Fix setup_mark_lock missing prototype

(and do not call it if no parallel marker)

* include/private/pthread_support.h (GC_setup_mark_lock): Remove
prototype.
* misc.c (GC_init): Remove GC_setup_mark_lock call (move it to
GC_thr_init).
* pthread_support.c (setup_mark_lock): Rename from GC_setup_mark_lock;
add prototype (only if PARALLEL_MARK).
* pthread_support.c (GC_thr_init): Call setup_mark_lock() unless
available_markers_m1 is 0.
