Unfortunately the changes of 26bf86322 (Use SWIG-specific for
non-overloaded synthesized functions too, 2021-11-09) did break some
existing code bases using SWIG as they hardcoded the old wrapper
function names.
So turn this off by default and add a global variable allowing to enable
this, which can be done for a specific language only. This is ugly but,
unfortunately, there is no way to use the Language object from the C
function Swig_MethodToFunction(), so the only alternative would be to
add another parameter to it, but it already has 6 of them, so it
wouldn't really be that much better.
See #2366, #2368, #2370.
The C++ wrappers create a temporary variable for a parameter to be passed to a
function. This is initially default constructed and then copy assigned from the
instance being passed in from the target language. This is unchanged, however,
when the temporary variable is passed to wrapped function, it is now done using
std::move. If the type is move constructible, the move constructor will be used
instead of the copy constructor.
Note that the implementation calls std::move for all user-defined types
(non-primitive types passed by value), this excludes anything passed by pointer,
reference and arrays. It does also include any type that has not been
defined/parsed by SWIG, that is, unknown types. std::move is called via the
SWIG_STD_MOVE macro which only calls std::move for C++11 and later code.
This avoids conflicts between such functions, which are generated when
using %extend to add static methods to an existing class, and the actual
wrapper functions generated by the backend.
This shouldn't result in any user-visible changes.
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.
Test case is slightly modified from the test case in issue #250
Use of constant objects does not seem to work in Python - the type is
SwigPyObject instead of constant_directive.Type1.
Fixes problem with method overloading when some methods are added by %extend
and others are real methods and using template default parameters with smart pointers.
This is noticeable as a regression since 2.0.12 when using the default smart pointer
handling for some languages when the smart pointer wraps std::map and other STL containers.
Fixes SF Bug 1363
Error checking for this combination implemented as well as correcting
Octave
Also refactor, replacing CPlusPlusOut variable with cparse_cplusplusout
for an implementation which more closely resembles cparse_cplusplus which
is also required in both .c and .cxx files.
Suitable casts are required so that assignment of instances of nested classes
work as the nested class is duplicated in the global namespace, eg:
struct Outer {
struct Nested {
int bar;
} bar_instance;
};
Outer.bar_instance can now be assigned to.

This is a preparation for moving to new DOH, since for strong typed objects we need the const_String_or_char_ptr class to implicit convert to and from String * or const char *.
