Fix compilation on Python3 while still compiling on recent Python2: - change the handling of files, tweak the generator, get the fd instead of the FILE *, dup it and fdopen based on mode, add a Release function on Python3 and call to flush from the generated python stubs - switch to using Capsules instead of CObjects - fix PyString to PyBytes - fix PyInt to PyLong - tweak the module registration to compile on both versions - drop PyInstance check for passed xmlNodes and instead check attributes presence Daniel
