Revise handling of oldstyle/newstyle functions per recent discussions

Browse Source 
in pghackers list.  Support for oldstyle internal functions is gone
(no longer needed, since conversion is complete) and pg_language entry
'internal' now implies newstyle call convention.  pg_language entry
'newC' is gone; both old and newstyle dynamically loaded C functions
are now called language 'C'.  A newstyle function must be identified
by an associated info routine.  See src/backend/utils/fmgr/README.
