Add unmarshal callback directive

msgp has the ability to call functions specified as directives for a certain type.
the function would be called at the end of unmarshaling.

error-free MarshalMsg

The only possible case that could have generated an error during encoding
was from encoding an interface, which we never used (and thus we were
already strongly assuming no error would be returned). This change
removes the ability to encode interfaces, which means MarshalMsg()
will never return an error.

Add summary, unit test build tag and avoid interface warnings

1. On the header of the generate files, there is a summary of which objects and function are implemented.
2. On each of the generated test file, a build tag was added. This buildtag could be used to exclude the build of the unit tests.
   ( needed for testing of encoding using non-test code )
3. Interfaces are now correctly detected, and would not generate warning during msgp execution.
