std::wstring parameters on SWIG directors were being truncated to a single character due to marshalling inconsistencies.
This patch applies the same MarshalAs(UnmanagedType.LPWStr) attribute to director delegate methods and allows std::wstrings to be successfully received in the C# code via director calls.
Initial contributions for Linux provided in issue #1233, modified to work
on both Windows and Linux. Dual support is possible by detecting
the sizeof wchar_t which is different on each of these systems.
Ruby 3.2 (still in development) started warning about this, see
https://bugs.ruby-lang.org/issues/18007.
Note that the extension docs mention it in
https://ruby-doc.org/core-3.1.1/doc/extension_rdoc.html#label-C+struct+to+Ruby+object:
> The klass argument is the class for the object. The klass should
> derive from `rb_cObject`, and the allocator must be set by calling
> `rb_define_alloc_func` or `rb_undef_alloc_func`.
So in this case we call `rb_undef_alloc_func` to fix the warning.
Verified that this works in robinst/taglib-ruby#115.
Fixes#2257.

pyabc.i for abstract base classes now supports versions of Python
prior to 3.3 by using the collection module for these older versions.
Python-3.3 and later continue to use the collections.abc module.
The -py3 option no longer has any effect on the %pythonabc feature.
Types generated with and without -builtin are not compatible. Mixing
them in a common type list leads to crashes. Avoid this by using
different capsule names: "type_pointer_capsule" without -builtin and
"type_pointer_capsule_builtin" with.

* Mark extern functions with SWIGEXPORT
* Fix bug: builder.sce not generated if with '-scilab -builder' option
Fixes#1853
Fix SWIG_AsWCharPtrAndSize() to actually assign to result variable. It
looks like SWIG/Tcl wide character handling is currently fundamentally
broken except on systems which use wide characters as the system
encoding, but this should fix wrapping functions which take a wide
string as a parameter on Microsoft Windows.
Patch from Omar Medina.

SWIG python objects were being freed after the corresponding SWIG
module information was destroyed in Python 3, causing leaks when as
a result the object destructor could not be invoked. To prevent this
misordering, SWIG python objects now obtain a reference to the
Python capsule wrapping the module information, so that the module
information is correctly destroyed after all SWIG python objects
have been freed (and corresponding destructors invoked).
Fixes#2154Fixes#2208
This was an alternate version without NULL checks on free() and
delete, but we removed those checks globally in
7ec2f89fe2 so now it's just the
same as the active code.
Tests that the `%contract` code (viz., each target language's
implementation of SWIG_contract_assert) compiles in C as expected. Update
the note in the source code since `%contract` is in the official
documentation.
This is necessary for regex-like renames (where you can't use the #define trick
as is done in many of the %keywordwarn directives). It's now unnecessary to print
the "renaming to '`x`'" code explicitly by the kw.swg files.
