        src/sys/sys: param.h proc.h

Log Message:
struct proc: Move p_pgrp out of p_startcopy/endcopy region.

It cannot be safely copied with the current memcpy logic that logic
uses happens without holding proc_lock, so we have to copy it
separately anyway.  Leave a comment emphasizing this aspect of the
locking rules so we don't have this bug again.

Looks like p_mqueue_cnt may need similar treatment.

As a result of this kernel ABI change, welcome to 11.99.10!
