Christian Göttsche 2c06566405 LoadMeter: dynamically adjust color and total of bar 
Change the color and total based on the actual 1min load value:

    < 1         : green and total of 1.0
    < cpu-count : yellow and total of cpu-count
    else        : red and total of 2*cpu-count

Christian Göttsche 6e46fd6f1f BarMeter: rework text padding 
In case the text is too long for the bar, try to fit by truncating at a
space character.

Christian Göttsche 157086e750 Split RichString_(append|appendn|write) into wide and ascii 
RichString_writeFrom takes a top spot during performance analysis due to the
calls to mbstowcs() and iswprint().

Most of the time we know in advance that we are only going to print regular
ASCII characters.

Christian Göttsche adf9185209 Fully support non-ascii characters in Meter-Bar 
Currently the code does not handle multi-byte characters, so length-
computations take the raw count of C characters and not the to displayed
size into account.

An example is the degree sign for temperatures.

    value that can later be successfully passed to free().

Hugo Musso Gualandi 9207401f97 Clean up some code duplication in the header files 
PR htop-dev/htop#70 got rid of the infrastructure for generating header
files, but it left behind some code duplication.

Some of cases are things that belong in the header file and don't need
to be repeated in the C file. Other cases are things that belong in the
C file and don't need to be in the header file.

In this commit I tried to fix all of these that I could find. When given
a choice I preferred keeping things out of the header file, unless they
were being used by someone else.

Nathan Scott c5808c56db Consolidate repeated macro definitions into one header 
The MIN, MAX, CLAMP, MINIMUM, and MAXIMUM macros appear
throughout the codebase with many re-definitions.  Make
a single copy of each in a common header file, and use
the BSD variants of MINIMUM/MAXIMUM due to conflicts in
the system <sys/param.h> headers.

Zev Weiss a1a027b9bd Axe automated header generation. 
Reasoning:
 - implementation was unsound -- broke down when I added a fairly
   basic macro definition expanding to a struct initializer in a *.c
   file.

 - made it way too easy (e.g. via otherwise totally innocuous git
   commands) to end up with timestamps such that it always ran
   MakeHeader.py but never used its output, leading to overbuild noise
   when running what should be a null 'make'.

 - but mostly: it's just an awkward way of dealing with C code.

fixed display of blank bars 
The buffer for blank bars was left uninitialized resulting in random
looking characters sometimes even overwriting the end of the bar.
