* allchblk.c (GC_allochblk_nth): Dont overlook available space if
GC disabled, correctly convert GC_finalizer_mem_freed to byte,
total_size to words.
* dyn_load.c (win32 GC_register_dynamic_libraries): Consider only
MEM_IMAGE regions.
* mach_dep.c (GC_with_callee_saves_pushed): separate into new function,
and indent appropriately.
* mark_rts.c (GC_approx_sp): Access stack.
* pthread_stop_world.c: (GC_suspend_handler): Explicitly push
callee-saves registers when appropriate.
(GC_stop_world): Handle EINTR from sem_wait (sync with Mono GC).
