Change the way the plex lock mutexes work. Previously they were part

of the struct plex, which tore apart the mutex linked lists when the
plex table was expanded.  Now we maintain a pool of mutexes (currently

update_volume_config: Remove redundant diskconfig parameter.

expand_table: Add parameters file and line if we're debugging.
