	* alloc.c, backgraph.c, headers.c, include/private/gc_priv.h:
	Maintain GC_our_memory and GC_n_memory.
	* dbg_mlc.c (GC_print_smashed_obj): Improve message.
	(GC_print_all_smashed_proc): Pass client object address instead of
	base.
	* dyn_load.c (sort_heap_sects): New.  (GC_register_map_entries):
	Register sections that are contiguous and merged with our heap.
	* malloc.c, os_dep.c (GC_text_mapping): Check for just base name
	of libraries.
	* malloc.c (calloc): Check for special callers even with
	USE_PROC_FOR_LIBRARIES. Move assertion.  Add rudimentary
	malloc/free tracing.
	* misc.c: No longer call GC_init_lib_bounds explicitly.
	* thread_local_alloc.c (GC_malloc, GC_malloc_atomic): Always
	initialize on demand.
	* tests/test.c: Call GC_INIT only when required.
