add option to make_ext4fs to record blocks for each file
Add the -B option to make_ext4fs, which causes it to record the block
ranges used for each (regular) file in the image. We can use this
information to construct more efficient block-based incremental OTAs.

make_ext4fs: fix block allocation to be best-fit
The block allocation algorithm was failing to allocate parts of large
files out of partially filled block groups. Update the allocation
algorithm to be a simpler best fit loop - if the remaining length to
allocate is larger than any single contiguous region, allocate the
largest single contiguous region and continue allocating, otherwise
allocate the smallest contiguous that can hold the length.

ext4_utils: move sparse file pointer out of fs_info
Move the sparse file pointer out of the fs_info struct in
preparation for exporting fs_info without sparse file support.

ext4_utils: refactor kernel headers
Move the kernel header includes into a single include file that
can deal with getting the kernel int types correct on all
platforms.

Avoid underflow on an unsigned int when computering bg overrun
A computation for when a block group overruns the end of an image
was consistently storing a negative number in an unsigned var,
and then checking for >0, which is always true for negative numbers.
So first check if the number will be positive before computing it.

ext4_utils: add filesystem capabilities support.
Add support for specifying filesystem capabilities when
creating a new filesystem.
The combination of SELinux extended attributes plus
filesystem capability extended attributes is too big
to fit inside one inode entry. Because of this, I added
support to ext4_utils to create an xattr block and link
the inode to that block. We continue to try to fit
everything inside the inode if possible, but fall over to
creating a block if the extended attribute is too big.

ext4_utils: mark uninitialized inode tables in block groups
Block groups that have no used inodes have their inode table left
uninitialized, unless -t is specified, in which case they are
explicitly zeroed. When they are uninitialized, writing a sparse
ext4 image over existing data can cause e2fsck to confuse the
uninitialized data for lost inodes.
Set the EXT4_BG_INODE_UNINIT flags on block groups that have no
used inodes. This flag requires the block group checksum feature
to be enabled, so also enable the checksum feature in the superblock
and compute the checksum for the block group.
Since zeroing the inode tables is now useless, remove the code for
it and deprecate the -t command line option.

Refactor sparse file support into libsparse
Minimal refactoring of output_file.c into libsparse in preparation
for completely separating libsparse from ext4_utils.
Moves output_file.c, backed_block.c, and parts of ext4_utils.c
into libsparse. The only changes to the remanining files in
ext4_utils are using the new sparse.h header, and moving the
wipe call out of output_file.c and into make_ext4fs.c.

Bug fixes to make_ext4fs
Fix definition of uuid struct.
Properly set the block_group number in each backup copy of the superblock.
Adjust the info.total_inodes field after rounding up the inodes per block group.
Add the option -t to initialize all the inode tables. If also specified with
the -s option, use the CHUNK_TYPE_FILL sparse records to initialize them.
