Bugfix: Compilation/Portability problems exposed when building against musl-libc.

Some headers are missing.

Change the length types: f_console_parameter_size and f_array_length_t.
I have seen problems where the max allowed size is reached in f_array_length_t.
Compiling against musl-libc further exposes this problem and so I have reduced the practice to using a set length of 2^63 (aka: signed long).
