This update makes this driver more than just an example and allows for:
o More than one pin to be attached to a gpioirq instance. That is,
the mask parameter can be greater than 0x01 now.
o A /dev/gpioirqN device that allows GPIO pin interrupts to be
transported into userland. This is a device that can be opened for
reading with a simple fixed output indicating the device unit, pin
number and current pin state.
This update was used as part of a physical intrusion detection system
where multiple switches (i.e. window magnetic reed switches and etc.)
are tied to a bunch of GPIO inputs with userland software that reacts
to the pins changing state.

While here, mention that there is a second, much older version still in
tree, should someone else stumble over both and be confused (e.g., ask
nxr.netbsd.org about jemalloc, forget that it doesn't index anything
under src/external, then read code in the wrong place).
List known supported and obsolete mk.conf(5) variables,
so that searches in this document at least find them.
This partially reverts my revision 1.144 on 2023-06-12
which completely removed the duplication with mk.conf(5).
Remove quote characters from some section headings;
it makes it harder to search for a section by known name
when rendering in markup variations that use smart quotes.
Document that variables set in the environment or the
nbmake-MACHINE wrapper script don't override variable
assignments in mk.conf(5), and that using ?= in mk.conf
allows environment / nbmake-MACHINE variables to override
mk.conf.
Consistently refer to "nbmake-MACHINE wrapper script".
Set MAKECONF to mk.conf in the same directory as build.sh
(i.e., the top of the source tree) if mk.conf is present.
This means unprivileged users can benefit from mk.conf(5)
semantics without write privileges to /etc/mk.conf, and
also simplifies per-source-directory configuration.
Fail early if $MAKECONF is empty, since build.sh will fail
anyway after rebuilding nbmake.
Ensure that the computed MAKECONF isn't empty, and then
always set MAKECONF in the makewrapper (nbmake-$MACHINE).
Improve some formatting consistency in BUILDING.mdoc,
(even if BUILDING is generated without markup).
