The new protocol from the kernel encodes things as a string table,
extract it into fields. strdup the strings, and free them when we're
done.

Sanity check the return from the kernel.2018-05-31T02:57:51ZWarner Loshimp@FreeBSD.org2018-05-31T02:57:51Zurn:sha1:92376fa76c0b342f61d8b8505119bdf56d5af781
We should be getting back as many bytes as we asked for, and we
don't handle shortages at all, so just reject anything that's
not right.

Bump number that's an insane number of devices from 1,000 to 10,000. I2017-12-21T04:21:59ZWarner Loshimp@FreeBSD.org2017-12-21T04:21:59Zurn:sha1:41ec95c47fd3bac8549d0b5d424eaa2b6420e47d
have access to machines that are pushing 400 devices. When 1,000 was
selected, it was rare to get even 40 or 50 devices. Bump the limit by
10x to keep up with the times.

lib: further adoption of SPDX licensing ID tags.2017-11-26T02:00:33ZPedro F. Giffunipfg@FreeBSD.org2017-11-26T02:00:33Zurn:sha1:5e53a4f90f82c4345f277dd87cc9292f26e04a29
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified 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.

cached state. Otherwise, a subsequent call to devinfo_init() would succeed
without reading the device tree from the kernel thinking that the cached
state was up to date since the generation count was the same. However,
since the cached state was actually free'd, attempts to examine the tree
after the second devinfo_init() would fail.
