Rework pagebuf_delwri_flush to be list safe Rework the global list handling of pbd_delwrite_queue. We were dropping the list lock while scanning the list while starting pagebuf IO, which could lead to an inconsistent list. Change the code to scan the list looking for all pagebuf's that can be flushed placing them on a local temporary list. Then walk the temporary list NOT under the global lock firing off IO and subsequently waiting for IO to finish if told to so.

Rework how IO completion is handled in pagebuf, particularly the case of blocksizes less than the pagesize. This makes more of an effort to set pages uptodate in this case, and removes the page_sync_t structure from the code entirely (previously we were allocating one of these per-page for small IOs). Some of the functions no longer need to return errors now, and some were doing bytes-written accounting unnecessarily - no more.

Contributed fix from ASANO Masahiro <masano@tnes.nec.co.jp>, for the case where we are going to get multiple I/O completions from the driver under pagebuf, set the expected completion count in one go rather than incrementing it as we submit requests. Otherwise we can get multiple I/O completions which get treated as the last one. set psync->remain in one go rather than incrementing it several times.

initial attempt at supporting multiple block sizes on the metadata path. lots of new code which is only executed for non-pagesized filesystems, so should be no change for pagesize case. had to move a few chunks of code around to allow some bit sharing, but shouldn't be any ill side-effects.

Prepare pagebuf APIs for multiple blocksize support. In particular, the IO path needs to get access to blocksize information which currently is only held in the xfs_mount structure -- this change reorganises a few things so that the necessary information is available to the code that needs it. We also no longer need pbm_dev field (pb_bmap_t) as this is now available from pb_target_t always.
