measurement of load caused by time-related events still using hardclock.
For example, without this change dummynet, scheduling events each hardclock
tick, was always miscounted as load of 1.
There is still aliasing with events delayed by the new precision mechanism,
but it probably can't be avoided without moving this sampling from using
callout to some lower-level code or handling it in some other special way.

generates a configuration suitable for running unbound as a caching
forwarding resolver, and configures resolvconf(8) to update unbound's
list of forwarders in addition to /etc/resolv.conf. The initial list
is taken from the existing resolv.conf, which is rewritten to point to
localhost. Alternatively, a list of forwarders can be provided on the
command line.
To assist this script, add an rc.subr command called "enabled" which
does nothing except return 0 if the service is enabled and 1 if it is
not, without going through the usual checks. We should consider doing
the same for "status", which is currently pointless.
Add an rc script for unbound, called local_unbound. If there is no
configuration file, the rc script runs local-unbound-setup to generate
one.
Note that these scripts place the unbound configuration files in
/var/unbound rather than /etc/unbound. This is necessary so that
unbound can reload its configuration while chrooted. We should
probably provide symlinks in /etc.

ISelDAG: spot chain cycles involving MachineNodes
Previously, the DAGISel function WalkChainUsers was spotting that it
had entered already-selected territory by whether a node was a
MachineNode (amongst other things). Since it's fairly common practice
to insert MachineNodes during ISelLowering, this was not the correct
check.
Looking around, it seems that other nodes get their NodeId set to -1
upon selection, so this makes sure the same thing happens to all
MachineNodes and uses that characteristic to determine whether we
should stop looking for a loop during selection.
This should fix PR15840.
Specifically, this fixes the long-standing assertion failure when
compiling the multimedia/gstreamer port on i386. Thanks to Tijl
Coosemans for his help in getting upstream to fix it.
