a9545eede4 Add idle priority scheduling privilege group to MAC/priority
Add an idletime user group that allows non-root users to run processes
with idle scheduling priority. Privileges are granted by a MAC policy in
the mac_priority module. For this purpose, the kernel privilege
PRIV_SCHED_IDPRIO was added to sys/priv.h (kernel module ABI change).

Deprecate the system wide sysctl(8) knob
security.bsd.unprivileged_idprio which lets any user run idle priority
processes, regardless of context. While the knob is still working, it is
marked as deprecated in the description and in the man pages.

bf2fa8d9d1 MAC/priority module for realtime privilege group
This is a MAC policy module that grants scheduling privileges based on
group membership.  Users or processes in the group realtime (gid 47) are
allowed to run threads and processes with realtime scheduling priority.
For timing-sensitive, low-latency software like audio/jack, running with
realtime priority helps to avoid stutter and gaps.

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.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

981dfb0965 - Fail when the utility is not invoked as rtprio nor idprio.
- use warnx() to tell the user whether a process is running in normal,
   idle or realtime priority. with the old code it would have been possible
   for another process to send data to stdout between
	printf("%s: ", p);
   and
	printf("* priority\n");
   and thus break the formatting.
 - 'rtprio 10 -0' triggeres non-intuitive behavior.  It would first set the
   priority of itself to 10 *and* would then try to execute '-0'. Of course,
   setting the priority of [id|rt]prio itself doesn't make a lot of sense,
   but it is intuitive compared to the previous behavior.
 - 'rtprio -t --1' will actually pass over the '-1' to rtprio().  Now
   invoking rtprio like this will catch the wrong usage before passing
   over the invalid argument to rtprio().
 - Garrett Cooper suggested to add further diagnostics where the failure
   occures, if execvp fails.
