Move all the header files that are shared with userspace into
libxfs. This is done as one big chunk simpy to get it done quickly.

Conflicts:
fs/xfs/xfs_trans_resv.c
- fix for XFS_INODE_CLUSTER_SIZE macro removal

tr_swrite is never used, remove it.
From a very quick look, I think the usage of it (and its ancestor
XFS_SWRITE_LOG_RES) went away in commit 13e6d5cd "xfs: merge fsync
and O_SYNC handling" back in 2009.

Add two functions xfs_create_tmpfile() and xfs_vn_tmpfile()
to support O_TMPFILE file creation.
In contrast to xfs_create(), xfs_create_tmpfile() has a different
log reservation to the regular file creation because there is no
directory modification, and doesn't check if an entry can be added
to the directory, but the reservation quotas is required appropriately,
and finally its inode is added to the unlinked list.
xfs_vn_tmpfile() add one O_TMPFILE method to VFS interface and directly
invoke xfs_create_tmpfile().

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.

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.

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.

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.

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.
