Support for custom fake function sequences (non-variadic functions)

Browse Source 
This makes it possible to set a sequence of custom fakes for a function
using the macro SET_CUSTOM_FAKE_SEQ. Very useful for functions with out
parameters. Now we don't have to count the number of calls to implement
different behaviours on custom fakes.
