Currently, KNN searches were supported only by GiST. SP-GiST also capable to support them. This commit implements that support. SP-GiST scan stack is replaced with queue, which serves as stack if no ordering is specified. KNN support is provided for three SP-GIST opclasses: quad_point_ops, kd_point_ops and poly_ops (catversion is bumped). Some common parts between GiST and SP-GiST KNNs are extracted into separate functions.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
