Remove support for v0 control protocol from 0.2.0.x trunk; send back error when we receive a v0 control message.  (Leave "if(v1){...}"blocks indented for now so this patch is easier to read.)  ((Finally, the linecount goes _down_ a little.))

30e4f4f6ce when we're doing a write split over the end of a circular
buffer, make sure our tls_get_forced_write_size doesn't
make it write whatever's after the buffer.

this hasn't triggered yet, but it would be rare, so let's
leave it in.

cell if it's running 0.1.2.2-alpha or later. We still need to make
one-hop circs when appropriate, while making other conns avoid them.
