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.
