Autocxx Files

Major changes

• The previous version declared incorrectly that it supported older Rust versions when it didn't. The requirement for newer Rust versions has been removed (thanks to @tanadeau for spotting this in [#1444]).
• This switches internally to a much-less-forked version of bindgen. This should have no user-visible effects but... it will. Everything about the relationship between autocxx and bindgen has changed, so some user-visible changes are bound to be seen. This is work towards [#124].
• There are some changes to the CppRef and related types, which most people don't use, so should not really impact anyone.
