o Kill write funcs for error/status files
...
o Redo write logic for table file
o Relax rules for symlink content by removing the rewriting function
Well I probably won't get a chance to work on this tomorrow, so this is my
changeset to date.

Well when things start looking so complicated that future direction becomes
...
non-obvious, its time to simplify :-)
o Moving towards a simpler and more obviously correct interface
o Removed some fs operations in directories representing volumes
o Changed some file names
o Made things cleaner
more changes to follow...

o Changed dm_create() to return a struct mapped_device rather than an int
...
o Changed dm_remove() to accept a struct mapped_device argument rather than
a name
o We no longer have to look up devices by name, the dcache handles that
nicely for us
o Fixed a bug where we were freeing a structure before we'd finished with
it.
o The name field in struct mapped_device is now only used in a very few
places in dm.c and will be replaced in future with a back reference to
the dentry rather than keeping the name in two places.

o New file dmfs-super.c
...
o dmfs-dir.c becomes dmfs-lv.c
o dmfs-file.c becomes dmfs-table.c
o A few tweeks and updates
The main reason for the slow progress on these files (which are not yet used
by the device mapper) is that we are working out what this interface should
look like as we go along.
Once this has evolved a bit further and in a state where it can be used we'll
announce it on the lists for further comment.
