Update usage for ps/w to match previous commit

Display process group in "ps /w" since they got removed from "ps /n".

While here fix the formating of /w /o and /a.

ok guenther@

Display the thread ID (TID) rather than the process group ID (PGRP)
in ddb(4)'s default 'ps' view.

This allow to use 'tr /p' easily now that it requires a TID.

With inputs from guenther@

Rename pfind(9) into tfind(9) to reflect that it deals with threads.

While here document prfind(9.

with and ok guenther@

p_comm is the process's command and isn't per thread, so move it from
struct proc to struct process.

all pools have their ipl set via pool_setipl, so fold it into pool_init.

the ioff argument to pool_init() is unused and has been for many
years, so this replaces it with an ipl argument. because the ipl
will be set on init we no longer need pool_setipl.

most of these changes have been done with coccinelle using the spatch
below. cocci sucks at formatting code though, so i fixed that by hand.

the manpage and subr_pool.c bits i did myself.

Move from struct proc to process the reference-count-holding pointers
to the process's vmspace and filedescs. struct proc continues to
keep copies of the pointers, copying them on fork, clearing them
on exit, and (for vmspace) refreshing on exec.
Also, make uvm_swapout_threads() thread aware, eliminating p_swtime
