The $isvoid special variable expands to 1 if the
wrapped function has a void return, otherwise expands to 0.
In the implementation, use a consistent variable name, returntype,
for a node's "type" attribute.
Issue #2907
A different approach is taken for supporting casting smart pointers up the
inheritance hierarchy. We no longer try to replace the underlying pointer type,
provided in the 'feature:smartptr', with the base class type. Such as morphing
'std::shared_ptr<(Derived)>' into 'std::shared_ptr<(Base)>'. Instead, we simply
use 'feature:smartptr' from the base class. This is more reliable than trying to
pattern match the pointer type in the feature. The base class must of course
also have the 'feature:smartptr' set, and this is still checked for as before.
The feature is now parsed in one place and stored in the parse tree in the
new 'smart' attribute for handling by the target languages.
Fix also improves the handling of the type parsed in 'feature:smartptr' in that
the type is now normalized and resolved in the scope of the class it is attached
to.

Don't generate calls to
SWIGPY_BINARYFUNC_CLOSURE(_wrap___lshift__)
for the 'global' function wrappers for the friend functions.
Only occurred when a friend class is within a namespace due to the
renames in pyopers.swg, such as:
%rename(__lshift__) *::operator<<;
The rename was intended for member functions but was also being attached
to friends that are within a namespace.
Since this was first added, the -py3 option has been dropped
and the Stable ABI is known as exactly that, not the Python3 Stable ABI.
Document the new option and turn on c++20 testing for it to cover
std::filesystem and std::string_view testing which are affected

These features were all deprecated in 1.3.26 (October 9, 2005)
or before (many long before), so all more than 17 years and 3 new major
versions ago which seems more than enough time for users to have stopped
using them, especially as most emit a deprecation warning if used.
Further corrections to pass SwigType * to methods expecting types
instead of passing readable type strings.
Swig_string_mangle() takes a generic String *, but it was calling
functions that require SwigType *. Swig_string_mangle_type() is
now provided for SwigType *.
The previous commit is a pre-requisite in order to prevent duplicate
symbols from being generated in the C++ wrappers.
Add Swig_obligatory_macros which must be called by each
target language to define SWIG_VERSION correctly
in the generated code, as well as the language specific
macro SWIGXXX where XXX is the target language name.
Drop the #ifdef SWIGXXX that was previously generated -
I can't see the point of this and if users are defining
this macro somehow, then users will need to change this
Closes#1050
Resolve the return type to correctly determine if the type is a pointer or
reference to a director class.
SwigType_refptr_count_return() recently added as a simpler fix is no
longer needed.
The conventional approach of using the "type" rather than "decl" to
analyse the return type is used instead too.
Issue #1823
If a "docstring" feature is present it will still override a Doxygen comment.
If the "autodoc" feature is also present, the combined "autodoc" and "docstring"
will override the Doxygen comment. If no "docstring" is present then the
"autodoc" feature will not be generated when there is a Doxygen comment.
This way the "autodoc" feature can be specified and used to provide documentation
for 'missing' Doxygen comments.

The version checking was historically done to deal with
different versions and importing the low-level Python
module. Then it was used to try and help when using -py3.
A minimum version check implies that the wrappers work
with any version >= 2.7, which is not really correct.
The correct thing to do is to check that the exact
version used matches the one that the C layer was compiled
against, which can only be left for the user to do, perhaps
using %pythonbegin.
Issue #1779
A metaclass is added using a decorator @_swig_add_metaclass which
is designed to provide a metaclass that works for both Python 2 and Python 3.
The option to use the Python 3 only syntax: metaclass=_SwigNonDynamicMeta
via the -py3 command line option has been removed as part of a
simplification to remove the -py3 option.
Issue #1779
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.
Correct logic for suppressing static methods.
Previous logic was missing director disown methods.
Add changes file entry for -flatstaticmethod.
Closes#2137
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.

Exit() is a wrapper for exit() by default, but SetExitHandler() allows
specifying a function to call instead.
This means that failures within DOH (e.g. Malloc() failing due to lack
of memory) will now perform cleanup such as removing output files.
This commit also cleans up exit statuses so SWIG should now reliably
exit with status 0 if the run was successful and status 1 if there was
an error (or a warning and -Werror was in effect).
Previously in some situations SWIG would try to exit with the status set
to the number of errors encountered, but that's problematic - for
example if there were 256 errors this would result in exit status 0 on
most platforms. Also some error statuses have special meanings e.g.
those defined by <sysexits.h>.
Also SWIG/Javascript tried to exit with status -1 in a few places (which
typically results in exit status 255).
