8b1d35bdbb Improve SCSI and SATA trim support
Fixes:
* scsi: Fix a bug that caused the device capacity to be set
  to an undefined value for some large SCSI devices when
  READ CAPACITY (16) was used
* ahci: Fix VPD page reporting so that it does not return
  undefined values
* ahci: Set the write bit to true when sending a DATA SET
  MANAGEMENT (trim) command to a device. The command would
  otherwise fail and time out on some devices.

Improvements:
* scsi: Extend the READ CAPACITY (16) support to also
  include logical block provisioning information
* scsi: Prefer READ CAPACITY (16) over READ CAPACITY (10)
  on devices that are expected to support this command
* scsi, ahci: Enable trim on SCSI and SATA devices that
  are expected to support trim and which correctly report
  trim support
* ahci: Redo the implementation of the SCSI UNMAP command
* scsi: Redo UNMAP-related code
* scsi: Add support for UNMAP via WRITE SAME (10) and
  WRITE SAME (16) commands
* When copying trim ranges between different data types,
  make sure that the values don't change (detect overflows)
* Report the number of trimmed blocks even if the trim
  operation fails

93c0a5d790 Reworked little endian bitfields a bit.
* Added B_ prefix.
* Renamed 16 bit variants to B_LENDIAN16_*.
* Added 32 bit variants (albeit only 16 of them for now).
* Adjusted headers that were using them.

6fd00f80e8 scsi_periph: implemented VPD inquiry.
* declared block limits and logical block provisioning structs.
* based on SPC-4 and SBC-4 standards.

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.

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.
