MFC r326276:

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

The original programs that this code was lifted from (pccardd and
pccardc) parsed data to make decisions about stuff related to card
configuration.

The purely CIS dumping aspect of this program obviates the need for
such parsing. Save some space and don't parse the data anymore for
configuration purposes. Just parse it to print an interpreatation of
it.

dump() really is unused, so retire it.

Simplify: move dumpcis.c and dumpcisfile.c into main.

make this warns=5 clean

Move dumpcis to its own directory, start to decouple from the
pccardc/pccardd history.

Add a new subcommand to pccardc(8), "dumpcisfile", which reads a CIS
structure from a file instead of a PC-CARD itself before parsing and
dumping it. (E.g. useful when you get a CIS file from a manufacturer
which fixes they broken card's CIS, and add it to the pccard quirks.)

Add some code which read manufucturer id. This is for NEWCARD compatibility.

MFPAO3. Improvement of of pccard cis tuple parsing capability.
- Fixed bogus CIS tuple dumping (Network node ID, IRQ modes and etc.)
- Include telling drivers ethernet address if Network node ID
tuple is available. This is usefull for some bogus ehter cards which
can't get correct ethernet address from CIS tupple.

Bump CIS_MAXSTR from 30 to 254. pccard appears to define the entire
section we take them from to be up to 255 bytes long, so that's the
max size for the string. They can't all be this big, but I don't have
a better number and better to be a little long than a little short.

Also only consume len characters of the cis buffer so we don't run off
the end into the next buffer and get garbage. This second patch
shouldn't impact anything, but I'll hold off back porting this to
-stable until I get more reports on the stability before/after this
fix.

$Id$ -> $FreeBSD$

- Bump up the size of the space for strings read from PCMCIA cards. Newer
cards have longer entries.

Submitted by: Lars Fredriksen <lars@fredriks-1.pr.mcs.net>

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Staticize and remove unused function.

Inspired by: The Nomad code

- Removed dead code (if you need it you can get it out of the
Repository).
- Added some comments, and moved some code around to make flow more
obvious.

No functional changes.

Prepend the CIS string length define with CIS_ per the rest of the
constants.

Added RCS Id and BSD-style copyrights to individual files.

Run indent on all these files to make them more readable. (I also went
through by hand and cleaned up some indent bogons.)

The userland part of Andrew McRae's PCMCIA/PCCARD code.

This is not quite finished yet, and therefore I have not added it to the
usr.sbin/Makefile yet.
I collected a bunch of Andrews small programs into one: pccardc /phk
