It was documented at strange places: in g_sequence_search*() and
g_sequence_lookup*(), but how to insert and sort data is not done by
those functions.
So instead, add the information to the class description (since it
involves several functions), and add also the information in
g_sequence_insert_sorted() and g_sequence_insert_sorted_iter() as a kind
of warning when using those functions.
Note that before this commit, it was not explained *why* it is better to
call g_sequence_sort() after doing a lot of unsorted insertions. Now it
is documented as "more efficient" (I think it's the only reason that
makes sense, otherwise why was it documented?).

When debug output is enabled then certain messages will be logged to
stdout. stdout however is block buffered by default when it isn't going
to a TTY meaning that debug logging will not be flushed out properly
when it is being redirected. One example of this happening may be tests
that rely on parsing g_debug messages.
Adding an explicit fflush ensures all log messages will reach the output.

On i386, we were seeing that this calculation was producing an incorrect
result, probably because usec was being stored in an 80-bit register
before being written back into a 64-bit float in memory. If we mark the
variables as volatile, they are not stored in registers and we avoid
this bug.
gtk-doc doesn’t support them any more since it was ported to Markdown,
so they end up appearing in the generated documentation, which isn’t
great.
Mostly, they were used to split up things invisibly, which we can do in
other ways.

gpointer* cannot be aliased with arbitrary types. In order to fix
-Wstrict-aliasing=2 warnings with the g_clear_pointer() macro, we need
to cast through char*, which is allowed to alias with anything.
Even if we don’t make GLib strict-aliasing safe, it’s important to
ensure this macro is safe, since it could be used from projects which do
compile with -fstrict-aliasing.

When using g_key_file_get_locale_string() or get_locale_string_list(),
the GKeyFile must have been loaded with G_KEY_FILE_KEEP_TRANSLATIONS if
the lookup locale differs from the one which was current when the key
file was loaded.

Commit 281e3010 narrowed the race between GCancellable::cancelled and
GCancellableSource's finalize(), but did not prevent it: there was
nothing to stop cancellation from occurring after the refcount drops
to 0, but before g_source_unref_internal() bumps it back up to 1 to
run finalize().
GCancellable cannot be expected to detect that situation, because the
only way it has to detect last-unref is finalize(), but in that
situation finalize() hasn't happened yet.
Instead of detecting last-unref, relax the precondition a little
to make it detect finalization: priv is only poisoned (set to NULL)
after the finalize() function has been called, so we can assume that
GCancellable has already seen finalize() by then.

If we don't take the lock, then we don't have the necessary
"happens before" relationships to avoid this situation:
* source->priv->ready_time was equal to ready_time until recently
* another thread has set source->priv->ready_time to a different value
* that write hasn't become visible to this thread yet
* result: we should reset the ready_time, but we don't

The introspection scanner chokes fairly badly on the types we create,
and that got even worse when the autolist support landed. Now, every
time we declare a new GObject type we automatically get incomplete
aliases to container types that gobject-introspection and Vala do not
know how to handle.
Since the autoptr machinery is not really introspectable to begin with,
as it's a C utility extension that depends on the C compiler being used
to compile a C project that depends on GLib, we can mark the whole
section as non-introspectable using the __GI_SCANNER__ pre-processor
symbol.

Rather than unreffing them _after_ finalising the GSource and freeing
its struct. This fixes the case where the GSourceCallbackFuncs data
contains a pointer to the GSource, and the unref() function operates on
that pointer, e.g. by calling g_source_destroy(). This happens when
using g_source_set_dummy_callback() on a GSource, as the generated
GClosure needs to destroy the GSource when it is invalidated, which
could happen (at latest) when the GSourceCallbackFuncs.unref() function
is called during finalisation of the GSource.
By moving the GSourceCallbackFuncs.unref() invocation higher up in
g_source_unref_internal(), it becomes re-entrancy-safe for GSource
methods.

If nl_langinfo() doesn’t support a particular item, it returns the empty
string. We should check for that and return NULL from
g_date_time_format() accordingly, otherwise the user could unwittingly
end up with a formatted date/time which is missing some or all of its
components.
This arose with %r in de_DE, which is unsupported by nl_langinfo()
because Germans almost never write time in 12-hour format.

When doing a level traverse of a GNode with depth of -1, the depth was
implicitly being converted to an unsigned integer. This worked (making
the depth limit G_MAXUINT), but was a bit mystical.
Change g_node_depth_traverse_level() to explicitly take a signed depth
and handle it appropriately.
