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
