[Telepathy] "Denying a contact" Bug in Empathy

Hi Uday,

Sorry for the very belated reply, and for the lazy top-posting. This 
mail's been in my TODO queue for too long. :)

Your analysis of the problem is correct! The right fix here would be to 
add API to libpurple so that you can decline a subscription request with 
a message, rather than the Yahoo! prpl having to pop up a dialog to ask 
for a message. This API would also be useful on other protocols, like 
MSN, and it would allow Pidgin and other “normal” libpurple UIs to 
present much better UI.

No-one's working on this at the moment. I'd be happy to give pointers, 
and help shepherd the resulting patches into libpurple. :)

(I did start a Haze branch that made it always respond to 
purple_request_*() operations, picking a callback arbitrarily, but I 
wasn't really happy with it...)
