Christian Göttsche 15eab2012d Add process column for normalized CPU usage 
Shows the process CPU usage divided by the number of CPU cores

Christian Göttsche 397b5c4bd0 Introduce spaceship comparison for Processes 
If currently two unsigned values are compared via `a - b`, in the case b
is actually bigger than a, the result will not be an negative number (as
-1 is expected) but a huge positive number as the subtraction is an
unsigned subtraction.

Avoid over-/underflow affected operations; use comparisons.
Modern compilers will generate sane code, like:
    xor     eax, eax
    cmp     rdi, rsi
    seta    al
    sbb     eax, 0
    ret

Christian Göttsche 96e2a4259e Continue to update generic data in paused mode 
Generic data, as CPU and memory usage, are used by Meters.
In paused mode they would stop receiving updates and especially Graph
Meters would stop showing continuous data.

Closes: #253

Add a date and datetime meter (#159) 
Add a date meter and sort header and source files in Makefile

Change the lists of header and source files sorted alphabetical and one
file per line. This way diffs become better readable and merges easier.

multi 9ee72568dc CPUMeter: add octuple-column CPU meters. 
This is a straightforward extension of the existing multi-column CPU meter
code, which now allows for up CPU meters to be displayed in up to 16 columns.

This also adds the meter declarations to all the platform-specific code.

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.

Nathan Scott 8ec5d4a3a0 Further, minor cleanups to headers post-MakeHeaders 
Remove leftover empty ifdef/endif pairs, whitespace.
The generated htop.h file was also unused - removed.

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.
