hexdump(1): Exit gracefully on format strings missing conversion

General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

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.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

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.

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

Add POSIX-style support for multibyte characters to od(1): the 'c'
conversion interprets input bytes as multibyte sequences and displays
printable characters in the area corresponding to their first byte.
The remaining bytes are shown as "**".

ANSIify function definitions.
Add some constness to avoid some warnings.
Remove use register keyword.
Deal with missing/unneeded extern/prototypes.
Some minor type changes/casts to avoid warnings.

Un-deprecate od(1): rename the `deprecated' variable to `odmode', remove the
deprecation warning from the utility and manual page. Since this utility
is required by POSIX, it's not likely to be removed any time soon.

This is leading up to the addition of the P1003.1-2001 -s -A -j -N -t options.

WARNS=2 fixups.

Remove the misnamed `emalloc' and replace its uses with the calloc (along
with error checking) that it actually was.

Use err(3) instead of local redefinition, incorporate `hd' in usage str.
