Fix coredump problem in plpgsql's RETURN NEXT. When a SELECT INTO that's selecting into a RECORD variable returns zero rows, make it assign an all-nulls row to the RECORD; this is consistent with what happens when the SELECT INTO target is not a RECORD. In support of this, tweak the SPI code so that a valid tuple descriptor is returned even when a SPI select returns no rows.

Make tuple receive/print routines TOAST-aware. Formerly, printtup would leak memory when printing a toasted attribute, and printtup_internal didn't work at all...

extern DestReceiver *printtup_create_DR(bool isBinary);
Clean up BeginCommand and related routines. BeginCommand and EndCommand are now both invoked once per received SQL command (raw parsetree) from pg_exec_query_string. BeginCommand is actually just an empty routine at the moment --- all its former operations have been pushed into tuple receiver setup routines in printtup.c. This makes for a clean distinction between BeginCommand/EndCommand (once per command) and the tuple receiver setup/teardown routines (once per ExecutorRun call), whereas the old code was quite ad hoc. Along the way, clean up the calling conventions for ExecutorRun a little bit.

Another SELECT speedup: extract OIDs of column print functions only once per SELECT, not once per tuple. 10% here, 10% there, pretty soon you're talking about real speedups ...
