give_sd_to_plex: Don't set Raid-5 subdisk state here.
config_subdisk: handle the name parameter correctly when the subdisk
was referenced in a previous plex definition. The
name parameter must come first.
Handle autosizing relatively correctly. There is
still a danger of losing drive space if problems
occur with an autosized subdisk.
Set state to empty, not up, when complete. This also
solves a nagging problem about enforcing the need to
initialize RAID-5 plexes.
config_plex: handle the name parameter correctly when the plex
was referenced in a previous volume definition. The
name parameter must come first.
Handle initial state better.
update_plex_config:
Calculate the trim factor for RAID-5 plexes correctly.
Set the number of down subdisks correctly when reading
from disk config.
