md: Add in export.h for files using EXPORT_SYMBOL
These files were getting the defines for EXPORT_SYMBOL because
device.h was including module.h. But we are going to put an
end to that. So add the proper export.h include now.

dm snapshot: move cow ref from exception store to snap core
Store the reference to the snapshot cow device in the core snapshot
code instead of each exception store. It can be accessed through the
new function dm_snap_cow(). Exception stores should each now maintain a
reference to their parent snapshot struct.
This is cleaner and makes part of the forthcoming snapshot merge code simpler.

dm snapshot: add allocated metadata to snapshot status
Add number of sectors used by metadata to the end of the snapshot's status
line.
Renamed dm_exception_store_type's 'fraction_full' to 'usage'. Renamed
arguments to be clearer about what is being returned. Also added
'metadata_sectors'.

dm snapshot: rename dm_snap_exception to dm_exception
The exception structure is not necessarily just a snapshot
element (especially after we pull it out of dm-snap.c).
Renaming appropriately.

dm snapshot: move status to exception store
Let the exception store types print out their status through
the new API, rather than having the snapshot code do it.
Adjust the buffer position to allow for the preceding DMEMIT in the
arguments to type->status().
