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 307c34b028 Hashtable: use dynamic growth and use primes as size
Dynamically increase the hashmap size to not exceed the load factor and
avoid too long chains.

Switch from Separate Chaining to Robin Hood linear probing to improve
cache locality.

Use primes as size to further avoid collisions.

E.g. on a standard kde system the number of entries in the ProcessTable
might be around 650.

Christian Göttsche 7914ec201e Hashtable update
- use consistent type for key by introducing a new typedef
- use unsigned types for sizes
- name parameters in foreach function typedef

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
