9255a6cb17 Improve exception handling for background processes
There were a bunch of places where we fire off a process to happen in the
background, but don't have any exception handling on it - instead relying on
the unhandled error being logged when the relevent deferred gets
garbage-collected.

This is unsatisfactory for a number of reasons:
 - logging on garbage collection is best-effort and may happen some time after
   the error, if at all
 - it can be hard to figure out where the error actually happened.
 - it is logged as a scary CRITICAL error which (a) I always forget to grep for
   and (b) it's not really CRITICAL if a background process we don't care about
   fails.

So this is an attempt to add exception handling to everything we fire off into
the background.

4f40d058cc Replace old-style raise with six.reraise
The old style raise is invalid syntax in python3. As noted in the docs,
this adds one more frame in the traceback, but I think this is
acceptable:

    <ipython-input-7-bcc5cba3de3f> in <module>()
         16     except:
         17         pass
    ---> 18     six.reraise(*x)

    /usr/lib/python3.6/site-packages/six.py in reraise(tp, value, tb)
        691             if value.__traceback__ is not tb:
        692                 raise value.with_traceback(tb)
    --> 693             raise value
        694         finally:
        695             value = None

    <ipython-input-7-bcc5cba3de3f> in <module>()
          9
         10 try:
    ---> 11     x()
         12 except:
         13     x = sys.exc_info()

Also note that this uses six, which is not formally a dependency yet,
but is included indirectly since most packages depend on it.

d5352cbba8 Handle url_previews with no content-type
avoid failing with an exception if the remote server doesn't give us a
Content-Type header.

Also, clean up the exception handling a bit.

Add federation_domain_whitelist option (#2820)
Add federation_domain_whitelist

gives a way to restrict which domains your HS is allowed to federate with.
useful mainly for gracefully preventing a private but internet-connected HS from trying to federate to the wider public Matrix network

ad7ec63d08 Use the right path for url_preview thumbnails
This was introduced by #2627: we were overwriting the original media for url
previews with the thumbnails :/

(fixes https://github.com/vector-im/riot-web/issues/6012, hopefully)
