	* new split algorithm (as proposed in http://archives.postgresql.org/pgsql-hackers/2006-06/msg00254.php) * possible call pickSplit() for second and below columns * add spl_(l\|r)datum_exists to GIST_SPLITVEC - pickSplit should check its values to use already defined spl_(l\|r)datum for splitting. pickSplit should set spl_(l\|r)datum_exists to 'false' (if they was 'true') to signal to caller about using spl_(l\|r)datum. * support for old pickSplit(): not very optimal but correct split * remove 'bytes' field from GISTENTRY: in any case size of value is defined by it's type. * split GIST_SPLITVEC to two structures: one for using in picksplit and second - for internal use. * some code refactoring * support of subsplit to rtree opclasses TODO: add support of subsplit to contrib modules

	basic regression tests for GiST to the standard regression tests. I took the opportunity to add an rtree-equivalent gist opclass for circles; the contrib version only covered boxes and polygons, but indexing circles is very handy for distance searches.
