Create new functions ext2fs_{set,get}_{inode,block}_bitmap_range()
which allow programs like e2fsck, dumpe2fs, etc. to get and set chunks
of the bitmap at a time.
Move the representation details of the 32-bit old-style bitmaps into
gen_bitmap.c.
Change calls in dumpe2fs, mke2s, et. al to use the new abstractions.

Move the 32-bit specific bitmap code into gen_bitmap.c, and the
high-level interfaces into bitmaps.c. Eventually we'll move the
new-style bitmap code into gen_bitmap64.c, but first we need to
isolate the code with knowledge of the bitmap internals in one place
first.
In this patch we move allocation, free, copy, clear, set_padding, and
fudge_end function into gen_bitmap.c, and make sure that the bitmaps.c
and bitops.c no longer have any knowledge of the bitmap internals.

Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap to
gen_bitmap.c as normal functions. (This saves space and doesn't
significantly change the speed of e2fsck on a P-III.)
ChangeLog:
Add missing log entry for unix.c.
