Theodore Ts'o 830b44f438 e2fsck: use different bitmap types as appropriate 
Now that we have multiple backend implementations of the bitmap code,
this commit teaches e2fsck to use either the most appropriate backend
for each use case.

Since we don't know for sure if we will get it all right, the default
choices can be overridden via e2fsck.conf.  The various definitions
are shown here, with the current defaults (which may change as we add
more bitmap implementations and as learn what works better).

; EXT2FS_BAMP64_BITARRAY is 1
; EXT2FS_BMAP64_RBTREE is 2
; EXT2FS_BMAP64_AUTODIR is 3
