Bitmap Operations
-----------------

 - Function: void ext2fs_mark_block_bitmap (ext2fs_block_bitmap BITMAP,
          blk_t BLOCK)
 - Function: void ext2fs_unmark_block_bitmap (ext2fs_block_bitmap
          BITMAP, blk_t BLOCK)
 - Function: int ext2fs_test_block_bitmap (ext2fs_block_bitmap BITMAP,
          blk_t BLOCK)
     These functions set, clear, and test bits in a block bitmap BITMAP.

 - Function: void ext2fs_mark_inode_bitmap (ext2fs_inode_bitmap BITMAP,
          ext2_ino_t INODE)
 - Function: void ext2fs_unmark_inode_bitmap (ext2fs_inode_bitmap
          BITMAP, ext2_ino_t INODE)
 - Function: int ext2fs_test_inode_bitmap (ext2fs_inode_bitmap BITMAP,
          ext2_ino_t INODE)
     These functions set, clear, and test bits in an inode bitmap
     BITMAP.

 - Function: void ext2fs_fast_mark_block_bitmap (ext2fs_block_bitmap
          BITMAP, blk_t BLOCK)
 - Function: void ext2fs_fast_unmark_block_bitmap (ext2fs_block_bitmap
          BITMAP, blk_t BLOCK)
 - Function: int ext2fs_fast_test_block_bitmap (ext2fs_block_bitmap
          BITMAP, blk_t BLOCK)
 - Function: void ext2fs_fast_mark_inode_bitmap (ext2fs_inode_bitmap
          BITMAP, ext2_ino_t INODE)
 - Function: void ext2fs_fast_unmark_inode_bitmap (ext2fs_inode_bitmap
          BITMAP, ext2_ino_t INODE)
 - Function: int ext2fs_fast_test_inode_bitmap (ext2fs_inode_bitmap
          BITMAP, ext2_ino_t INODE)
     These "fast" functions are like their normal counterparts; however,
     they are implemented as inline functions and do not perform bounds
     checks on the inode number or block number; they are assumed to be
     correct.  They should only be used in speed-critical applications,
     where the inode or block number has already been validated by
     other means.

 - Function: blk_t ext2fs_get_block_bitmap_start (ext2fs_block_bitmap
          BITMAP)
 - Function: ext2_ino_t ext2fs_get_inode_bitmap_start
          (ext2fs_inode_bitmap BITMAP)
     Return the first inode or block which is stored in the bitmap.

 - Function: blk_t ext2fs_get_block_bitmap_end (ext2fs_block_bitmap
          BITMAP)
 - Function: ext2_ino_t ext2fs_get_inode_bitmap_end
          (ext2fs_inode_bitmap BITMAP)
     Return the last inode or block which is stored in the bitmap.
