Module Name:    src
Committed By:   xtraeme

Modified Files:
        src/sys/dev: bio.c biovar.h

Log Message:
Improve the bio(4) API for incoming changes to arcmsr(4) (and perhaps
other drivers in the future):

- Added BIOC_SVCHECKING to the BIOCVOL ioctl, to know if a volume is
  running a consistency check.
- Added three more volume levels for the BIOCVOL ioctl.
- Added BIOC_SDPASSTHRU to the BIOCDISK ioctl, to know if a disk is
  in pass-through mode.
- Added BIOCDISK_NOVOL; it's used with the same reason than BIOCDISK,
  but it's used only to get information about the physical disks connected
  in a controller (regardless if they are in a volume set or not).
- Added BIOC_SSDELHOTSPARE, BIOC_SSPASTHRU, BIOC_SSDELPASSTHRU,
  BIOC_SSCHECKSTART_VOL and BIOC_SSCHECKSTOPVOL; to remove a hot-spare,
  add and remove a pass-through disk and to start/stop a consistency
  check in a volume.
- Added the BIOC_VOLOPS ioctl; to create/remove a volume set.
- Removed the BIOCCREATERAID ioctl, it was too limited for my needs.
- Added compatibility ioctls for BIOCDISK and BIOCVOL, enabled via COMPAT_30.
