3d438ad61f Remove 'register' keyword.
It does not help modern compilers, and some may take some hit from it.
(I also found several functions that listed *every* of its 10 local vars with
 "register" -- just how many free registers do people think machines have?)

075828a91a Well, RELEASE_BUILD_FIXIT has now been renamed into RELEASE_CRUNCH.
At least, the old version is still good for the MFC though (where
everything is still going the old way). ;-)

5710d224b6 Add 'camcontrol rescan all' and 'camcontrol reset all' functionality to
camcontrol.

This enables rescanning all busses or resetting all busses in a system.
The current implementation is not the ideal way to do it -- the ideal way
to do it would be for the transport layer to handle wildcarded busses on
bus rescan and reset operations.  The current implementation enumerates all
the busses and sends a rescan or reset CCB individually.  Handling this
behavior in the transport layer will happen later.

3393f8daa3 Rewrite of the CAM error recovery code.
Some of the major changes include:

	- The SCSI error handling portion of cam_periph_error() has
	  been broken out into a number of subfunctions to better
	  modularize the code that handles the hierarchy of SCSI errors.
	  As a result, the code is now much easier to read.

	- String handling and error printing has been significantly
	  revamped.  We now use sbufs to do string formatting instead
	  of using printfs (for the kernel) and snprintf/strncat (for
	  userland) as before.

	  There is a new catchall error printing routine,
	  cam_error_print() and its string-based counterpart,
	  cam_error_string() that allow the kernel and userland
	  applications to pass in a CCB and have errors printed out
	  properly, whether or not they're SCSI errors.  Among other
	  things, this helped eliminate a fair amount of duplicate code
	  in camcontrol.

	  We now print out more information than before, including
	  the CAM status and SCSI status and the error recovery action
	  taken to remedy the problem.

	- sbufs are now available in userland, via libsbuf.  This
	  change was necessary since most of the error printing code
	  is shared between libcam and the kernel.

	- A new transfer settings interface is included in this checkin.
	  This code is #ifdef'ed out, and is primarily intended to aid
	  discussion with HBA driver authors on the final form the
	  interface should take.  There is example code in the ahc(4)
	  driver that implements the HBA driver side of the new
	  interface.  The new transfer settings code won't be enabled
	  until we're ready to switch all HBA drivers over to the new
	  interface.

src/Makefile.inc1,
lib/Makefile:		Add libsbuf.  It must be built before libcam,
			since libcam uses sbuf routines.

libcam/Makefile:	libcam now depends on libsbuf.

libsbuf/Makefile:	Add a makefile for libsbuf.  This pulls in the
			sbuf sources from sys/kern.

bsd.libnames.mk:	Add LIBSBUF.

camcontrol/Makefile:	Add -lsbuf.  Since camcontrol is statically
			linked, we can't depend on the dynamic linker
			to pull in libsbuf.

camcontrol.c:		Use cam_error_print() instead of checking for
			CAM_SCSI_STATUS_ERROR on every failed CCB.

sbuf.9:			Change the prototypes for sbuf_cat() and
			sbuf_cpy() so that the source string is now a
			const char *.  This is more in line wth the
			standard system string functions, and helps
			eliminate warnings when dealing with a const
			source buffer.

			Fix a typo.

cam.c:			Add description strings for the various CAM
			error status values, as well as routines to
			look up those strings.

			Add new cam_error_string() and
			cam_error_print() routines for userland and
			the kernel.

cam.h:			Add a new CAM flag, CAM_RETRY_SELTO.

			Add enumerated types for the various options
			available with cam_error_print() and
			cam_error_string().

cam_ccb.h:		Add new transfer negotiation structures/types.

			Change inq_len in the ccb_getdev structure to
			be "reserved".  This field has never been
			filled in, and will be removed when we next
			bump the CAM version.

cam_debug.h:		Fix typo.

cam_periph.c:		Modularize cam_periph_error().  The SCSI error
			handling part of cam_periph_error() is now
			in camperiphscsistatuserror() and
			camperiphscsisenseerror().

			In cam_periph_lock(), increase the reference
			count on the periph while we wait for our lock
			attempt to succeed so that the periph won't go
			away while we're sleeping.

cam_xpt.c:		Add new transfer negotiation code.  (ifdefed
			out)

			Add a new function, xpt_path_string().  This
			is a string/sbuf analog to xpt_print_path().

scsi_all.c:		Revamp string handing and error printing code.
			We now use sbufs for much of the string
			formatting code.  More of that code is shared
			between userland the kernel.

scsi_all.h:		Get rid of SS_TURSTART, it wasn't terribly
			useful in the first place.

