170ccc9de5 Fix routing loop when fetching remote media 
When we proxy a media request to a remote server, add a query-param, which will
tell the remote server to 404 if it doesn't recognise the server_name.

This should fix a routing loop where the server keeps forwarding back to
itself.

Also improves the error handling on remote media fetches, so that we don't
always return a rather obscure 502.

48b5829aea Fix up preview URL API. Add tests. 
This includes:

- Splitting out methods of a class into stand alone functions, to make
  them easier to test.
- Adding unit tests to split out functions, testing HTML -> preview.
- Handle the fact that elements in lxml may have tail text.

aecaec3e10 Change the way we summarize URLs 
Using XPath is slow on some machines (for unknown reasons), so use a
different approach to get a list of text nodes.

Try to generate a summary that respect paragraph and then word
boundaries, adding ellipses when appropriate.

eb79110beb Clean up the blacklist/whitelist handling. 
Always set the config key with an empty list, even if a list isn't specified.
This means that the codepaths are the same for both the empty list and
for a missing key. Since the behaviour is the same for both cases this
makes the code somewhat easier to reason about.

43f0941e8f Split out BaseMediaResource into MediaRepository 
This is so that a single MediaRepository can be shared across all
resources, rather than having a "copy" per resource.

In particular this allows us to guard against both the thumbnail and
download resource triggering a download of remote content at the same
time.

42aa1f3f33 Merge pull request #478 from matrix-org/daniel/userobject 
Introduce a User object

I'm sick of passing around more and more things as tuple items around
the whole world, and needing to edit every call site every time there is
more information about a user. So pass them around together as an
object.

This object has incredibly poorly named fields because we have a
convention that `user` indicates a UserID object, and `user_id`
indicates a string. I tried to clean up the whole repo to fix this, but
gave up. So instead, I introduce a second convention. A user_object is a
User, and a user_id_object is a UserId. I may have cried a little bit.

2110e35fd6 Introduce a Requester object 
This tracks data about the entity which made the request. This is
instead of passing around a tuple, which requires call-site
modifications every time a new piece of optional context is passed
around.

I tried to introduce a User object. I gave up.

This follows the same flows-based flow as regular registration, but as
the only implemented flow has no requirements, it auto-succeeds. In the
future, other flows (e.g. captcha) may be required, so clients should
treat this like the regular registration flow choices.
