Title: Change udp memory allocation scheme from uv_buf_init to slab allocation.

Takes slab allocation scheme from stream_wrap. Discussed with @ry and @bnoordhuis in IRC. This produced demonstrably better memory usage for a high volume of packets. This has been raised in #2468 amongst other issues. Please see this gist: https://gist.github.com/68890a9ae60e6b0f3bc0 for log output and test files.
