Thanks for your work on theora !

I am currently implementing theora for our application.
In our model for generating ogg streams, we may want to stop 
a stream while not providing a new YUV data buffer for encoding.

Current API doesn't allow such thing, since the eos flag is set by the 
packetout function only when the last_p parameter was passed *and* 
there was some data available to output.

Hence, I have written a function that forges this packet, along with NULL 
data, which is allowed by the ogg specifications (and works with other 
encoders, like speex).

Furthermore, since API claims that the 1-1 correspondance with YUV encoded 
buffer and ogg packet might not remain in the futur, I believe such function 
may be usefull in the case when 2, 3 or 4 buffers could be needed to fill a 
new ogg packet..

Patch is attached. I didn't test it yet, but it is mainly packetout's code. I 
believe it is correct, though I don't know if the granulepos and packetno 
should be incremented in this case.