			Add a new error action, SS_REQSENSE.  (Send a
			request sense and then retry the command.)
			This is useful when the controller hasn't
			performed autosense for some reason.

			Change the default actions around a bit.

scsi_cd.c,
scsi_da.c,
scsi_pt.c,
scsi_ses.c:		SF_RETRY_SELTO -> CAM_RETRY_SELTO.  Selection
			timeouts shouldn't be covered by a sense flag.

scsi_pass.[ch]:		SF_RETRY_SELTO -> CAM_RETRY_SELTO.

			Get rid of the last vestiges of a read/write
			interface.

libkern/bsearch.c,
sys/libkern.h,
conf/files:		Add bsearch.c, which is needed for some of the
			new table lookup routines.

aic7xxx_freebsd.c:	Define AHC_NEW_TRAN_SETTINGS if
			CAM_NEW_TRAN_CODE is defined.

sbuf.h,
subr_sbuf.c:		Add the appropriate #ifdefs so sbufs can
			compile and run in userland.

			Change sbuf_printf() to use vsnprintf()
			instead of kvprintf(), which is only available
			in the kernel.

			Change the source string for sbuf_cpy() and
			sbuf_cat() to be a const char *.

			Add __BEGIN_DECLS and __END_DECLS around
			function prototypes since they're now exported
			to userland.

kdump/mkioctls:		Include stdio.h before cam.h since cam.h now
			includes a function with a FILE * argument.

7e32b20d95 This is an overhaul of the mode page handling in camcontrol as well as
related patches. These include:
	* Mode page editting can be scripted. This involves two
	  things: first, if stdin is not a tty, changes are read from
	  stdin rather than invoking $EDITOR. Second, and more
	  importantly, not all modepage entries must be included in the
	  change set. This means that camcontrol can now gracefully handle
	  more intrusive editting from the $EDITOR, including removal or
	  rearrangement of lines. It also means that you can do stuff
	  like:
		# echo "WCE: 1" | camcontrol modepage da3 -m 8 -e
		# newfs /dev/da3
		# echo "WCE: 0" | camcontrol modepage da3 -m 8 -e
	* Range-checking on user-supplied input values. modeedit.c now
	  uses the field width specifiers to determine the maximum
	  allowable value for a field. If the user enters a value larger
	  than the maximum, it clips the value to the max and warns the
	  user. This also involved patching cam_cmdparse.c to be more
	  consistent with regards to the "count" parameter to arg_put
	  (previously is was the length of strings and 1 for all integral
	  types). The cam_cdbparse(3) man page was also updated to reflect
	  the revised semantics.
	* In the process, I removed the 64 entry limit on mode pages (not
	  that we were even close to hitting that limit). This was a nice
	  side-effect of the other changes.
	* Technically, the new mode editting functionality allows editting
	  of character array entries in mode pages (type 'c' or 'z'),
	  however since buff_encode doesn't grok them it is currently
	  useless.
	* Camcontrol gained two new options related to mode pages: -l and
	  -b. The former lists all available mode pages for a given
	  device. The latter forces mode page display in binary format
	  (the default when no mode page definition was found in
	  scsi_modes).
	* Added support for mode page names to scsi_modes. Allows names to
	  be displayed alongside mode numbers in the mode page
	  listing. Updated scsi_modes to use the new functionality. This
	  also adds the semicolon into the scsi_modes syntax as an
	  optional mode page definition terminator. This is needed to name
	  pages without providing a page format definition.
	* Updated scsi_all.h to include a structure describing mode page
	  headers.
	* Added $FreeBSD$ line to scsi_modes.

9f4285439a When printing out the transfer rate display for 'camcontrol inquiry',
use the current setting for tagged queueing when deciding whether or not to
print "Tagged Queueing Enabled" instead of using the device's actual
capabilities.

This is more consistent with the rest of the transfer rate display, which
relies on current settings, and is more consistent with the way we display
things on boot.

955f7e7474 Fix 'camcontrol inquiry'. The inquiry data structure changes (increased to
256 bytes) caused it to break on many devices.

The SCSI spec says that for commands with 8-bit length fields, a value of 0
means 256 bytes.  As it turns out, many devices don't deal with that
properly.  Some interpret the 0 as 0, and return no data.  Others return
more than 256 bytes of data, and cause an overrun.

The fix is to tell the device we've only allocated SHORT_INQUIRY_LENGTH (36
bytes) of inquiry data, instead of sizeof(struct scsi_inquiry_data).

camcontrol.c:		Change inq_len in the call to scsi_inquiry() to
			SHORT_INQUIRY_LENGTH, and add a long comment
