Add reading of supported opcodes and their timeouts
at attachment time. Though this information is optional,
it allows to override our fixed timeouts with device
provided timeouts. These timeouts will override the
hardcoded values if the device provided timeouts
exceed the hardcoded values and are less than a day.

Using the device provided timeouts avoids premature
device resets and unreliable operation due to
inadequate timeouts.

Due to the limited implementations of USB
umass devices this feature is disabled for all
umass attached devices.

Part 1 of a cleanup pass over the SCSI subsystem. The aim is to name
everything "scsi_*", since we really are talking about the SCSI command
set, ATAPI transport not withstanding. Improve the names of many structures,
and prepend "SCSI_" onto all SCSI command opcodes. Place items described
by the SCSI Primary Commands document into scsi_spc.h.
