1de7b4b805 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.

3b2bb13317 Make it possible for operations to refer to GPIO pins by name
- 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

d752f0f69d Add a new ioctl to allow the setting of GPIO pin names.
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.

22e3858c24 Assume that the -f argument is /dev/gpioc0 if it is not passed.
hrs@ provided this verison of the patch and showed me where all the needed
changes were to be made outside of gpioctl.c

bf70becee6 More -Wmissing-variable-declarations fixes.
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.
- sbin/camcontrol: Move `verbose' into camcontrol.h and fix shadow warnings.
- usr.bin/calendar: Remove unneeded variables.
- usr.bin/chat: Make `line' local instead of global.
- usr.bin/elfdump: Comment out unneeded function.
- usr.bin/rlogin: Use _Noreturn instead of __dead2.
- usr.bin/tset: Pull `Ospeed' into extern.h.
- usr.sbin/mfiutil: Put global variables in mfiutil.h.
- usr.sbin/pkg: Remove unused `os_corres'.
- usr.sbin/quotaon, usr.sbin/repquota: Remove unused `qfname'.
