[PATCH] Make EXT2_DEBUG work again

Browse Source 
This patch makes EXT2_DEBUG work again.  Due to lack of proper include
file, EXT2_DEBUG was undefined in bitmap.c and ext2_count_free() is left
out.  Moved to balloc.c and removed bitmap.c entirely.

Second, debug versions of ext2_count_free_{inodes/blocks} reacquires
superblock lock.  Moved lock into callers.
