Permit sysctl(8) to set an array of numeric values for a single node.

Most sysctl nodes only return a single value, but some nodes return an
array of values (e.g. kern.cp_time). sysctl(8) understand how to display
the values of a node that returns multiple values (it prints out each
numeric value separated by spaces). However, until now sysctl(8) has
only been able to set sysctl nodes to a single value. This change
allows sysctl to accept a new value for a numeric sysctl node that contains
multiple values separated by either spaces or commas. sysctl(8) parses
this list into an array of values and passes the array as the "new" value
to sysctl(2).

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.

Don't request CTLTYPE_OPAQUE if we can't print them.

The intent is to skip expensive opaque sysctls like tcp_pcblist unless
they are explicitly requested. Sysctl nodes like this don't show up in
sysctl -a, but they do generate output that winds up being dropped,
unless the user specifically requested binary/hex output or opaques.

This reduces the runtime of sysctl in many circumstances on a loaded
system. It also reduces the likelihood that simply gathering
diagnostics on a sick machine (stuck lock, etc) via sysctl -a might
push it over the edge into a total lockup.
