as suggested by @Explorer09. It's not really faster.

(Stupid me for forgetting to delete the line when changing code in commit 5c18866e )

Thank you @Explorer09 for the report!

Fix typo: prority => priority

add some security checks when running SUID root

use AC_HELP_STRING for proc dir

Rename variable for consistency

Suggested by Hisham.

align help output

Plug mem leak, improve CPU enumeration logic

These are never necessary when using the standard library.

I think this leak may still exist in the FreeBSD port.

Should fix #321.

OpenBSD fixes and updates

Fix spelling of "maintainer"

This is what OpenBSD's top(1) does when the libkvm call fails, and it's
a good idea.

This commit also fixes process name construction. The space was being
written one character too far.

Even when they're constant, as is the case for zombie processes.

So that we can see errno. Pointed out by Michael Reed.

I forgot how awful the process name logic was. It was an initial hack to
get it running, and I forgot to clean it up.

I also had to change a few includes and error function uses.

The variable 'dot' in GraphMeterMode_draw now means "maximum number of
dots per value (column) in graph". The old meaning was "amount of value
that is to be represented by a dot" and was always a fraction. Due to
a limitation in floating point computing, if GRAPH_HEIGHT were not a
power of 2, then rounding errors will occur on numbers like (1.0/3).
(Currently GRAPH_HEIGHT is 4 and so no precision loss.) 'dot' was used
as a divisor, and it's "division by a reciprocal". We change that to
simple multiplication.

This allows the graph be rendered with a differ color scheme when user
changes the color scheme.
