If android_setsocknetwork() is available, and it fails, then bind() should *not* be called, and an error should be returned. If it succeeds, then bind should be called, but with an "any" address. This is to prevent cases where sockets are sent with a source address that doesn't match the network interface they're sent on. See bug below. This CL also changes "NetworkBinderResults" to an enum class, and renames it to "NetworkBinderResult".
