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.

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.

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.

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
