Erik Johnston 334e075dd8 Fix error when logging incomplete requests
If a connection is lost before a request is read from Request, Twisted
sets `method` (and `uri`) attributes to dummy values. These dummy values
have incorrect types (i.e. they're not bytes), and so things like
`__repr__` would raise an exception.

To fix this we had a helper method to return the method with a
consistent type.

Python 3 compatibility: make sure that we decode some byte sequences before we
use them to create log lines and metrics labels.

Richard van der Hoff be6527325a Fix exceptions when a connection is closed before we read the headers
This fixes bugs introduced in #3700, by making sure that we behave sanely
when an incoming connection is closed before the headers are read.

Richard van der Hoff eaaa2248ff Refactor request logging code
This commit moves a bunch of the logic for deciding when to log the receipt and
completion of HTTP requests into SynapseRequest, rather than in the request
handling wrappers.

Advantages of this are:
 * we get logs for *all* requests (including OPTIONS and HEADs), rather than
   just those that end up hitting handlers we've remembered to decorate
   correctly.

 * when a request handler wires up a Producer (as the media stuff does
   currently, and as other things will do soon), we log at the point that all
   of the traffic has been sent to the client.

...where the logger apparently recurses whilst trying to log the error, hitting the
maximum recursion depth and killing everything badly.

Richard van der Hoff b088aafcae Log number of events fetched from DB
When we finish processing a request, log the number of events we fetched from
the database to handle it.

[I'm trying to figure out which requests are responsible for large amounts of
event cache churn. It may turn out to be more helpful to add counts to the
prometheus per-request/block metrics, but that is an extension to this code
anyway.]

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 3d12d97415 Track DB scheduling delay per-request
For each request, track the amount of time spent waiting for a db
connection. This entails adding it to the LoggingContext and we may as well add
metrics for it while we are passing.
