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.

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().
To avoid iterating threads in g_static_private_free(), defer freeing
the per-thread data to thread exit. The one complication here is
that it is possible for the static private index to be reused while
'old' data is still around. To deal with that case, store the 'owner'
with each per-thread data node, and free old data in
g_static_private_get() if the owner doesn't match. The remaining
possibility that a private index could be reused by a GStaticPrivate
with the same address is sufficiently unlikely that we can probably
ignore it.
With this change, per-thread data is now truly private again,
and we can drop the lock for it as well.

We lack SRWLock on Windows XP, so we use CRITICAL_SECTION to emulate it
there. SRWLock is non-recursive, but CRITICAL_SECTION will happily
allow itself to be acquired multiple times by the same thread.
We need to detect if our second acquire succeeded because of the
recursive nature of CRITICAL_SECTION. In the case of a _lock()
operation, we would normally have deadlocked, so abort. In the case of
a _trylock() operation, we need to ensure that FALSE is properly
returned.
Problem caught by Matthias Clasen and Chun-wei Fan.

-Include gthread.h in gregex.c as g_once_init_enter and g_once_init_leave
are used.
-Define prototype for g_thread_DllMain in gthreadprivate.h for Windows
