Rename MAP_LEN internal macro to OBJ_MAP_LEN

(refactoring)

* doc/tree.md (A picture): Rename MAP_LEN to OBJ_MAP_LEN.
* obj_map.c [MARK_BIT_PER_GRANULE] (GC_add_map_entry): Likewise.
* include/private/gc_priv.h (hblkhdr.hb_marks): Reformat comment (to
have quoted phrase on a line).
* include/private/gc_priv.h [MARK_BIT_PER_GRANULE] (MAP_LEN): Rename
to OBJ_MAP_LEN.
* obj_map.c [MARK_BIT_PER_GRANULE] (GC_add_map_entry): Replace
BYTES_TO_GRANULES(HBLKSIZE) to OBJ_MAP_LEN.
