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 use of system_thread is now limited to joining. We don't do that
for threads that we didn't create for ourselves, so we don't need to
call g_system_thread_self() to fill in system_thread for those.
...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).
It is possible for _g_io_module_get_default() to be called recursively
(eg, if a module of one type is loaded that tries to look up gsettings
from its init() method and ends up causing the gsettings module to be
loaded). So use a recursive mutex.
Thanks to the modifications in 3d4846d923,
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.
Get rid of _CRT_SECURE_NO_WARNINGS and _CRT_NONSTDC_NO_WARNINGS
from the preprocessor definitions as those two macros are now defined
in msvc_recommended_pragmas.h, which is force-included in these projects
via the property sheets. This will silence C4005 warnings on macro
redefinition.
Don't disable warning C4996 as that is the Visual C++ warning triggered by
__declspec(deprecated) and __declspec(deprecated('..."))-disabling that
warning will defeat the purpose of G_DPRECATED/G_DEPRECATED_FOR.
For people who don't want to see the GLib deprecation warnings during GLib
compilation, define GLIB_DISABLE_DEPRECATION_WARNINGS in the projects or
property sheet.
Unlike G_GNUC_... macros, the new G_DEPRECATED[_FOR] are
meant as abstractions that work with different compilers.
Using a new name also lets us restrict it to 'must be placed
before the declaration', which works with more compilers.

The definitions of _GMutex* and G_STATIC_MUTEX_INIT is now found in
glib/deprecated/gthread.h, and should no longer be in the mainline
code, so remove them from here.
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.
