ChangeLog, e2fsck.h, pass1.c, pass1b.c:
  e2fsck.h:
  pass1.c (mark_table_blocks, e2fsck_pass1): Remove
  	ctx->block_illegal_map, since it's not needed by pass1, and pass1b has
  	been modified to calculate it manually if needed.  This reduces the
  	memory footprint needed by e2fsck.
  pass1b.c (check_if_fs_block): New static function which returns
  	whether or not a block overlaps with filesystem metadata.  This
  	replaces consulting the block_illegal_map bitmap.
util.c:
  Make resource tracking message more concise.
