Clear conversation window from a protocol prpl

I composed a copy of this and then TB ate it, so apologies if it
actually got sent twice.

That function seems to clear a libpurple copy of the message history
(which I didn't know existed until today).  Sadrul indicates that it's
not used now, but is planned to be used more extensively in 3.0.0+.

I think it would probably be reasonable for that function (as a 2.8.0
change) to also emit a signal to the UI (which Pidgin could attach to
the 'clear scrollback' functionality).  Do any developers/others have
any use cases for clearing either the scrollback or in-memory copy, but
not both?
