branch. See the ChangeLog for details of the changes.

In brief overview:

 - The set of threading functions can be set
 - A default implementation is provided in -lgthread
 - All static data structures are locked using these
   functions if g_thread_init() is called.

1998-12-11 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread/gthread-nspr.c, configure.in: Added new default thread
implementation on top of the mozilla nspr library.
* gmem.c, gmessaged.c, gthread/gthread.c, gthread/gthread-*.c:
Changed GStaticMutex and GStaticPrivate in gmem.c and gmessages.c
into GMutex and GPrivate resp. to make error reporting and use of
gmem possible in most (not all, though) gthread functions. Also
initialized the modules via new init functions.
* configure.in: Fixed syntax bug in definition of type
GStaticMutex.
* gthread/testgthread.c: Updated to work with nspr, but see note
there for remaining problems.
1998-12-10 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gmutex.c, glib.h: Now abort, if a mutex/cond/private is
allocated before the thread system is set up.
* gthread/gthread.c (g_thread_init): Removed g_thread_try_init(),
as it is not necessary. Changed the error message. Corrected logic
for g_thread_use_default_impl.
* gmutex.c (g_mutex_init): Keep the thread private data array
after calling g_thread_init().
1998-12-09 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gthread/testgthread.c (new_thread): Now also working for posix
threads; (wait_thread): Now a better implementation, that does not
use 100% CPU.
* Made the thread related code follow GNU coding standard.
* Made a comment (HOLDS:) above each function, that expects the
given locks to be held.
* Changed try_lock to trylock throughout.
* glib.c: Eventually removed the #if 0'ed code for old GStaticMutex.
* glib.c: Corrected g_trylock macro for G_DEBUG_LOCKS.
* gmain.c (g_main_poll_add_unlocked): first take a new poll record
form the poll_free_list.
* gmem.c, gstrfuncs.c, gutils.c: Made it MT safe.
* gthraed/*.c: Added copyright headers.
* gthread/gthread-solaris.c: do not use g_log for errors, as g_log
uses these module and endless recursions might happen, just use a
plain fprintf(stderr,...).
* gthread/gthread.c (g_thread_try_init): Call g_mutex_init().
* gthread/testgthread.c: updated test program.

* Start at adding thread-safety. (mostly work
of Sebastian Wilhelmi <wilhelmi@ira.uka.de>)
- configure.in now looks for a system thread implementation.
Currently support is included for POSIX threads
and Solaris threads. The default support is built
into a separate library -lgthread.
- The thread implementation can be modified by passing
a vector of functions g_thread_init().
- The default or supplied functions are used to
implement a small set of thread functions for
mutexes, condition variables, and thread-private
data.
- GLib now uses these functions to provide thread
safety. (In the sense that all global static
data is locked... individual structures must still
be locked by the caller.)

* configure.in: always define G_HAVE_INLINE if __cplusplus is
