Implement g_ascii_strto{d,ll,ull} and g_ascii_formatd using
xlocale functions where available. This is slightly faster
and a lot less icky than our homegrown code.

Previously, we were returning an empty buffer for all filenames
where fstat() gives a size of 0. But this is only appropriate
for regular files.
Also improve the documentation around this issue. Based on a
patch by Ryan Lortie.

GStaticMutex makes use of atomic operations to initialise itself. We
were using GStaticMutex from the emulated case of gatomic. Use pthreads
directly to avoid unbounded recursion in this case.
Otherwise, we could use-after-free the GDBusWorker, if its last-unref
is immediately after _g_dbus_worker_new returns (before the worker thread
does its initial read).

This member is written in _g_dbus_worker_stop from arbitrary threads, and
read by the worker thread, so it should be accessed atomically.

We can't safely close the output part of the I/O stream until any
pending write or flush has been completed. In the worst case, this could
lead to an assertion failure in the worker (when the close wins the
race) or not closing the stream at all (when the write wins the race).

num_writes_pending was a counter, but it only took values 0 or 1, so make
it a boolean: it would never make sense to be trying to write out two
messages at the same time (they'd get interleaved).
Similarly, we can never be writing and flushing at the same time (that'd
mean we were flushing halfway through a message, which would be pointless)
so combine it with flush_pending too, calling the result output_pending.
Also assert that it takes the expected value whenever we change it,
and document the locking discipline used for it, including a subtle
case in write_message_in_idle_cb where it's not obvious at first glance
why we don't need the lock.
(Having the combined boolean at the top of the block of write-related
struct members improves struct packing on 64-bit platforms, by packing
read_num_ancillary_messages and output_pending into one word.)

Add an extra state pointer and an extra GDestroyNotify function
to the 'Chunk' definition... allowing bindings to attach some extra
state to memory chunks (to get memory management correctly from
language bindings).
Bug #589887
The GApplication test case tried to fork() while using GMainLoop,
causing problems. Avoid doing that by splitting the child process into
a separate program and spawning it in the usual way.

The 'key' variable is no longer valid outside the cycle, owned and
probably already freed by GVariant. This causes apps to segfault
when proxy is constructed and a property on remote d-bus service
changes (actually is invalidated). Looks like a typo anyway.

Our hashing of non-ASCII strings was undefined due to the fact that
'char' is signed on some platforms, unsigned on others. Always use a
signed char.

* Do not exclude the last used being set from the default list
