datapath: Convert upcalls and ODP_EXECUTE to use AF_NETLINK socket layer.

This commit calls genl_lock() and thus doesn't support Linux before
2.6.35, which wasn't exported before that version.  That problem will
be fixed once the whole userspace interface transitions to Generic
Netlink a few commits from now.
