During the review of the patch about improved PL/Python data type support, I 
figured this could be somewhat simplified if PL/Python used the errcontext() 
mechanisms instead of passing the function name around everywhere in order to 
use it in error messages.

I have produced the attached patch.  The errcontext stuff is a bit obscure to 
me though, so perhaps someone could look it over.
