POC: Port native C++ geospatial functions to WKB mode
Implement native C++ ST_ geospatial functions for WKB_EXPERIMENTAL mode
so they no longer fall back to the Java (ESRI) implementations. Builds on
the WKB serialization foundation (common.h / wkb-format.h /
wkb-serialization.*) added in the previous commit. Kept as a single
commit; it can be split further later if desired.
Adds:
- geometry-wrapper-wkb.{h,cc}: GeometryWrapperWkb -- deserializes WKB into
boost::geometry types and back, and hosts the geometry property methods
(Area/Length/Distance/Centroid/...).
- relation-wrapper-wkb.{h,cc} (+ relation-wrapper-wkb-test.cc): native
relation predicates (Contains/Crosses/Disjoint/Equals/Intersects/
Overlaps/Touches/Within), with C++ unit coverage.
- geospatial-functions-wkb-ir.cc: the _WKB IR entry points -- accessors,
constructors, predicates, transformations, binning and properties.
- wkt.h: WKT read helpers; bin-utils.h: ST_Bin binning helpers.
- HiveEsriGeospatialBuiltins.addWkbNatives(): registers the natives in
WKB_EXPERIMENTAL mode; functions not registered fall back to Java.
- impala-ir.cc include + scalar-expr-evaluator force-refs so the IR is
compiled into the codegen module and not stripped.
New geo files use the bg:: alias (= boost::geometry) to match common.h.
Tests:
- relation-wrapper-wkb-test.cc: C++ coverage of the relation predicates.
- test_wkb_experimental_relations_table + geospatial-relations-table.test:
native relations over functional.geom_relations_wkt.
- The existing WKB geospatial tests now exercise the native path.
- ST_NumPoints of an empty point (0 in ESRI; 1 in the WKB native, since
boost has no empty-point concept) moved to geospatial-esri-specific-
overloads.test as an ESRI-only case, pending unified empty-point handling.
