Assume unix platforms support the original POSIX.1 standard.
Specifically, assume that if G_OS_UNIX, then we have chown(),
getcwd(), getgrgid(), getpwuid(), link(), <grp.h>, <pwd.h>,
<sys/types.h>, <sys/uio.h>, <sys/wait.h>, and <unistd.h>.
Additionally, since all versions of Windows that we care about also
have <sys/types.h>, we can remove HAVE_SYS_TYPES_H checks everywhere.
Also remove one include of <sys/times.h>, and the corresponding
configure check, since the include is not currently needed (and may
always have just been a typo for <sys/time.h>).

Otherwise we have to rely on pthread_cond_timedwait() actually using
the monotonic clock, which might be true or not. On Android at least
it is using the realtime clock, no pthread_condattr_setclock() is available
but instead pthread_cond_timedwait_monotonic() can be used.
This reverts commits dfbac178bd and
56348210f3.
These two commits introduce undesirable behaviour and were made with no
apparent approval from anybody at all, and without reference to a bug or
mailing list discussion.
In order to fully undo the effects of g_mutex_init(),
it is necessary to reset the internal mutex pointer
back to NULL so that a later call to g_mutex_init()
actually works as expected.
On platforms where dependent loads can be reordered (alpha) and we have
exotic implementation of pthread_mutex_lock() it could be possible that
our implementation of g_mutex_lock() is unsafe.
Always use atomic operations to avoid this possibility.

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().
