Bring the libxfs headers and code into sync with the 2.6.37 kernel code.
Update the rest of xfsprogs to work with the new code.
Note: this does not convert xfsprogs to the kernel xfs_trans_ijoin\ijoin_ref
interface, it maintains the older ijoin/ihold interface because of the
different way the inode reference counting works in libxfs. More work will be
needed to change it over to a manner compatible with the current kernel API.
Note: log sector size handling needs to be sorted out. Specifically,
initialising l_sectbb_log/l_sectBBsize correctly and removing the hacks in
xlog_bread and friends (libxlog/xfs_log_recover.c) to work around the fact they
are not initialised correctly. (FWIW, I don't think xfsprogs handles large log
sector size correctly as a result, and especially not if the log device sector
size is different to the data device sector size).
Testing:
Currently passes xfstests on x86_64 w/ 4k block sizes and 512 byte block/2k
directory block filesystems. No obvious regressions are occurring during
xfstests runs.
