[Pyrex] Pointers

[Javier Correa]

Defining:
   ctypedef struct _CMesaDevice
   ctypedef _CMesaDevice * SRCAM

got rid of some problems, sorry I wasn't getting how to use the incomplet
types.

I still have a problem with the void* return type:
 Cannot convert 'void *' to Python object
when I try to do:
...
      cdef void * images
...
      image = SR_GetImage(self.cam, 0)
