288699feca xfs: drop dmapi hooks
Dmapi support was never merged upstream, but we still have a lot of hooks
bloating XFS for it, all over the fast pathes of the filesystem.

This patch drops over 700 lines of dmapi overhead.  If we'll ever get HSM
support in mainline at least the namespace events can be done much saner
in the VFS instead of the individual filesystem, so it's not like this
is much help for future work.

efc557570d [XFS] avoid memory allocations in xfs_fs_vcmn_err
xfs_fs_vcmn_err can be called under a spinlock, but does a sleeping memory
allocation to create buffer for it's internal sprintf.  Fortunately it's
the only caller of icmn_err, so we can merge the two and have one single
static buffer and spinlock protecting it.  While we're at it make sure
we proper __attribute__ format annotations so that the compiler can detect
mismatched format strings.

dc74eaad8c [XFS] Prevent buffer overrun in cmn_err().
The message buffer used by cmn_err() is only 256 bytes and some CXFS
messages were exceeding this length. Since we were using vsprintf() and
not checking for buffer overruns we were clobbering memory beyond the
buffer. The size of the buffer has been increased to 1024 bytes so we can
capture these larger messages and we are now using vsnprintf() to prevent
overrunning the buffer size.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
