Nathan Scott b2a8b2426e Tweak style guide wording around single code statements 
There was wording about brace-enclosing single code statements
being 'strongly encouraged' - this isn't consistently used and
IMO it introduces unnecessary noise in otherwise neat, concise
code.

I've reworded (dropped) this section and also fixed a handful
of minor typos while reading this doc a little more carefully.

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 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
