chg: change server's process title
This patch uses the newly introduced "setprocname" interface to update the
process title server-side, to make it easier to tell what a worker is actually
doing.
The new title is "chg[worker/$PID]", where PID is the process ID of the
connected client. It can be directly observed using "ps -AF" under Linux, or
"ps -A" under FreeBSD.
