pgsql: Clean up the API for DestReceiver objects by eliminating the - Mailing list pgsql-committers

Log Message:
-----------
Clean up the API for DestReceiver objects by eliminating the assumption
that a Portal is a useful and sufficient additional argument for
CreateDestReceiver --- it just isn't, in most cases.  Instead formalize
the approach of passing any needed parameters to the receiver separately.

One unexpected benefit of this change is that we can declare typedef Portal
in a less surprising location.

This patch is just code rearrangement and doesn't change any functionality.
I'll tackle the HOLD-cursor-vs-toast problem in a follow-on patch.
