Summary: Refactor and streamline PyCFunction_Call

Initial Comment:
Refactor PyCFunction_Call with an eye towards 
clarity and speed while leaving the semantics 
unchanged.  

It is now obvious which combinations of flags are 
allowed; the new structure makes it easier to add new 
flags and flag combinations; and every path runs 
faster (by having fewer jumps, filling variables only 
when and where needed, and by merging a test into 
the switch logic).

* Incorporated the keyword flag test into switch/case.
* Deferred initialization of "size" until when and where 
needed.
* Inverted error tests so that the common case has 
no jumps.
