Turn _start_key_lookups into an inlineCallbacks function
...
... which means that logcontexts can be correctly preserved for the stuff it
does.
get_server_verify_keys is now called with the logcontext, so needs to
preserve_fn when it fires off its nested inlineCallbacks function.
Also renames get_server_verify_keys to reflect the fact it's meant to be
private.

Fix potential race in _start_key_lookups
...
If the verify_request.deferred has already completed, then `remove_deferreds`
will be called immediately. It therefore might resolve the server_to_deferred
deferred while there are still other requests for that server in flight.
To avoid that, we should build the complete list of requests, and *then* add the
callbacks.

Consistency for how verify_request.deferred is called
...
Define that it is run with no log context, and make sure that happens.
If we aren't careful to reset the logcontext, we can't bung the deferreds into
defer.gatherResults etc. We don't actually do that directly, but we *do*
resolve other deferreds from affected callbacks (notably the server_to_deferred
map in _start_key_lookups), and those *do* get passed into
defer.gatherResults. It turns out that this way ends up being least confusing.

pull out handle_key_deferred to top level

There's no need for this to be a nested definition; pulling it out not only
makes it more efficient, but makes it easier to check that it's not accessing
any local variables it shouldn't be.
