g_thread_init() has done nothing since 2.32, so while the function
still can be used if "g_thread_init() has not yet been called",
it won't do nothing in that case, it will just perform normally.
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.
Make the POSIX backend a little bit more like the win32 one in terms of
how we deal with joinability.
Calling g_system_thread_join() is now optional, and
g_system_thread_wait() can be safely called by multiple threads.
There is no longer any internal concept of joinability.
Wrap GRealThread in a GThreadPosix that includes its own pthread_t field
called "system_thread" and use that instead of the generic field in
GRealThread.
Add g_system_thread_new() and g_system_thread_free(), implemented with
GSlice. Use those instead of g_new() and g_free().
Presently, the backends are both doing the same thing. This will change
soon.
The markup here was not only broken, it was also unnecessary,
since gtk-doc knows to apply <function></function> tags to things
that end with () already.
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.

Modify the POSIX implementation of the synchronisation primatives to use
the same ABI as Windows: one pointer for each type.
This frees us from having to #include <pthread.h> and avoids the problem
with pthread_rwlock_t not being defined under certain compiler defines.
A few more changes are expected to the ABI -- they will be committed
separately.

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().
This was ignored on Windows. On POSIX, where supported, it controlled
if we ended up with a proper system thread or a user-mode thread. Linux
did not support this.
Switch 'self' 'join' and 'create' from using the vtable to being called
via normal g_system_thread_* internal API (implemented in each of
gthread-{posix,win32}.c).
Again, we can put NULL in the vtable since these were never used from
gthread.h.
Thread priorities were already documented as not working on Solaris, and
they are meaningless on Linux unless the process separately requests
realtime scheduling (and even then, it appears only to work as root).
We can safely put a NULL into the vtable for set_priority since nothing
outside of gthread.c ever calls this (and that call is gone).
