We don't want to be doing .well-known lookups on these guys.

This is going to get too big and unmanageable.

Turns out that the library does a better job of parsing URIs than our
reinvented wheel. Who knew.

There are two things going on here. The first is that, unlike
parse_server_name, URI.fromBytes will strip off square brackets from IPv6
literals, which means that it is valid input to ClientTLSOptionsFactory and
HostnameEndpoint.

The second is that we stay in `bytes` throughout (except for the argument to
ClientTLSOptionsFactory), which avoids the weirdness of (sometimes) ending up
with idna-encoded values being held in `unicode` variables. TBH it probably
would have been ok but it made the tests fragile.

Require event format version to parse or create events

Disable native upsert on sqlite

If you use double-quotes here, you have to escape your backslashes. It's much
easier with single-quotes.

(Note that the existing double-backslashes are already interpreted by python's
""" parsing.)

Move the Host header logic down here so that (a) it is used if we reuse the
agent elsewhere, and (b) we can mess about with it with .well-known.
