99086aa323 trim: Target SCSI UNMAP command instead of WRITE SAME. 
* The UNMAP command is theoretically much faster, as it can get many block
  ranges instead of just a single range.
* Furthermore, the ATA TRIM command resembles it much better.
* Therefore, fs_trim_data now gets an array of ranges, and we use SCSI UNMAP
  to trim.
* Updated BFS code to collect array ranges to fully support the new
  fs_trim_data possibilities.

ea2fa87219 scsi_cmds.h: added SCSIS_ASC_CAPACITY_DATA_HAS_CHANGED 
* indicates the device data capacity has changed..

4264efcc6b * added definitions for SCSI_OP_VARIABLE_LENGTH_CDB, SCSI_SAI_READ_LONG and SCSI_SAO_WRITE_LONG 
* cleanup

f058886908 * added definitions for SCSI_OP_VERIFY_* op commands 
* added support READ_12/16 and WRITE_12/16 in ata and scsi_periph, this enables read/write on block offsets greater than 2TB

f10a55a632 * ata: added ATADevice::ReadCapacity16() 
* ata: don't fail if lba_sector_count is null and lba48_sector_count is not
* scsi_periph: if ReadCapacity() returns 0xffffffff, use ReadCapacity16() instead
* scsi_disk: use a different computation in the struct geometry computation for bigger disks
Tested successfully with a virtual 10TB hard drive.

3e9b601da1 SCSI: Add struct for READ (16) and WRITE (16) commands 
Based on a SCSI Command Reference Manual by Seagate and Wikipedia.

Tested against OpenSolaris iSCSI target on ppc. It choked on the READ (12) opcode.

0a96e18689 * Added opcode definitions for read/write-16 and the extended "read capacity 16" 
over service-action-in.
* Minor cleanup.
