joinclauses is determined accurately for each join.  Formerly, the code only
considered joinclauses that used all of the rels from the outer side of the
join; thus for example
	FROM (a CROSS JOIN b) JOIN c ON (c.f1 = a.x AND c.f2 = b.y)
could not exploit a two-column index on c(f1,f2), since neither of the
qual clauses would be in the joininfo list it looked in.  The new code does
this correctly, and also is able to eliminate redundant clauses, thus fixing
the problem noted 24-Oct-02 by Hans-Jürgen Schönig.

Notes/caveats:

        - added regression tests for the new functionality, all
          regression tests pass on my machine

        - added pg_dump support

        - updated PL/PgSQL to support per-statement triggers; didn't
          look at the other procedural languages.

        - there's (even) more code duplication in trigger.c than there
          was previously. Any suggestions on how to refactor the
          ExecXXXTriggers() functions to reuse more code would be
          welcome -- I took a brief look at it, but couldn't see an
          easy way to do it (there are several subtly-different
          versions of the code in question)

        - updated the documentation. I also took the liberty of
          removing a big chunk of duplicated syntax documentation in
          the Programmer's Guide on triggers, and moving that
          information to the CREATE TRIGGER reference page.

        - I also included some spelling fixes and similar small
          cleanups I noticed while making the changes. If you'd like
          me to split those into a separate patch, let me know.

Since builtins.h was already included, I just deleted the extern

uses of the preparedStatement to fail (i.e. the following series of calls
would fail: addBatch() executeBatch() addBatch() executBatch()).  This is
a regression from 7.2 where this worked correctly.  The regression test has
also been modified to explicitly test for this case.
