packages: Move powerd to its own package

Nearly everyone wants powerd to manage CPU frequency scaling on real
hardware, even if -utilities isn't installed. Conversely, very small
jails might want -utilities but don't need powerd.

Move it to its own package and add it to the minimal set.

Remove residual blank line at start of Makefile

This is a residual of the $FreeBSD$ removal.

Since APM is a legacy technology, that won't be adapted to other
platforms, move the test for i386 from the Makefile to powerd.c. The
powerpc specific checks are already done this way...

Merge from head at r201628.

# This hasn't been tested, and there are at least three bad commits
# that need to be backed out before the branch will be stable again.

The last big commit: let usr.sbin/ use WARNS=6 by default.

Don't use threads when there's no real reason to.

Use a pipe for reading devd events as another method of getting the AC line
status. Add a thread that waits for events on the named pipe instead of
polling the line status via apm or the ACPI sysctl

Use a pipe for reading devd events as another method of getting the AC line
status. Add a thread that waits for events on the named pipe instead of
polling the line status via apm or the ACPI sysctl. Additionally, use
robust error handling in case devd goes away or we temporarily can't set
a frequency (i.e., passive cooling has preempted our setting).

Later, this should be improved so that if adaptive control is not being used,
we will block while waiting for AC line events, saving a little CPU.
