Changes to device handling;
o Only one list of block devices for all tables
o Locking to ensure that block devices only get opened once
o Block device handling is now in dm-blkdev.c
o We open block devices when we create the tables and hold them open until
the table is destroyed (this prevents the module for the device being
unloaded after table parsing and before the table is used)
o We compute the hardsect size when the table is created rather than when
someone requests it.
Still to fix/change:
o Probably want to hash the device lists in dm-blkdev.c and also remove refs
to struct dm_bdev outside this file.
o Need to ensure that hardsect_size doesn't change when new tables are
swapped in (maybe this ought to be a per volume parameter and the tables
will only parse if they match the value for the volume?).
