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.

dconschat(8): Use NULL instead of 0 for the last argument in execl(3)

Found while experimenting with the gcc sentinel attribute.

Fix the following warning from clang trunk:

usr.sbin/dconschat/dconschat.c:163:65: error: format specifies type 'size_t' (aka 'unsigned int') but the argument has type 'off_t' (aka 'long long') [-Werror,-Wformat]
snprintf(buf, PAGE_SIZE, "\r\n[dconschat reset target(addr=0x%zx)...]\r\n", dc->reset);
~~^ ~~~~~~~~~
%llx

Silence this by casting dc->reset to intmax_t, and using the appropriate
length modifier. While here, wrap the line to a 80 character margin.

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.

Include <sys/wait.h> and <signal.h> for wait() and kill().

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

Set the default escape character as described in the manpage of dconschat(8).
Fix a cut-and-paste error.

- Make target reset work on telnet port.
- Add a key bind to invoke kgdb on the terminal. (experimental)

Reset dc->paddr and dc->reset if we cannot read configuration ROM.

Clean up escape sequence handling and add support for
resetting target and suspending dconschat.

Add heuristics for smooth reconnection.

Discard backlog on GDB port when connected.
