Don't use array size in function arguments

The declaration of argv_to_string() mismatched its definition. The
definition had the array size, the declaration had not. Remove array sizes
from all functions declared in argv.h.

Array sizes in function arguments don't ensure the code correctness but can
give a wrong impression that the compiler would check the array size.
