GThreadPool defaulted to 0 for max_unused_threads (meaning thread-pool
threads would exit immediately if there was not already another task
waiting for them), and 0 for max_idle_time (meaning unused threads
would linger forever, though this is only relevant if you changed
max_unused_threads).
However, GIOScheduler changed the global defaults to 2 and 15*1000,
respectively, arguing that these were more useful defaults. And they
are, so let's use them.

g_source_get_context() was checking that the source wasn't destroyed
(since a source doesn't hold a ref on its context, and so
source->context might point to garbage in that case). However, it's
useful to be allowed to call g_source_get_context() on a source that
is destroyed-but-currently-running.
So instead, let g_source_get_context() return the context whenever
it's non-NULL, and clear the source->context of any sources that are
still in a context's sources list when the context is freed. Since
sources are only removed from the list when the source is freed (not
when it is destroyed), this means that now whenever a source has a
non-NULL context pointer, then that pointer is valid.
This also means that g_source_get_time() will now return-if-fail
rather than crashing if it is called on a source whose context has
been destroyed.
Add tests to glib/tests/mainloop to verify that g_source_get_context()
and g_source_get_time() work on destroyed sources.

Verify that
- g_source_get_time() does not change within a single callback
(even if the real time does)
- g_source_get_time() does not change between different callbacks in
the same mainloop iteration
- g_source_get_time() does change between iterations if the real
time did.

g_utf8_strup() tries to call setlocale() before starting to compute
the length of its first argument. Calling setlocale() can return NULL
(as specified in the man page), and obviously that happens on android.

The old (length) annotation actually wasn't being read. Changing
it to an array was telling g-i that it was an array of utf8, which
is clearly not true.
We *could* add (element-type guint8), but that would change it to a
byte array, as opposed to the original utf8 version.
Just removing the annotation should bring us back to where we
were, which was fine.

Bug 680074 shows that we may end up in situations where only
some of the xlocale functions we need are available. Rather than
trying to find the minimal set of required functions for each
use, define a global USE_XLOCALE and only use any xlocale functions
if we have a full set.
Child sources are supposed to be blocked when their parents are, so
when adding a source to a blocked source, block the child too. Fixes a
warning when unblocking the parent.
On Windows, GetEnvironmentVariable() returns 0 for empty variables.
Checking GetLastError() == ERROR_ENVVAR_NOT_FOUND helps make a
difference between a variable that does not exist or an empty one
which should return "".

The current code create the strv array incorrectly, it is too big and
leaves invalid holes. This may result in crashes when freeing the
returned value.

Many (if not "almost all") programs that spawn other programs via
g_spawn_sync() or the like simply want to check whether or not the
child exited successfully, but doing so requires use of
platform-specific functionality and there's actually a fair amount of
boilerplate involved.
This new API will help drain a *lot* of mostly duplicated code in
GNOME, from gnome-session to gdm. And we can see that some bits even
inside GLib were doing it wrong; for example checking the exit status
on Unix, but ignoring it on Windows.

String validation was done by checking if the string was valid utf8 and
ensuring that the first non-utf8 character was the last character (ie:
the nul terminator).
No check was actually done to make sure that this byte actually
contained a nul, however, so it was possible that you could have a
string like "hello\xff" with length 6 that would correctly validate.
Fix that, and test it.
If GLIB_VERSION_MIN_REQUIRED or GLIB_VERSION_MAX_ALLOWED was defined
to a future value, we were essentially treating it as
GLIB_VERSION_0_0. Fix to treat it as being in the future instead.

The docs for GString should really mention GByteArray, and what makes
it different. Drop the comparison to Java which is dated and actually
inaccurate (because StringBuffer operates on Unicode).
While we're here, add g_string_free_to_bytes(), which further
complements the spread of GBytes-based API. For example, one can
create a buffer using GString, then send it off via
g_output_stream_write_bytes().

The Since tag for these was saying 2.28 but it was actually added in
2.31. It looks like all of the Since tags list stable version numbers
so this patch bumps that up to 2.32.

Since PCRE 8.00 it supports a variant of PCRE_NOTEMPTY that works
similarly except that it only applies to the start of the matched string
but permits empty matches further in.
g_regex_get_compile_get_compile_flags() and g_regex_get_match_flags()
were leaking PCRE flags that don't exist in the corresponding
public GRegexCompileFlags and GRegexMatchFlags; this change masks
these internal flags.
These flags override the compile option at match time. They use PCRE_BSR_ANYCRLF
and PCRE_BSR_UNICODE, resp., which make \R match only CR, LF and CRLF, or any
Unicode newline character or character sequences, resp.
When using the system PCRE, and it was compiled with incompatible options,
the code was returning from inside a g_once_init_enter/leave block without
calling g_once_init_leave().
