Explorer09 040613db33 Change variable 'dot' to avoid division by reciprocal.
(Cherry-picked from d56bcd8e0d8d6a177fc2e40db32fc73ea4588684, the
experimental graph coloring branch)

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.

Explorer09 d54ab24d97 New macro GRAPH_HEIGHT for Graph Meter height
(Cherry-picked from e93028d7fa0c5f00b5dc3336fd28abaf905cd572, the
experimental graph coloring branch)

Currently GRAPH_HEIGHT=4 . This prevents hard-coding the height of the graph
meters, and allows user to change it at compile-time.

Hisham Muhammad 09cf369f2b Merge pull request #349 from Explorer09/clamp-macro
Introduce CLAMP macro. Unify all MAX(l,MIN(h,x)) uses.

Explorer09 6dae8108f8 Introduce CLAMP macro. Unify all MIN(MAX(a,b),c) uses.
With the CLAMP macro replacing the combination of MIN and MAX, we will
have at least two advantages:
1. It's more obvious semantically.
2. There are no more mixes of confusing uses like MIN(MAX(a,b),c) and
   MAX(MIN(a,b),c) and MIN(a,MAX(b,c)) appearing everywhere. We unify
   the 'clamping' with a single macro.
Note that the behavior of this CLAMP macro is different from
the combination `MAX(low,MIN(x,high))`.
* This CLAMP macro expands to two comparisons instead of three from
  MAX and MIN combination. In theory, this makes the code slightly
  smaller, in case that (low) or (high) or both are computed at
  runtime, so that compilers cannot optimize them. (The third
  comparison will matter if (low)>(high); see below.)
* CLAMP has a side effect, that if (low)>(high) it will produce weird
  results. Unlike MIN & MAX which will force either (low) or (high) to
  win. No assertion of ((low)<=(high)) is done in this macro, for now.

This CLAMP macro is implemented like described in glib
<http://developer.gnome.org/glib/stable/glib-Standard-Macros.html>
and does not handle weird uses like CLAMP(a++, low++, high--) .

Michael McConville 918cfd54d6 Fall back to sysctl's command name, and a bugfix
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.

Michael McConville 22cfda6332 OpenBSD fixes and updates
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.

Martin "eto" Misuth c67e482c67 fixed bug with PPID of parent not being set on first process list scan pass.
this caused htop to show processes as if freebsd kernel was their parent.
on next pass reparenting code took chance to run, and that caused process to jump around.
this fixed behaviour should be the correct one
