Add support for variable UDP delays.

Browse Source 
This patch adds support for a UDP with variable delays. In the process the
intrinsic support for delays was removed from the UDP functor and replaced
with a call to the .delay functor. Both a normal gate and a UDP now use the
same code to generate the delay.
