Fix bug re noninteractive multithreaded memory allocation.

* emacs.c (malloc_enable_thread): Hoist extern decl to top level.
(main) [HAVE_PTHREAD && !SYSTEM_MALLOC && !DOUG_LEA_MALLOC]:
Invoke malloc_enable_thread even when not interactive.
Problem reported by Ken Brown in <http://bugs.gnu.org/14569#275>.
* process.c (init_process_emacs) [CYGWIN]: Tickle glib even
in this case, since the underlying bug has now been fixed.
