devd: Warn for deprecated 'kern' system type

One year ago, I deprecated 'kern' in favor of 'kernel' for the system
name for some power events. I'm about to remove it from the kernel, but
realized there's been no warning generated for users. Preserve POLA by
converting on the fly here and issuing a warning for 14.x, and an fatal
error after we branch 15. Make compiling it an error on 16 to remove
the gross hack after we branch.

Merge ^/head r336870 through r337285, and resolve conflicts.

Revert "devd: use C++ style casts"

It seems that nullptr is not yet supported by all compilers used by
FreeBSD. :(

devd: use C++ style casts

devd: use static where possible

We're not, yet, at C++11 capable on all our plaforms.

Use a possibly slower, but C++98 compatibe way to iterate through the
string.

General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
