Switch GCond to using monotonic time for timed waits by introducing a
new API based on monotonic time in a gint64: g_cond_wait_until().
Deprecate the old API based on wallclock time in a GTimeVal.
Fix up the gtk-doc for GCond while we're at it: update the examples to
use static-allocated GCond and GMutex and clarify some things a bit.
Also explain the rationale behind using an absolute time instead of a
relative time.
Hide the definition of struct _GThread in gthreadprivate.h for now.
This is possibly an API break -- although the structure contents were
undocumented and it was not safe to access them in a meaningful way,
someone may have tried to do it anyway. We'll leave it here for a while
to see if it causes any problems.
Avoid merging its contents with GRealThread for now, just incase we need
to expose it again.
We'll hold out on this until someone has a really convincing reason for
why they need to control the stack size.
If we do decide to add it back, it should probably have a name like
_new_with_stack_size(), not _full().
And remove the 'joinable' argument from g_thread_new() and
g_thread_new_full().
Change the wording in the docs. Clarify expectations for
(deprecated) g_thread_create().
...instead of having a 'next' pointer in the GThread struct.
Now GThread contains no fields used only by deprecated code (except for
the rather generic setup function field).
Thanks to the modifications in 3d4846d92309d001697c2827660fa41b5c63dbc4,
GStaticPrivate is not so directly tied in with GThread anymore. It is
now a simple matter to cut it out completely by using a GPrivate to
store the GArray instead of storing it in the GThread.
Everything was OK as long as GMutex was backed by pthread_mutex_t on
POSIX. Since this is no longer the case, the ABI of GStaticMutex was
broken.
Fix that up by using pthread_mutex_t directly in the structure. Since
that's potentially incompatible with our GMutex implementation, set
g_thread_use_default_impl to FALSE to cause the fallback code (which
manually allocates a GMutex) to run, even in the case of
already-existing code (without the need for a recompile). This will
cause the pthread_mutex_t part of the struct to be completely ignored.
Give the macro wrapper treatment to g_once_init_enter() and leave() in
the same style that we did for gatomic.
It is now possible to use these macros with any pointer-sized object,
and not just gsize. The leave() macro ensures that the initialisation
result is a compatible type with the pointer that it is being written
to.
Just like with gatomic, there could be problems caused by use of (void*)
casts. We'll see how that goes, and reevaluate if necessary.

Add a little bit more room in the ABI for our synchronisation primatives
since we're going to need it when we add native implementations on
Linux.
Also: rename the pointer field and add /*< private >*/ annotations.
All locks are now zero-initialised, so we can drop the G_*_INIT macros
for them.
Adjust various users around GLib accordingly and change the docs.

This commit moves GStaticPrivate, g_thread_foreach and all
related functions and variables to gthread-deprecated.c. We
introduce some internal API to make this possible.
g_thread_foreach is not a very useful function, since there is
virtually nothing you can do with a GThread*, and implementing
it requires us to keep a list of threads around.
GStaticPrivate has been made redundant by adding comparable
capabilities to GPrivate.

Deprecate both g_thread_create functions and add
g_thread_new() and g_thread_new_full(). The new functions
expect a name for the thread.
Change GThreadPool, GMainContext and GDBus to create named threads.

Take out the half-private g_private_init() stuff and replace it with a
G_PRIVATE_INIT macro that allows specifying a GDestroyNotify.
Expose the GPrivate structure in a public header.
Add a g_private_replace() to (sort of) match the functionality of
g_static_mutex_set().
Improve the documentation.
Deprecate g_private_new().
Create a deprecated/ directory that we can start moving ancient chunks
of code to. Start with GAllocator, GMemChunk and related APIs.
Also drop all mention of them from the docs.
