vinumopen: add code to open raw subdisks. This is now used to

initialize subdisks.  Probably the plex-related subdisk type will die
a death.

vinumconfig.c:

Accept (and ignore) kernel state information in userland config
files.  This saves a lot of error recovery and also makes it possible
to use the output of printconfig to create new configuration.

Remove checkdiskconfig().  It wasn't needed any more.

Start adding support for hot spare drives.  You can't put anything on
them (yet).

Change message formats from %lld to %qd.

get_empty_sd: Initialize size to -1.  Previously this was done in
config_subdisk, which is the wrong place.

start_config: set current drive, plex and volume to -1, thus stopping
  update configurations from taking their defaults from old configs.
