list compatibility API by default. While doing this, I decided to keep the llast() macro around and introduce llast_int() and llast_oid() variants.

* copyfuncs.c
* Copy functions for Postgres tree nodes.
*
* NOTE: we currently support copying all node types found in parse and
* plan trees. We do not support copying executor state trees; there
* is no need for that, and no point in maintaining all the code that
* would be needed. We also do not support copying Path trees, mainly
* because the circular linkages between RelOptInfo and Path nodes can't
* be handled easily in a simple depth-first traversal.
