Reshape Idavoll as a PubSubResource.
PubSubResource is Wokkel's newer interface for building (parts of) XMPP
publish-subscribe services and replaces the old interface of PubSubService. It
is more flexible for adding new protocol, allows for node-as-code (providing a
specific backend per node), and permits accepting requests for different
entities (virtual hosts or PEP-like settings).
This moves over the current backend to use the new interface, so new code for
previously unsupported protocol can be added down the line.

| 208 | 1 Upgrading |
| 2 ========= | |
| 3 | |
| 4 To 0.8.0 | |
| 5 ======== | |
| 6 | |
| 7 This release includes an optional HTTP interface with a gateway to subscribe | |
| 8 to remote nodes. The subscriptions and associated callbacks are stored in | |
| 9 the database if the PostgreSQL storage backend is used. This requires a new | |
| 10 table, of which the schema is in db/gateway.sql: | |
| 11 | |
| 12 psql -e pubsub <db/gateway.sql | |
| 13 | |
| 14 The schema of the other tables has also changed significantly compared to | |
| 15 0.7.3 and older. For these changes, there is an upgrade script in the form | |
| 16 of a series of SQL statements to be run against an database with the older schema: db/to_idavoll_0.8.sql, like so: | |
| 17 | |
| 18 psql -e pubsub <db/to_idavoll_0.8.sql |
