Support for structs/records in buffers

[robertwb]

Currently only integers, floats and objects are supported in buffers; structs and complex numbers should be supported to.

Complex numbers will be treated as structs containing exactly two floats for now.

Migrated from http://trac.cython.org/ticket/56

I have a lot of code for this now -- however the current strategy for getting around a missing result_code refactor is failing. I either need to move all my temps in IndexNode used for buffer access up to allocation in type analysis phase, or finally do the result_code refactor.

Note that numpy.pxd must still be updated for record structs to work though...
