util.prosodyctl.shell: Bring back banner set from config! I miss my custom ANSI-colored greeting!

net.connect: Propagate last error message from resolvers Previously it would only say "unable to resolve server" for all DNS problems. While "NoError in A lookup" might not make much sense to users, it should help in debugging more than the previous generic error. Friendlier errors will be future work.

s2smanager: Fire s2s-destroyed event to mirror s2s-created The existing events do not fire for unauthed sessions, for example (because the type does not match). I deemed changing their behaviour too risky, and the current behaviour may even be more desirable for some uses. This means we now have roughly paired events: - s2s-created -> s2s-destroyed (global only) - s2sin-established -> s2sin-destroyed (global + host) - s2sout-established -> s2sout-destroyed (global + host)

mod_c2s: Disconnect user sessions on a role change event The overlapping logic for deletion and password changed has been merged into a single function.

usermanager: Fire user-roles-changed event when updating roles of a local user
