3d3c8b5222 xfs: refactor xfs_trans_reserve() interface
With the new xfs_trans_res structure has been introduced, the log
reservation size, log count as well as log flags are pre-initialized
at mount time.  So it's time to refine xfs_trans_reserve() interface
to be more neat.

Also, introduce a new helper M_RES() to return a pointer to the
mp->m_resv structure to simplify the input.

783cb6d172 xfs: Make writeid transaction use tr_writeid
tr_writeid is defined at mp->m_resv structure, however, it does not
really being used when it should be..

This patch changes it to tr_writeid to fetch the correct log
reservation size.

20996c9326 xfs: Introduce tr_fsyncts to m_reservation
A preparation step.

For now fsync_ts transaction use the pre-calculated log reservation
size of tr_swrite.  This patch introduce a new item tr_fsyncts to
mp->m_reservations structure so that we can fetch the log
reservation value for it in a same manner to others.

0eadd10288 xfs: Introduce a new structure to hold transaction reservation items
Introduce a new structure xfs_trans_res to hold transaction
reservation item info per log ticket.

We also need to improve xfs_trans_resv_calc() by initializing the
log count as well as log flags for permanent log reservation.

7fd36c4418 xfs: split out transaction reservation code
The transaction reservation size calculations is used by both kernel
and userspace, but most of the transaction code in xfs_trans.c is
kernel specific. Split all the transaction reservation code out into
it's own files to make sharing with userspace simpler. This just
leaves kernel-only definitions in xfs_trans.h, so it doesn't need to
be shared with userspace anymore, either.
