Phase 1 of read-only-plans project: cause executor state nodes to point to plan nodes, not vice-versa. All executor state nodes now inherit from struct PlanState. Copying of plan trees has been simplified by not storing a list of SubPlans in Plan nodes (eliminating duplicate links). The executor still needs such a list, but it can build it during ExecutorStart since it has to scan the plan tree anyway. No initdb forced since no stored-on-disk structures changed, but you will need a full recompile because of node-numbering changes.

Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments.

New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass.
