41d8423f71 Stage 3 of dynamic root support. Make all the libraries needed to run
binaries in /bin and /sbin installed in /lib. Only the versioned files
reside in /lib, the .so symlink continues to live /usr/lib so the
toolchain doesn't need to be modified.

50a7fdaed8 Remove MAINTAINER= lines in the makefiles for camcontrol, iostat, libcam
and libdevstat, since the new way of doing things is to just list
maintainership in src/MAINTAINERS.

Also, remove duplicate entries in src/MAINTAINERS for those utilities.  I
already had entries for them.

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.

96a93c63a8 Implement a new camcontrol function, 'camcontrol format'.
libcam/Makefile:	Add scsi_da.c to libcam for the new
			scsi_format_unit() function.

camcontrol.8:		Update the man page for the new format
			functionality, and take out the examples section
			describing how to do it with 'camcontrol cmd'.

camcontrol.c:		New format functionality.  Note that unlike the
			rest of the camcontrol subcommands, this one is
			interactive by default.  Because of the potential
			destructiveness of the format command, I thought
			it necessary to get confirmation from the user
			before spamming a disk.  You can disable the
			interactive behavior, and the status meter with
			command line arguments.

scsi_da.c:		Add the new scsi_format_unit() cdb building
			function and use #ifdef _KERNEL to make this file
			compile in both the kernel and userland.  The
			format unit function is currently only defined in
			the non-kernel case, because nothing in the kernel
			is using it.  If that changes, it should be
			un-ifdefed and compiled in both cases.

scsi_da.h:		New function declaration, CDB structure and format
			data structures.

Thanks to Nick Hibma for providing some valuable input on these changes.

as a separate line so we can override it on the command line if

01a4eb824c Add man pages for many of the functions in the CAM library. This covers
most of the open/close routines, and the buffer/cdb parsing routines
derived from the old scsi(3) library.

The cam_cdbparse(3) man page borrows from the old scsi(3) man page, so the
copyright and history section reflect that.

The many scsi_* functions and other functions that are pulled in from the
kernel aren't documented yet, but will be eventually.

71bf9f8a93 Remove scsi_da.c from the list of things compiled into the CAM library.
The functions that were being compiled into the library have been moved to
scsi_all.c.

One warning:  Any programs using scsi_start_stop() or scsi_read_write()
              that included scsi_da.h but not scsi_all.h will need to be
              changed to include scsi_all.h.  This doesn't affect
              camcontrol, and I don't think it affects any ports, but you
              never know.
