Finds nodes in a pxd file that should generate code, and

returns them in a StatListNode.

The result is a tuple (StatListNode, ModuleScope), i.e.

everything that is needed from the pxd after it is processed.

A purer approach would be to separately compile the pxd code,

|
|
but the result would have to be slightly more sophisticated
|

|
than pure strings (functions + wanted interned strings +
|

|
wanted utility code + wanted cached objects) so for now this
|
||
|

approach is taken.
