Log:
This commit adds a new metrics export mechanism to smbd. Per-share and
per-client metrics are exported from a shared mmap. The exported records
contain counts of interesting classes of system calls, as well as I/O
sorted into a small number of size-based buckets. The mmap is growable
and will become larger as more clients connect.

The existing shared memory metrics export mechanism is unmodified for
compatibility reasons.

Also included is an enhanced PCP metrics agent that published metrics
from both the new extended metrics code and the original shared memory
statistics. This shows how a metrics consumer can be written to handle
the backing store being remapped as it grows. smbstatus -P shows a simple
one-show metric consumer.
