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

Christian Göttsche 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.
