Richard van der Hoff 318711e139 Set Server header in SynapseRequest
(instead of everywhere that writes a response. Or rather, the subset of places
which write responses where we haven't forgotten it).

This also means that we don't have to have the mysterious version_string
attribute in anything with a request handler.

Unfortunately it does mean that we have to pass the version string wherever we
instantiate a SynapseSite, which has been c&ped 150 times, but that is code
that ought to be cleaned up anyway really.

Richard van der Hoff 645cb4bf06 Remove redundant request_handler decorator
This is needless complexity; we might as well use the wrapper directly.

Also rename wrap_request_handler->wrap_json_request_handler.

Richard van der Hoff 2a13af23bc Use run_in_background in preference to preserve_fn
While I was going through uses of preserve_fn for other PRs, I converted places
which only use the wrapped function once to use run_in_background, to avoid
creating the function object.

Richard van der Hoff 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.

Richard van der Hoff 7098b65cb8 Fix error on sqlite 3.7
Create the url_cache index on local_media_repository as a background update, so
that we can detect whether we are on sqlite or not and create a partial or
complete index accordingly.

To avoid running the cleanup job before we have built the index, add a bailout
which will defer the cleanup if the bg updates are still running.

Fixes https://github.com/matrix-org/synapse/issues/2572.

Erik Johnston 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.

Erik Johnston 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.

Mark Haines 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.

Erik Johnston 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.
