Unwrap director classes only when returning a pointer or reference to an object

Browse source 
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.
