Subject: thunk: initial commit

Something I slapped together in the interests of mechanizing the creation
of thunks in C.  In this context a thunk is simply a helper function that
serves to normalize the calling convention of functions having potentially
varying arity.

This code has not been used in anything yet, I just put it together because
I anticipate using it soon based on some projects I've been thinking about.

example.c contains a trivial usage example.
