Export GC_print_free_list()

Note: this function is not used by GC itself.

* include/gc_inline.h (GC_print_free_list): New public API prototype.
* reclaim.c [!NO_DEBUGGING]: Include gc_inline.h (to check that
GC_print_free_list prototype matches the definition).
* reclaim.c [!NO_DEBUGGING] (GC_print_free_list): Define as public
(GC_API+GC_CALL); remove "ok" local variable; add assertions about kind
and sz_in_granules maximum values.
