peter 6994e5b801 More cleanups, tweaks and features.
- make this work:   options FOO123=456   *without quotes*
- grumble (but accept) vector xxxintr, and tty/net/bio/cam flags.
- complain if a device is specified twice (eg: 2 x psm0)
- don't require quotes around:  port IO_COM2
- recognize negative numbers.  (ie: options CAM_DEBUG_UNIT=-1)
- GC some more unused stuff (we don't have composite disks from config(8)).
- various other nits (snprintf paranoia etc)
