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.

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.

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.

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.
