This should enabled us, in the future, to enable support for mail
zephyrs without requiring users to re-auth.

The davidben-patched-for-roost Zephyr branch (available at
https://github.com/davidben/zephyr/tree/roost) adds Zephyr support for
these options. We also patch python-zephyr to expose them. These
basically let you save your Zephyr tickets and port number to a file,
so that you can later restore them (even potentially after the machine
rebooted). Basically because Zephyr is UDP, the Zephyr server will
continue trying to deliver messages to a particular port number that
was registered for up to 20 minutes after getting an error; so we can
even have downtime and reboot and still get our packets so long as we
restore the sessions within 20 minutes.

Our .crypt-table parsing code isn't quite correct, in that we don't
handle either the "zcrypt default" or "zcrypt by class/instance" pair
options (for sending messages in either direction) -- you have to be
zcrypting for an entire class. I think this makes sense given that on
the Zulip end we can only enforce anything on a stream level.

For now we only support the AES encryption type since the DES one is
probably not used anymore.

This must be deployed after we update our running nginx configuration
to serve api.humbughq.com.

Since in the future we might want requests to add subscriptions to
include things like colors, in_home_view, etc., we're changing the
data format for the add_subscriptions API call to pass each stream as
a dictionary, giving a convenient place to put any added options.
The manual step required here is updating the API version in AFS
available for use with the zephyr_mirror.py system.

At Ksplice we used /usr/bin/python because we shipped dependencies as Debian /
Red Hat packages, which would be installed against the system Python. We were
also very careful to use only Python 2.3 features so that even old system
Python would still work.
None of that is true at Humbug. We expect users to install dependencies
themselves, so it's more likely that the Python in $PATH is correct. On OS X
in particular, it's common to have five broken Python installs and there's no
expectation that /usr/bin/python is the right one.
The files which aren't marked executable are not interesting to run as scripts,
so we just remove the line there. (In general it's common to have libraries
that can also be executed, to run test cases or whatever, but that's not the
case here.)

This adds two characters to the length of our default format field, but
based on a conversation I had with kcr, I think this should probably be
okay. If it's a problem, the symptom we'll see is that certain people
will be unable to send zephyrs with this default format (so, certain
Humbug users will have their forwarding consistently fail).
We need to remember to, in a future commit (once everyone has started
using the updated version), remove the:
> or notice.format.endswith("@(@color(blue))")

Fixes#602.
I replaced the SIGKILL with a SIGINT, and then catch SIGINT with a
handler. This handler calls cancelSubs if necessary, and can later be
edited to perform other clean-up operations, too. I thought about, in
this same commit, changing the SIGTERM in
maybe_restart_mirroring_script to a SIGINT, but after tracing out the
code paths, I realized that isn't necessary. (The SIGTERM is
necessarily performed on a process that has not subscribed to any
zephyr classes, so cancelSubs is unnecessary. If we do think that we
may want to add additional clean-up operations in the future, though,
then it might be worth investigating changing this SIGTERM.)

Bots are not part of what we distribute, so put them in the repo root.
We also updated some of the bots to use relative path names.

Previously, if users of our code put the API folder in their pyshared
they would have to import it as "humbug.humbug". By moving Humbug's API
into a directory named "humbug" and moving the API into __init__, you
can just "import humbug".

This was causing about 10% of the time, personals being forwarded by
tabbott/extra@ATHENA.MIT.EDU to get this error:
zwrite: Field too long for buffer while sending notice to
tabbott/extra@ATHENA.MIT.EDU
We don't fully understand the cause of the problem, but this fixes it.

The refactoring that we did a couple weeks ago to make the zephyr
mirror script restart itself automatically (by splitting it into
zephyr_mirror.py and zephyr_mirror_backend.py) had a poor interaction
with our code for killing old zephyr_mirror processes (to prevent
double-mirroring). If you manually ran two copies of the outer
mirroring script (zephyr_mirror.py), then the second one would on
startup kill the first one's zephyr_mirror_backend.py children (for
being duplicate zephyr_mirror_backend.py processes that would result
in double-mirroring). However, importantly, it did not kill the first
mirroring script's zephyr_mirror.py parent process, so the first
mirroring script would then proceed to startup up new children. The
process then repeats, with the two scripts' roles reversed.
This issue didn't affect the sharded mirroring case, where I had been
doing the testing of the kill code with that refactoring, because we
don't have a version of the outer zephyr_mirror.py loop for that
situation (a consequence of it being hard to restart the threads
properly with the run_parallel API that we're using to spawn all the
children).

This is probably a lot more annoying to use, in that e.g. there are
separate log files for the two directions of the mirror, but we
haven't used these logs for much, so whatever.
