Newer syntax
attr.ib(factory=dict)
is just a syntactic sugar for
attr.ib(default=attr.Factory(dict))
It was introduced in newest version of attrs package (18.1.0)
and doesn't work with older versions.
We should either require minimum version of attrs to be 18.1.0,
or use older (slightly more verbose) syntax.
Requiring newest version is not a good solution because
Linux distributions may have older version of attrs (17.4.0 in Fedora 28),
and requiring to build (and package)
newer version just to use newer syntactic sugar in only one test
is just too much.
It's much better to fix that test to use older syntax.

Previously we only queried the device list when the user joined the room; now we
do it when they are invited too. This means that new messages can be encrypted
for the devices of the invited user as of the point they were invited.
WARNING: This commit has two major problems however:
1. If the invited user adds devices after being invited but before joining, the
device-list will not be updated to the other servers in the room (as we don't
know who those servers are).
2. This introduces a regression, as previously the device-list would be correctly
updated when when user joined the room. However, this resync doesn't happen
now, so devices which joined after the invite and before the join may never
be added to the device-list.
This is being merged for DINSIC given the edge case of adding devices between
invite & join is pretty rare in their use case, but before it can be merged to
synapse in general we need to at least re-sync the devicelist when the user joins
or to implement some kind of pubsub mechanism to let interested servers subscribe
to devicelist updates on other servers irrespective of user join/invite membership.

We need to do a bit more validation when we get a server name, but don't want
to be re-doing it all over the shop, so factor out a separate
parse_and_validate_server_name, and do the extra validation.
Also, use it to verify the server name in the config file.
a61738b removed a call to run_on_reactor from a unit test, but that call was
doing something useful, in making the function in question asynchronous.
Reinstate the call and add a check that we are testing what we wanted to be
testing.
Make sure that server_names used in auth headers are sane, and reject them with
a sensible error code, before they disappear off into the depths of the system.
