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 .

Cache failures in url_preview handler
...
Reshuffle the caching logic in the url_preview handler so that failures are
cached (and to generally simplify things and fix the logcontext leaks).

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.

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.

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.

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.
