efficiently.
Like the find_first_zero family of functions, provide a generic O(N)

Also, expand the test cases for ext2fs_find_first_zero_*() functions.

libext2fs: teach the ext2fs_*_block_bitmap_range2() about clusters
The ext2fs_{mark,unmark,test}_block_bitmap2() functions understand
about clusters, and will take block numbers and convert them to
clusters before checking the bitmap. The
ext2fs_*_block_bitmap_range2() functions did not do this, which made
them inconsistent. Fortunately, nothing has depended on this
incorrect behavior, and in fact most of the usage of these functions
have only recently been added, and only for optimizations that were
only enabled for non-bigalloc file systems.
So this is a change in previously exported functions, but (a) it
doesn't change the behavior at all for non-bigalloc file systems, and
(b) the change is more likely to fix bugs for bigalloc file systems.
For example, this change fixes a problem with resize2fs and bigalloc
file systems.

libext2fs: Implement ext2fs_find_first_zero_generic_bmap().
This function searches a bitmap for the first zero bit within a range.
It checks if there is a bitmap backend specific implementation
available (if the relevant field in bitmap_ops is non-NULL). If not,
it uses a generic and slow method by repeatedly calling test_bmap() in
a loop. Also change ext2fs_new_inode() to use this new function.
This change in itself does not result in a large speedup, rather it
refactors the code in preparation for the introduction of a faster
find_first_zero() for bitarray based bitmaps.

libext2fs: add a bitmap implementation using rbtree's
For a long time we had a bitarray backend for storing filesystem
metadata bitmaps, however today this approach might hit its limits with
todays huge data storage devices, because of its memory utilization.
Bitarrays stores bitmaps as ..well, as bitmaps. But this is in most
cases highly unefficient because we need to allocate memory even for the
big parts of bitmaps we will never use, resulting in high memory
utilization especially for huge filesystem, when bitmaps might occupy
gigabytes of space.
This commit adds another backend to store bitmaps. It is based on
rbtrees and it stores just used extents of bitmaps. It means that it can
be more memory efficient in most cases.
I have done some limited benchmarking and it shows that rbtree backend
consumes approx 65% less memory that bitarray on 312GB filesystem aged
with Impression (default config). This number may grow significantly
with the filesystem size, but also it may be a lot lower (even negative)
if the inodes are very fragmented (need more benchmarking).
This commit itself does not enable the use of rbtree backend.
[ Simplified the code by avoiding unneeded memory allocation and
deallocation of del_ext. In addition, fixed a bug discovered by the
tst_bitmaps tests: rb_unamrk_bmap() must return true if the bit was
previously set in bitmap, and zero otherwise -- tytso ]

Shorten compile commands run by the build system
The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and
this was starting to cause some tools heartburn. It also made "make
V=1" almost useless, since trying to following the individual commands
run by make was lost in the noise of all of the defines.
So fix this by putting the configure-generated defines in lib/config.h
and the directory pathnames to lib/dirpaths.h.
In addition, clean up some vestigal defines in configure.in and in the
Makefiles to further shorten the cc command lines.

libext2fs: teach bitmap functions about bigalloc/cluster
This patch makes the following changes:
* ext2fs_allocate_block_bitmap() now allocates a bitmap with cluster
granularity for bigalloc file systems. For mke2fs and e2fsck, a
newly added function, ext2fs_allocate_subcluster_bitmap() allocates
a bitmap with block granularity (even for bigalloc file systems).
The newly added function ext2fs_get_bitmap_granularity() will return
the number of bits (log2) of the granularity used by the bitmap.
* The ext2fs_{mark,unmark,test}_block_bitmap2() functions will shift
their passed-in argument by log2(cluster_ganularity) bits right.
This means that the arguments for the single-argument bitmap
functions will be interpreted with block granluarity, since this
minimizes code changes in the rest of the code base.
* The ext2fs_{get,set}_block_bitmap_range() functions will interpret
their arguments in cluster granularity. This is a bit inconsistent,
but the caller of those functions will need to be taught about the
subtleties of clusters for bigalloc file systems.
