Enhance SWIGTYPE "out" typemaps to use std::move when copying
objects, thereby making use of move semantics when wrapping a function returning
by value if the returned type supports move semantics.
Wrapping functions that return move only types 'by value' now work out the box
without having to provide custom typemaps.
The implementation removed all casts in the "out" typemaps to allow the compiler to
appropriately choose calling a move constructor, where possible, otherwise a copy
constructor. The implementation alsoand required modifying SwigValueWrapper to
change a cast operator from:
SwigValueWrapper::operator T&() const;
to
#if __cplusplus >=201103L
SwigValueWrapper::operator T&&() const;
#else
SwigValueWrapper::operator T&() const;
#endif
This is not backwards compatible for C++11 and later when using the valuewrapper feature
if a cast is explicitly being made in user supplied "out" typemaps. Suggested change
in custom "out" typemaps for C++11 and later code:
1. Try remove the cast altogether to let the compiler use an appropriate implicit cast.
2. Change the cast, for example, from static_cast<X &> to static_cast<X &&>, using the
__cplusplus macro if all versions of C++ need to be supported.

More about the commit:
Added some missing "varout" typemaps for Ocaml which was falling back to
use "out" typemaps as they were missing.
Ruby std::set fix for SwigValueWrapper C++11 changes.
This change does not break backwards compatability
with python, so all works.
The python stuff, however, will still not do all
that ruby can now do.
Updated manual to reflect the change and improve
typemap documentation on the ruby side.

containers that can use one.
Created file rubystdfunctors.swg to allow passing in
Ruby procs as functors to STL functions (swig-user list
suggestion for Python).
Fixed a bug in type_info() always failing for std::set.
Fixed a bug in type_info() always accepting any failed
conversion which could lead to overloaded functions to
fail when input wrong parameters.

Removed object reporting in non-verbose from
newobject demos.
Made wstring treat them as normal strings as
advertised.
