check for all elements of wrapped function in gotcha

[dsikich]

Make sure there is a warning if any of the required elements for a wrapped function are missing. For instance, if a prototype for a wrapped function is declared, but it is not added to the gotcha struct that function will not be intercepted.

Things to check:

• Each wrapped function prototype also has a pointer to the original function defined and visible to the gotcha struct
• The number of wrapped functions should match the number of functions defined in the gotcha struct
