This commit changes APIs and requires and update of all zephyr
mirroring bots to deploy properly.

This improves the throughput of mirroring a large number of zephyrs in
a row from about 1.5/second to about 9/second, which is basically
satisfactory.

Personals are now just private messages between two people (which
sometimes manifests as a private message with one recipient). The
new message type on the send path is 'private'. Note that the receive
path still has 'personal' and 'huddle' message types.

Previously messages sent to zephyr instance " " wouldn't be forwarded
zephyr=>humbug because the target instance is the null instance; I
learned this when we got a few tracebacks in the zephyr_mirror log, so
clearly this does happen.

This is useful for trying out new versions of the forwarding code
while the mirroring bot is still running in production.

Previously we were spending 15 seconds on linerva (and more like 2.5
minutes on the not-yet-operational zmirror.humbughq.com) to subscribe
to all of our streams.
(imported from commit c36cb1c26868f142683d9c92d4875fcd4931886e)
We've had multiple requests from MIT zephyr users to allow
non-alphanumeric stream names, and we haven't decided what we want to
allow, so for now allow everything.
Note that the web client and mirror script limit stream names to 30
characters, which is our database limit.

Zephyr has this great property where a small fraction of the time, the
Zephyr server rejects your attempt to subscribe to something for no
particular reason, returning a "SERVNAK" error.

This does introduce a small security issue, in that a shell with
expired AFS tokens on the machine running the mirroring script will be
able to read the Humbug API key using /proc/pid/environ. I think this
is fine -- you can steal the API key from a running process using
ptrace anyway.

Because in the zephyr world, people often manually linewrap their
zephyrs, we need to relax the algorithm's assumption that every line
was wrapped to the same linewrapping threshhold. Otherwise messages
that look like this:
aaaaa aaaaa aaaaa aaaaaaaaaa aaaaa aaaaa aaaaa aaaaa
aaaaa aaaaa aaaaa aaaaaaaaaa aaaaa aaaaa aaaaa aaaaa aaaaa aaaaaa
aaaaa aaaaa aaaaa aaaaaaaaaa aaaaa aaaaa aaaaa aaaaa
might be treated as a paragraph break, even though that was unlikely
to have been the sender's intention.
