test_ipaddrs.py had an invalid regexp, caught by the latest version of flake8
The new flake8 complains about both W503 (line break inside a conditional
before a binary operator) and W504 (line break *after* the operator). I think
break-before is the new preferred style, but for now I'm just going to ignore
them both and leave the code alone.
This establishes what our mailbox protocol does to encrypt the
individual (post-SPAKE2) messages, which combines NaCl SecretBox and our own
key-derivation choices. I'd like to move off of NaCl/libsodium and I think
some RFC7539-implementing library might be compatible, and with these test
vectors I can check that. I also want to copy these tests into the Rust port.
I tested this locally (on MacOS) against python3.7.0, and it now works. This
will appear broken on travis/appveyor until those CI environments add support
for py3.7 (but the failures should be ignored since py3.7 is in the
'allowed_failures' list).

See https://bugs.python.org/issue26175 . tempfile.SpooledTemporaryFile
doesn't fully implement the IOBase abstract class, which breaks because
py3.7.0's new zipfile module tries to delegate .seekable down to the wrapped
file and causes an AttributeError.

The servers were moved out to separate repos (magic-wormhole-mailbox-server
and magic-wormhole-transit-relay), and I think this Dockerfile was building
an image mostly to run the mailbox server.
It might make sense in the future to have a Docker image for just the client,
in which case it'll be time to bring these Dockerfiles back with different
contents.

The flake8 config excludes E741, which would complain about using
'l' (lower-case ell) as a variable name. We use this for the Lister object in
one test that uses single-character variable names for all the machines ('b'
for Boss, 'm' for Mailbox, etc). That comment was added before excluding
E741. If we ever restore that warning, we might want to rename the variable.
We care about how long it takes to import all the wormhole-specific things,
to investigate user-perceived latency from the time the command is launched
to the time they can actually interact with it. So we need to record
`time.time()` before doing the rest of the imports, even though pep8 says all
imports should be done before any non-importing statements.
