9e6461a2d8 Add an xpt_rescan function and a thread that will field
rescan requests. The purpose of this is to allow a SIM
(or other entities) to request a bus rescan and have it
then fielded in a different (process) context from the
caller.

There are probably better ways to accomplish this, but
it's a very small change that helps solve a number of
problems.

59398f700e Remove CTS_SPI_FLAGS_TAG_ENB. Nobody is using it and at least one
author can't remember why it was there.

The CTS_SCSI_FLAGS_TAG_ENB remains in place, and makes sense, and is
checked all over the place.

The CTS_SPI_FLAGS_TAG_ENB was probably an attempt to distinguish
protocol and transport tag capabilities. At the very least this can
be confusing and prone to many bugs, so let's just assume that the
transport tag case just flows from the protocol (and vice versa)
for now.

fa9ed86506 The first of 3 major steps to move the CAM layer forward to using
the CAM_NEW_TRAN_CODE that has been in the tree for some years now.

This first step consists solely of adding to or correcting
CAM_NEW_TRAN_CODE pieces in the kernel source tree such
that a both a GENERIC (at least on i386) and a LINT build
with CAM_NEW_TRAN_CODE as an option will compile correctly
and run (at least with some the h/w I have).

After a short settle time, the other pieces (making
CAM_NEW_TRAN_CODE the default and updating libcam
and camcontrol) will be brought in.

This will be an incompatible change in that the size of structures
related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change
in both size and content. However, basic system operation and
basic system utilities work well enough with this change.

73cf209ffb Put a bit of hysteresis into both BUSY SCSI status returns
and CAM_RESRC_UNAVAIL returns. Delay a tunable amount for
either between retries.

This came up because the MPT IOC was returning "IOC out of
resources" for some user and this caused a CAM_RESRC_UNAVAIL
return. Putting a bit of delay between retries helped them
out.

There was some discussion that an async event should be used
to clear CAM_RESRC_UNAVAIL. That's probably a better notion
eventually.

42cb6a80b6 Implement 'camcontrol reportluns'. This allows users to send the SCSI
REPORT LUNS command to a device.

camcontrol.[c8]:	Implement reportluns.  This tries to print the LUNs
			out in a reasonable format.  Only the periph
			addressing method has been tested, since very little
			hardware that I know of supports the other methods.

scsi_all.[ch]:		Revamp the report luns CDB structure and helper
			functions.  This constitutes a little bit of an API
			change, but since the old CDB length was 10 bytes,
			and the REPORT LUNS CDB length is actually 12 bytes,
			it's clear that no one was using this API in the
			first place.

c1c3139ed3 Add PIM_SEQSCAN for HBA misc flags and code that understands
what to do with it.

This forces us to scan targets sequentially, not in parallel.
The reason we might want to do this is that SPI negotiation
might not work right at the SIM level if we try to do it
in parallel. We *could* fix this for each SIM where this is
broken, but it's a lot harder to do that when we can simply
ask CAM to probe sequentially.

If PIM_SEQSCAN is not set (default), the original behaviour for
probing is unchanged.

LUN probing is still done in parallel for each target in either
case.

While we're at it, clean up some resource leakage for error
cases.

Basic Queueing model (no Head of Queue or Ordered tags).
