation was never fully baked and at some
point in the past I deleted it all. It has since been replaced with a
new implementation, including a GTlsCertificate:private-key-pkcs11-uri
property, which is readable. So our current API already exposes the
differences between normal private keys and PKCS#11-backed private keys.
The point of making the private-key and private-key-pem properties
write-only was to avoid exposing this difference.
Do we have to make this API function readable? No, because WebKit could
be just as well served if we were to expose serialize and deserialize
functions instead. But WebKit needs to support serializing and
deserializing the non-private portion of GTlsCertificate with older
versions of GLib anyway, so we can do whatever is nicest for GLib. And I
think making this property readable is nicest, since the original design
reason for it to not be readable is now obsolete. The disadvantage to
this approach is that it's now possible for an application to read the
private-key or private-key-pem property, receive NULL, and think "this
certificate must not have a private key," which would be incorrect if
the private-key-pkcs11-uri property is set. That seems like a minor
risk, but it should be documented.
A reader might think "how would a process terminate without an exit
status?", or equivalently, "what harm would it do if I assume every
termination has an exit status?" without this reminder that termination
with a signal is also reasonably common.

On Unix platforms, wait() and friends yield an integer that encodes
how the process exited. Confusingly, this is usually not the same as
the integer passed to exit() or returned from main(): conceptually it's
an integer encoding of this tagged union:
enum { EXITED, SIGNALLED, ... } tag;
union {
int exit_status; /* if EXITED */
struct {
int terminating_signal;
bool core_dumped;
} terminating_signal; /* if SIGNALLED */
...
} detail;
Meanwhile, on Windows, wait statuses and exit statuses are
interchangeable.
I find that it's clearer what is going on if we are consistent about
referring to the result of wait() as a "wait status", and the value
passed to exit() as an "exit status".
GSubprocess already gets this right: g_subprocess_get_status() returns
the wait status, while g_subprocess_get_exit_status() genuinely returns
the exit status. However, the GSpawn family of APIs has tended to
conflate the two.
Confusingly, g_spawn_check_exit_status() has always checked a wait
status, and it would not be correct to pass an exit status to it; so
let's deprecate it in favour of g_spawn_check_wait_status(), which
does the same thing that g_spawn_check_exit_status() always did.
Code that needs backwards-compatibility with older GLib can use:
#if !GLIB_CHECK_VERSION(2, 69, 0)
#define g_spawn_check_wait_status(x) (g_spawn_check_exit_status (x))
#endif

Confusingly, g_spawn_check_exit_status() takes a wait status, not an
exit status, so passing g_subprocess_get_exit_status() to it is
incorrect (although both encodings happen to use 0 to encode success
and a nonzero value to encode failure, so in practice this probably
had the desired effect).

If `g_file_monitor_source_dispatch()` drops the last reference to its
`GLocalFileMonitor`, a deadlock will occur, because disposing the
`GLocalFileMonitor` causes synchronous disposal of the
`GFileMonitorSource`, and hence an attempt to re-lock the already-locked
mutex in the `GFileMonitorSource`.
Fix that by dropping the reference to the `GLocalFileMonitor` after
unlocking.
Diagnosed by Ting-Wei Lan. The bug was originally introduced by me in
commit 592a13b483.

Relax the requirement for the test to only be compiled/run under gcc,
since a version of LLVM was released which supports `--add-symbol`.
`objcopy` should be overrideable to be `llvm-objcopy` by using a machine

If there were more subpatterns in the regex than matches (which can
happen if one or more of the subpatterns are optional),
`g_match_info_fetch()` was erroneously returning `NULL` rather than the
empty string. It should only return `NULL` when the `match_num`
specifies a subpattern which doesn’t exist in the regex.
This is complicated slightly by the fact that when using
`g_regex_match_all()`, more matches can be returned than there are
subpatterns, due to one or more subpatterns matching multiple times at
different offsets in the string.
This includes a fix for a unit test which was erroneously checking the
broken behaviour.
