Implement a -v option to usbconfig(8), as a shortcut for the most

While here, implement a real -h option that has been promised by the
man page.

Use <sysexits.h> to declare the utility return codes.

usbconfig: use getopt(3) for option handling

This makes option handling consistent with other utilities as well as
Posix rules. By that, it's no longer important whether option name and
its argument are separated by a space or not, so -d5.3 works the same
as -d 5.3.

Also, recognize either /dev/ugen or ugen as prefix to the -d argument.

Note that this removes the undocumented feature that allowed to
specify multiple -d n.m options interleaved with commands referring to
that particular device in a single run.

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.
