GPIO drivers who supports interrupts report them in the caps
(obtain via the getcaps method) but gpioctl doesn't know
how to interpret this and print "UNKNOWN" for each one of them.
Even if we don't have userland gpio interrupts support for now
let gpioctl print the supported caps.

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.
- Try to guess what is provided as a pin spec for -t or for get/set
operation: number or name. Fails in case of ambiguity.
- Add -p and -N switches to force pin specification interpretation:
-p forces spec to be pin number, -N forces it to be name

When a gpiobus child is added, use its name to identify the mapped pin
names.
Make the respective changes to libgpio.
Add a new '-n' flag to gpioctl(8) to set the pin name.

In addition to adding `static' where possible:
- bin/date: Move `retval' into extern.h to make it visible to date.c.
- bin/ed: Move globally used variables into ed.h.
