Replace planner's representation of relation sets, per pghackers discussion.

Instead of Lists of integers, we now store variable-length bitmap sets.
This should be faster as well as less error-prone.

Extend join-selectivity API (oprjoin interface) so that join type is
...
passed to join selectivity estimators. Make use of this in eqjoinsel
to derive non-bogus selectivity for IN clauses. Further tweaking of
cost estimation for IN.
initdb forced because of pg_proc.h changes.

Revise cost_qual_eval() to compute both startup (one-time) and per-tuple
...

This extension is needed in order to deal realistically with hashed or
materialized sub-selects.

Add a bunch of pseudo-types to replace the behavior formerly associated
...

more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...
