bundle2: introduce `replycaps` part for on-demand reply
The bundle2 processing does not create a bundle2 reply by default anymore. It
is only done if the client requests it with a `replycaps` part. This part is
called `replycaps` as it will eventually contain data about which bundle2
capabilities are supported by the client.
We have to add a flag to the test command to control whether a reply is
generated or not.

globalvars = {}

snippet = l[4:]
while lines and lines[0].startswith('... '):
l = lines.pop(0)
snippet += "\n" + l[4:]
c = compile(snippet, '<heredoc>', 'single')
try:
exec c in globalvars, localvars
