Add/use typedefs for function pointers

Cleanup: removed unused code for struct return values and pointer arguments.

Implemented external C function linking and change of function signature convention.

The general signature layout for node functions is

void foobar(out1_t *out1, out2_t *out2, ..., in1_t in1, in2_t in2, ...);

All outputs are passed as pointers or references (using references in C code for clarity).
Inputs can be passed by-value or as const pointers/references (for structs and arrays).

In the future we may also support single value return types for convenience.

Correct include guard, remove unnecessary include and struct declarations

Correct comments on header usage.
