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.
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.
Remove redundant NULL checks before free()/delete
The ISO C and C++ standards guarantee that it's safe to call these
on a NULL pointer, so it's not necessary for the calling code to
also check.

Use sizeof variable name rather than variable type.
Workaround Visual C++ unable to parse some complex C++11 types, such as
sizeof(short (Funcs::*)(bool) const &&)
This is actually a fix to some functionality that I submitted many years ago. :) At the time I set the string conversion to output the userdata address, but since that points to an internal SWIG structure, it's way more useful to the user to point to the actual memory being wrapped in that userdata.
Tests for std::vector of pointers added which check
std::vector<T*>::const_reference and std::vector<T*>::reference
usage which gave compilation errors in Python and Perl which had
specialized these vectors incorrectly.
When a C++ class defined a __getitem function the base classes where
never used for resolving methods. This fix first scans the '.get' and
'.fn' tables of all base classes and only if there is no result does the
same for __getitem functions.
Since Lua 5.3 the "%c" format character in lua_pushfstring will produce
the string "<\XXX>" (XXX being a decimal code sequence) when
given unprintable characters.
Use lua_pushlstring instead to reproduce the old behavior.
* Renamed SWIG_Lua_equal to SWIG_Lua_class_equal
* If class has no __eq implemented, then default __eq is provided.
Default __eq compares actual pointers stored inside Lua userdata
