Compiler error messages with and without function pointers in MOCK()

Hello!

I replaced the MOCK() macro and its function pointers with plain functions in my fork for better error messags from the compiler when the wrong arguments are given. See below for compiler error messages with MOCK() and plain functions.

MOCK()
