Add zfs_open()/zfs_close()
In the original implementation the zfs_open()/zfs_close() hooks
were dropped for simplicity. This was functional but not 100%
correct with the expected ZFS sematics. Updating and re-adding the
zfs_open()/zfs_close() hooks resolves the following issues.
1) The ZFS_APPENDONLY file attribute is once again honored. While
there are still no Linux tools to set/clear these attributes once
there are it should behave correctly.
2) Minimal virus scan file attribute hooks were added. Once again
this support in disabled but the infrastructure is back in place.
3) Most importantly correctly handle assigning files which were
opened syncronously to the intent log. Without this change O_SYNC
modifications could be lost during a system crash even though they
were marked synchronous.
