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.

Nathan Scott f704baeb82 Drop unused global ProcessList memory fields 
The global ProcessList structure contains a couple of unused
fields.  'sharedMem' has never been used by any Meter, since
its not been anything other than zero in Linux /proc/meminfo
for many, many years.  The freeMem field is only used in the
usedMem calculation, so it can reside on the stack like some
other memory variables used within-calculations-only and not
exposed to the user via a Meter.

Nathan Scott c75c5ef9c6 Minor cleanups to platform-specific init and done 
Move platform-specific code out of the htop.c main function
and into the platform sub-directories - primarily this is
the Linux procfs path check and sensors setup/teardown; not
needed on any other platforms.  No functional changes here.

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.

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.
