This is needed only because of the new MonadMask needed for bracket
in the new version. Ifdefing it everywhere is not practical, since the
Setup.hs uses it.
The hoary old HTTP library was only used when checking if an url exists,
when curl was not available. It had many problems, including not supporting
https at all.
Now, this is done using http-conduit for all urls that it supports. Falls
back to curl for any url that http-conduit doesn't like (probably ftp etc,
but could also be an url that its parser chokes on for whatever reason).
This adds a new dependency on http-conduit, but webdav support already
indirectly depended on that, and the s3-aws branch also uses it.
This opens up the possibility of using http-conduit for large file
downloads, but for now I've left it using wget/curl.

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.
This speeds up the webdav special remote somewhat, since it often now
groups actions together in a single http connection when eg, storing a
file.
Legacy chunks are still supported, but have not been sped up.
This depends on a as-yet unreleased version of DAV.

This only performs some basic tests so far; no testing of chunking or
resuming. Also, the existing encryption type of the remote is used; it
would be good later to derive an encrypted and a non-encrypted version of
the remote and test them both.

This version of wai changed the type of Middleware, so I cannot seem
to liftIO inside it. So, got rid of a lot of not really needed
complexity to use System.Log.Logger's logging stuff, and just use
the standard wai stdout logger when debug logging is enabled.
Format may change some, and it logs http to stdout instead of stderr
now. Doesn't matter for the webapp since both go to the same log anyway.
Motivation: Hook scripts for nautilus or other file managers
need to provide the user with feedback that a file is being downloaded.

Debian stable's warp-tls is too old to support the new https feature well,
so only use http with that old version.
Note that the webapp still depends on warp-tls, because the TLSSettings
type is used.
