binary dump formats.

this code was last gone over, there wasn't really any alternative to
globals because we didn't have the PlannerInfo struct being passed all
through the planner code.  Now that we do, we can restructure things
to avoid non-reentrancy.  I'm fooling with this because otherwise I'd
have had to add another global variable for the planned compact
range table list.

Per example from Jeff Ross.

plan nodes, so that the executor does not need to get these items from
the range table at runtime.  This will avoid needing to include these
fields in the compact range table I'm expecting to make the executor use.

portals using PORTAL_UTIL_SELECT strategy.  This is currently significant only
for FETCH queries, which are supposed to include a count in the tag.  Seems
it's been broken since 7.4, but nobody noticed before Knut Lehre.

equal functions are checked for raw parse trees as well as post-analysis
trees.  This was never very important before, but the upcoming plan cache
control module will need to be able to do copyObject() on raw parse trees.

we can't overflow to the next higher units, and we might print the lower
units for MS.

forces a particular relation nonnullable, then we can say that the OR does.
This is worth a little extra trouble since it may allow reduction of
outer joins to plain joins.

an opclass for a generic type such as ANYARRAY.  The original coding failed
to check that PK and FK columns were of the same array type.  Per discussion
with Tom Dunstan.  Also, make the code a shade more readable by not trying
to economize on variables.

on platforms that need this.  This is done by only writing past the
previously stored message, if it was longer.

JOIN quals, just like WHERE quals, even if they reference every one of the
join's relations.  Now that we can reorder outer and inner joins, it's
possible for such a qual to end up being assigned to an outer join plan node,
and we mustn't have it treated as a join qual rather than a filter qual for
the node.  (If it were, the join could produce null-extended rows that it
shouldn't.)  Per bug report from Pelle Johansson.

require stdint.h and works for "busted" int64.

remove duplicated tests in timestamp, and complete timestamptz with the tests
that were missing to more closely mirror timestamp.

timestamp_tbl table into the timestamp test.  Also, restore a test that
used to exist as a valid test in the timestamptz test.
