Removed old extensible-exceptions, only needed for very old ghc.
Made webdav use Utility.Exception, to work after some changes in DAV's
exception handling.
Removed Annex.Exception. Mostly this was trivial, but note that
tryAnnex is replaced with tryNonAsync and catchAnnex replaced with
catchNonAsync. In theory that could be a behavior change, since the former
caught all exceptions, and the latter don't catch async exceptions.
However, in practice, nothing in the Annex monad uses async exceptions.
Grepping for throwTo and killThread only find stuff in the assistant,
which does not seem related.
Command.Add.undo is changed to accept a SomeException, and things
that use it for rollback now catch non-async exceptions, rather than
only IOExceptions.

the regular host if they all fail.
gmail.com has some XMPP SRV records, but does not itself respond to XMPP
traffic, although it does accept connections on port 5222. So if a user
entered the wrong password, it would try all the SRVs and fall back to
trying gmail, and hang at that point.
This seems the right thing to do, not just a workaround.
