Remove $FreeBSD$: one-line .c pattern

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

Fix various -Wpointer-compare warnings

This warning (comparing a pointer against a zero character literal
rather than NULL) has existed since GCC 7.1.0, and was recently added to
Clang trunk.

Almost all of these are harmless, except for fwcontrol's str2node, which
needs to both guard against dereferencing a NULL pointer (though in
practice it appears none of the callers will ever pass one in), as well
as ensure it doesn't parse the empty string as node 0 due to strtol's
awkward interface.

spdx: initial adoption of licensing ID tags.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Initially, only tag files that use BSD 4-Clause "Original" license.

RelNotes: yes

Closing fd when it's done

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Remove reference to phy_delay from fwcontrol. Thanks for the catch!

Add fd = -1 after close when we detect the format so that subsequent

Final cleanup of fwcontrol.
NetBSD compatibility
Cleanup errors in usage() display
Finish up error handling via errx/warnx
Generate error on unparsed command line syntax
Change device(devbase) to open into the form /dev/fwX.X

- Import the HEAD csup code which is the basis for the cvsmode work.

Beginning of overhaul of fwcontrol:
- Documentation of send_phy_config()
- cleanup of malloc's() and added error checking throughout
- new capability to iterate over multiple firewire buses
- update usage() display
- cleanup command line parsing to allow out of order switches
- cleanup command line parsing to allow multiple switches per invocation
- cleanup grammar of man page a bit
- add some ranges to the man page to indicate what values are valid

Since fwcontrol's code is the same across 6/7/head this can be
applied to all branches after the MFC period.
