Use the opt-out mechanism introduced in gtk-doc 1.16 to work
around problems with the _utf8 renaming games that the win32
port is playing in our headers.

See https://bugs.freedesktop.org/show_bug.cgi?id=37890#c6 where it was
discovered that dbus-send(1) actually doesn't work (either libdbus-1's
flush implementation or dbus-send(1)'s usage of it is broken) so it's
useful to have here.

g_queue_remove() should return a boolean so callers can verify that an
element was found and removed, as in the following example:
if (g_queue_remove (queue, referenced_object))
g_object_unref (referenced_object);
Similarly, g_queue_remove_all() should return the number of elements
found and removed.

When getting the mutex implementation of a static mutex, avoid taking the global
lock every time but only take the lock when there was no mutex and we need to
create one.

Instead of converting the string to a quark and comparing quarks we
use the new lockless g_quark_to_string and just compare the quarks
in the datalist with the given string.
This means we avoid the global lock for string to quark. Additionally
most of the time the data list will be quite short, so the cost of
doing the sting comparisons is likely similar to that of the quark
hashtable lookup (which does at least one string comparison for a
successfull lookup).

We do this by assigning to g_quarks atomically and leaking it when
replacing it atomically. Then its safe to consume the array
on the reader side (atomically).
Also, since we're leaking quarks on growing, bump the block size
so that we're not leaking as much. gtk3-demo allocates > 1500 quarks,
and gnome apps > 3000. I'm setting the block to 2048 which means no
leaks for small gtk3 apps and just one leak for gnome apps.

This implementation uses a per-list bitlock for user data, and a
simple array rather than a linked list which uses less memory and less
allocations. It also gets better cache behaviour since related things
are stored close to each other.

The __sync_fetch_and_or() operation on x86 is a bit suboptimal when the
result isn't ignored. Normally we could use the 'lock or' assembly
instruction to accomplish this, but this instruction discards the
previous value.
In order to work around this issue, GCC is forced to emit a
compare-and-exchange loop.
We can easily use the 'lock bts' instruction, though. It can't be used
in the general case for __sync_fetch_and_or() but it works great for our
case (test and set a single bit).
I filed a bug against GCC[1] to get this exposed as a new intrinsic (or
have the optimiser detect the case) but until then we'll hand-code it on
x86 and amd64.
The uncontended case sees a 31% improvement on my test machine.

g_variant_get_strv and g_variant_get_bytestring return arrays that
are null terminated and have an explicit length. Since gjs doesn't
support (out) arrays with length, mark them also null-terminated
(but leave the length annotation, so pygobject can remove the argument)

This avoids the generated types (e.g. ExampleAnimal, ExampleCat,
ExampleObject and ExampleObjectManagerClient) being referenced in the
core gio docs. This was requested by Matthias.

Unify it more with the rest of the signal handling code. There's
no reason not to specify SA_RESTART and SA_NOCLDSTOP for flags
always, so just do it.
Remove unnecessary initialization, and push the internal API
towards just ensure_unix_signal_handler_installed_unlocked().

I can't see a reason to spin until the worker thread runs, so don't.
This avoids ugly sched_yield() calls that show up in strace and
annoy me; the code is cleaner now too.
We now grab the types needed for the WebKit workaround in the
thread creation area, but only release them when the thread itself
exits.

From discussion, GVariantIter is not useful for bindings, but
GVariantBuilder may be.

In resolve_sync function in gthreadedresolver.c, if g_thread_pool_push
fails due to thread creation failure, we are just simply appending the
data to the queue of work to do. After the failure, we might wait
indefinitely in g_cond_wait. In case of g_thread_pool_push failure,
propagate the error so that this function does not blocks forever in
case of failure.
