543b9d5960 Expose the ACPI power button, sleep button and LID state as evdev's.
This allows libinput to disable touchpads when the lid is closed and
various desktop environments can show power-off dialogs when the power
button is pressed. While the latter is doable with devd a
cross-platform solution is nicer.

8d03b99b9d fd: move vnodes out of filedesc into a dedicated structure
The new structure is copy-on-write. With the assumption that path lookups are
significantly more frequent than chdirs and chrooting this is a win.

This provides stable root and jail root vnodes without the need to reference
them on lookup, which in turn means less work on globally shared structures.
Note this also happens to fix a bug where jail vnode was never referenced,
meaning subsequent access on lookup could run into use-after-free.

f8b9b299a2 linuxulator: Map scheduler priorities to Linux priorities.
On Linux the valid range of priorities for the SCHED_FIFO and SCHED_RR
scheduling policies is [1,99].  For SCHED_OTHER the single valid priority is
0.  On FreeBSD it is [0,31] for all policies.  Programs are supposed to
query the valid range using sched_get_priority_(min|max), but of course some
programs assume the Linux values are valid.

This commit adds a tunable compat.linux.map_sched_prio.  When enabled
sched_get_priority_(min|max) return the Linux values and sched_setscheduler
and sched_(get|set)param translate between FreeBSD and Linux values.

Because there are more Linux levels than FreeBSD levels, multiple Linux
levels map to a single FreeBSD level, which means pre-emption might not
happen as it does on Linux, so the tunable allows to disable this behaviour.
It is enabled by default because I think it is unlikely that anyone runs
real-time software under Linux emulation on FreeBSD that critically relies
on correct pre-emption.

This fixes FMOD, a commercial sound library used by several games.

d91382866f Add -N option to powerd(8) to ignore "nice" time.
With powerd_flags="-N", this makes powerd(8) exclude "nice" time when
computing the CPU utilization.  This makes it possible to prevent
CPU-intensive "background" processes from spinning up the CPU.

Note that only *userland* CPU usage belonging to "nice" processes is
excluded; we do not track whether time spent in the kernel is on behalf
of nice or non-nice processes, so kernel-intensive nice processes can
still result in the CPU being sped up.

134b378392 retire in-tree GPL dtc devicetree compiler
Now that we no longer have GCC 4.2.1 in the tree and can assume FreeBSD
is being built with a C++11 compiler available, we can use BSDL dtc
unconditionally and retire the GPL dtc.

GPL dtc now has FreeBSD CI support via Cirrus-CI to help ensure it
continues to build/work on FreeBSD and is available in the ports tree
if needed.

The copy of (copyfree licensed) libfdt that we actually use is in
sys/contrib/libfdt so the extra copy under contrib/dtc/libfdt can be
removed along with the rest of the GPL dtc.
