This series follows up on conversions about relogging infrastructure
and the way xfs_log_done() does two things but only one of several
callers uses both of those functions. It also pointed out that
xfs_trans_commit() never writes to the log anymore, so only
checkpoints pass a ticket to xlog_write() with this flag set and
no transaction makes multiple calls to xlog_write() calls on the
same ticket. Hence there's no real need for XLOG_TIC_INITED to track
whether a ticket has written a start record to the log anymore.
A lot of further cleanups fell out of this. Once we no longer use
XLOG_TIC_INITED to carry state inside the write loop, the logic
can be simplified in both xlog_write and xfs_log_done. xfs_log_done
can be split up, and then the call chain can be flattened because
xlog_write_done() and xlog_commit_record() are basically the same.
This then leads to cleanups writing both commit and unmount records.
Finally, to complete what started all this, the XLOG_TIC_INITED flag
is removed.

Changes since v1:
- taking this over from Dave (for now) as he is still injured, an it
interacts closely with my log error handling bits
- rebased on top of for-next + the "more log cleanups" series
- fix an accounting error in xlog_write
- use a bool for the ticket header in xlog_write
- add a new patch to split xlog_ticket_done
