[glibmm] Thread: Use g_thread_new() instead of g_thread_create().

[Murray Cumming <murrayc src gnome org>]

commit 353c3dc9f70cccc3cbe90686cd9c5e42112999a7
Author: Murray Cumming <murrayc murrayc com>
Date:   Fri Oct 21 11:10:31 2011 +0200

    Thread: Use g_thread_new() instead of g_thread_create().
    
    * glib/src/thread.[hg|ccg]: create(): Replace use of (deprecated)
      g_thread_create() with g_thread_new(), ignoring the joinable parameter.
      create(lots of parameters): Deprecate this, because the parameters are
      ignored by g_thread_create_full() now.
