bihash table size perf/scale improvements
Directly allocate and carve cache-line-aligned chunks of virtual memory. To a first approximation, bihash wasn't using clib_mem_free(...). We eliminate mheap object header/trailers, which improves space efficiency. We also eliminate the 4gb bihash table size limit. An 8_8 bihash w/ 100 million random entries uses 3.8 Gbytes.
