sole: properly support multiple sessions
We update the sole protocol to more cleanly support multiple sessions.

Primarily, the "sole id" is updated to be a [@p @ta] instead of a @ta,
and it is now generated based off the connected dill session, rather
than statically.

This change ripples out to applications that support the sole protocol:
the subscription path becomes /sole/[ship]/[session] (as opposed to
/sole/[per-ship-constant]), and %sole-action pokes include the new id as
well.
For shoe agents, this means (at the very least) updating the function
signatures of the shoe arms.

/lib/sole has been updated to include helper functions for parsing a
sole-id from a subscription path, and turning a sole-id into its
corresponding path. It also has a function to aid in migrating old
sole-ids.

Existing sole agents are made to kick any known open sessions, forcing a
resubscribe by drum, so that they may use exclusively the new format
going forward. Third-party agents are recommended to do the same.

Note that some functionality, such as |link, still operates exclusively
on the default session. Improvements in this area to follow soon.
