Allow counters_read(9) to take an optional scratch buffer.
Using a scratch buffer makes it possible to take a consistent snapshot of
per-CPU counters without having to allocate memory.
Makes ddb(4) show uvmexp command work in OOM situations.

Avoid event counter re-insert in evcount_percpu()
This fixes evcount_list corruption that happened when evcount_percpu()
was called after evcount_init_percpu().

Add support for per-cpu event counters, to be used for clock and IPI
counters where the event being counted occurs across all CPUs in the
system. Counter instances can be made per-cpu by calling evcount_percpu()
after the counter is attached, and this can occur before or after all system
CPUs are attached. Per-cpu counter instances should be incremented using
evcount_inc().

Get rid of evcount's support for arranging counters in a tree
hierarchy. Everything attached to a single root node anyway, so at
best we had a bush.
