This involves properly counting the number of references and pointers in the return type of a function and only generate unwrapping code if this number is 1. For template instances some post-processing code is added to fix the 'decl' and 'type' attributes of functions if changed in an unfavorable way during template expansion. This commit fixes swig#1811.
