This patch also adds a number of improvements to NativeUdfExpr. Highlights include: * Correctly handling the lowering of AnyVal struct types (required for ABI compatibility) * A rudimentary library cache for reusing handles produced by dlopen * More complicated test cases Change-Id: Iab9acdd7d7c4308e5d7ee3210f21b033fda5a195 Reviewed-on: http://gerrit.ent.cloudera.com:8080/540 Tested-by: jenkins Reviewed-by: Skye Wanderman-Milne <skye@cloudera.com> Tested-by: Skye Wanderman-Milne <skye@cloudera.com>
