Fixes parallel make where each invocation of swig was writing and
deleting the same file resulting in lots of the newly introduced
warning messages:
On exit, could not delete file xxx.py: No such file or directory
Use std::move on this pointer as the default approach to supporting
rvalue ref-qualifiers if a user really wants to wrap.
std::move requires <memory> headers so add swigfragments.swg for all
languages to use common fragments. Just header file fragments for now.
Internally, handle function ref-qualifiers in the function decl type string.
Needed for a whole host of things to work like %feature and %rename.
Add %feature %rename and %ignore testing for ref-qualifiers.
Fixes#1059
Methods with rvalue ref-qualifiers are ignored by default as it is not
possible to have an rvalue temporary from the target language (which is
needed to call the rvalue ref-qualified method).
A warning 405 is shown mentioning the ignored rvalue ref-qualifier method
which can be seen with the -Wextra option.
cpp_refqualifier.i:15: Warning 405: Method with rvalue ref-qualifier ignored h() const &&.
Usually rvalue and lvalue ref-qualifier overloaded methods are written - the
lvalue method will then be wrapped.
