[Python.NET] Python 2.5 compatibility and interop.cs

[Brian Lloyd]

I'm pretty sure there were some changes to type structures in 2.5, so
probably the only sane thing to do would be to do a 2.5-specific branch :(

The interop stuff is some fairly deep voodoo - it essentially generates a
bunch of thunks and wrappers matching the in-memory layouts of various
python type objects and things. What would need to be done is an assessment
of what changed in 2.5, then go into interop and change / add offsets etc.
accordingly. I can say with some experience that it won't be fun ;)

My available time (and the fact that IronPython gets 99% of the oxygen
these days) means that I probably won't be able to get to this any time
soon, but I'd be more than happy to help anyone who wants to take this on
in any way I can.
