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

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.

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.
