There are interfaces that are used by mke2fs.c and tune2fs.c which are
in quotaio.h, and some future changes will be much simpler if we can
combine the two header files together. Also the guard #ifdef for
mkquota.h was incorrect, which caused problems when both header files
needed to be included.
Also remove quota.pc and installation rules for libquota, since this
library is never going to be something that we can export externally
anyway. Eventually we'll want to clean up the interfaces and move the
external publishable interfaces to the libext2fs library, and then
rename what's left from libquota.a to libsupport.a for internal use
only.

We already skip the low dtime check if the number of inods is greater
than the last mount or last written time. However, if a very large
file system is resized sufficiently large that the number of inodes is
greater than when the file system was original created, we can end up
running afoul of the low dtime check. This results in a large number
of false positives which e2fsck can fix up without causing any
problems, but it can induce a large amount of anxiety for the system

The s_desc_size in the superblock specifies the group descriptor
size in bytes, but in various places the EXT4_FEATURE_INCOMPAT_64BIT
flag implies that the descriptor size is EXT2_MIN_DESC_SIZE_64BIT
(64 bytes) instead of checking the actual size. In other places,
the s_desc_size field is used without checking for INCOMPAT_64BIT.
In the case of ext2fs_group_desc() the s_desc_size was being ignored,
and assumed to be sizeof(struct ext4_group_desc), which would result
in garbage for any but the first group descriptor. Similarly, in
ext2fs_group_desc_csum() and print_csum() they assumed that the
maximum group descriptor size was sizeof(struct ext4_group_desc).
Fix these functions to use the actual superblock s_desc_size if
INCOMPAT_64BIT.
Conversely, in ext2fs_swap_group_desc2() s_desc_size was used
without checking for INCOMPAT_64BIT being set.
The e2fsprogs behaviour is different than that of the kernel,
which always checks INCOMPAT_64BIT, and only uses s_desc_size to
determine the offset of group descriptors and what range of bytes
to checksum.
Allow specifying the s_desc_size field at mke2fs time with the
"-E desc_size=NNN" option. Allow a power-of-two s_desc_size
value up to s_blocksize if INCOMPAT_64BIT is specified. This
is not expected to be used by regular users at this time, so it
is not currently documented in the mke2fs usage or man page.
Add m_desc_size_128, f_desc_size_128, and f_desc_bad test cases to
verify mke2fs and e2fsck handling of larger group descriptor sizes.

Add a LOG2_CHECK mode for check_super_value() so that it is easy
to verify values that are supposed to be power-of-two values
(s_desc_size and s_inode_size so far). In ext2fs_check_desc()
also check for a power-of-two s_desc_size.
Print out s_desc_size in debugfs "stats" and dumpe2fs output, if
it is non-zero.
It turns out that the s_desc_size validation in check_super_block()
is not currently used by e2fsck, because the group descriptors are
verified earlier by ext2fs_check_desc(), and even without an
explicit check of s_desc_size the group descriptors fail to align
correctly on disk. It makes sense to keep the check_super_block()
regardless, in case the code changes at some point in the future.

When the rehash process is running on a bigalloc filesystem, it
compresses all the directory entries and hash structures into the
beginning of the directory file and then uses block_iterate3() to free
the blocks off the end of the file. It seems to call
ext2fs_block_alloc_stats2() for every block in a cluster, which is
unfortunate because this function allocates and frees entire clusters
(and updates the summary counts accordingly). In this case e2fsck

When we're rehashing directories, it's possible that an extent block
(or a map block) could be (silently) allocated by the underlying
libext2fs when expanding the directory. This silent allocation is not
captured in block_found_map, which is disastrous if later the rehash
process expands another directory and uses that same block from
before without realizing that it's now in use.
Therefore, if we notice that the free block count has dropped by more
than what e2fsck allocated itself during the expansion, we iterate the
directory's blocks a second time to ensure that these silent
allocations are marked in the found blocks bitmap.

because the file size is not increased when FALLOC_FL_KEEP_SIZE is
