Define GC_get_parallel and GC_set_markers_count in single-threaded GC
These are no-op definitions in case of the collector is built as
a single-threaded one. This is useful for single threaded clients
to be able to call these functions regardless of the collector is
multi-threaded or not.
* include/gc/gc.h [GC_THREADS] (GC_parallel): Reformat comment.
* include/gc/gc.h (GC_get_parallel, GC_set_markers_count): Declare
unconditionally.
* misc.c [!PARALLEL_MARK] (GC_set_markers_count): Define (as no-op).
* misc.c [!THREADS] (GC_get_parallel): Define (return 0).
* pthread_support.c (GC_set_markers_count): Define only if
PARALLEL_MARK; remove GC_ATTR_UNUSED.
* win32_threads.c (GC_set_markers_count): Likewise.
* tests/initfromthread.c (main): Call GC_get_suspend_signal() instead
of GC_get_parallel().
