clonebundles: advertise clone bundles feature to clients
Server operators that have enabled clone bundles probably want clients
to use it. This patch introduces a feature that will insert a bundle2
"output" part that advertises the existence of the clone bundles
feature to clients that aren't using it.
The server uses the "cbattempted" argument to "getbundle" to determine
whether a client supports clone bundles and to avoid sending the message
to clients that failed the clone bundle for whatever reason.
