Add forest (-f) mode

In -f mode group & display parent/child process relationships using ASCII art.

Borrows heavily from Brian Somers' work on FreeBSD ps(1).

With input from deraadt@ and tb@

OK benno@ claudio@

Delete 'emul' keyword: it's been just returned 'native' for a long time

/bin/ps: Implement reporting of supplemental groups

with help from sthen@ and tim@. OK tim@

add "ps -o pledge" option, which prints a comma-seperated list of pledges
active on each process. So go forth and "ps agux -o pledge" to find pledges
which can be improved.

(I hesitated adding this before because I am afraid of people
enforcing extra-strict pledge in programs without testing all the use
cases -- thereby breaking software).

etime isn't just an alias for start. the output format is different.
diff from Carlin Bingham. ok millert.

UTF-8 support:
In a UTF-8 locale, columnate correctly and replace valid, but non-
printable characters with the Unicode replacement character U+FFFD.
No change in the C/POSIX locale, and no change for invalid bytes.
Grand total, the code becomes shorter by almost 30 lines.
Feedback from czarkoff@, OK millert@.

rename a few variables/functions to avoid shadowing

After removing the p_swtime from the kernel, ps always printed 0.0
as %cpu time. Remove the calculation in ps that includes the process
lifetime. Just print the p_pctcpu value, that was done before when
ps was called with -C. Keep -C as a no-op for existing scripts.
OK millert@

Suppress the header line if all the field headers have been set to empty.

Make ps understand -o cwd using the new KERN_PROC_CWD sysctl. Some help
and suggestions from guenther.

Switch back from KERN_PROC2/kinfo_proc2 to KERN_PROC/kinfo_proc now
that we've got name we want for the API we want

"ZAP!" deraadt@

Format nicelevel relative NZERO as other tools do.
Surely, says millert.

avoid negative memory sizes, ok deraadt@

rename internal uname() to euname() to avoid libc conflict

Convert to kinfo_proc2. The sort order for -u and -m will be different
due to a bug fix in the sort routine.

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

add dsiz and ssiz to accompany tsiz; millert@ ok

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

Get MAXSLP from kvm/sysctl. It's patchable in the kernel now.

add ps "emul" option

XPG4 compatibility for format options:
two new options: group and rgroup.
three new aliases: etime for start, comm for ucomm, and args for command.
