[XFS] Add parameters to xfs_bmapi() and xfs_bunmapi() to have them report

Browse Source 
the range spanned by modifications to the in-core extent map.  Add
XFS_BUNMAPI() and XFS_SWAP_EXTENTS() macros that call xfs_bunmapi() and
xfs_swap_extents() via the ioops vector. Change all calls that may modify
the in-core extent map for the data fork to go through the ioops vector. 
This allows a cache of extent map data to be kept in sync.
