Unionfs: implement native unionfs_fsync/unionfs_fasync methods
Unionfs is not a block-based file system, but it has to work with both
block-based file systems and non-block-based ones (i.e., when
CONFIG_BLOCK=n). We used to define our ->fsync method to file_fsync, but
that's wrong because file_fsync partially depends on CONFIG_BLOCK=y. And we
didn't define an fasync method: now we have both. Moreover, at best,
file_fsync would have caused unionfs to sync up one lower branch---but as a
fanout file system, we need to sync up all valid lower branches.

Unionfs: mmap fixes to ->writepage/readpage/sync_page
unionfs_writepage: handle true errors differently from
AOP_WRITEPAGE_ACTIVATE conditions returned by lower file systems (such as
tmpfs).
unionfs_readpage: call flush_dcache_page as required.
unionfs_sync_page: don't call grab_cache_page to get the lower page, because
that function does too much and could lead to deadlocks. Instead, call the
lighter-weight find_lock_page.

Unionfs: branch-management bugfix to unionfs_file_revalidate
If we re-opened the file on a different branch than the original one, and
only if this was due to a new branch inserted, then update the mnt counts of
the old and new branches accordingly.
