Owen Taylor 931ea95265 This commit merges the glib-threads branch into the main
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.
