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

0806a7958b Assert Vector_get returns an object 
It is generally assumed Vector_get returns a non-NULL object.
Use a generic assert in Vector_get instead of in callers.
