I would prefer to be testing the attribute itself rather than the
version, but it's not easy to access without an actual request object,
and I'd prefer to compute this once-and-for-all on startup, rather
than on each request, since the latter just seems fragile.

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.

My previous commit (fbdc092029bbafea716e27fbb99fec58a6f24392)
incorrectly specified that you must have a version of python-requests
greater than 0.12.1, when it should be a >= relation since 0.12.1 is
sufficient.

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".

The old-style api.humbug is deprecated, so we rewrite the path for things

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.

Sometimes the very first message we send isn't received by
python-zephyr; this could be because of our growing a 17-message queue
of zephyrs to service, so let's not do that.

This ensures that Humbug receives the verbatim text of the Nagios
body, rather than a slightly modified version. Tested by running
manually.

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.

Previously all that we logged was the sender, which turns out to be a
constant for humbug=>zephyr mirroring.

feedback-bot and zephyr_mirror will need to be updated and restarted

Features include:
* Not forking into two processes (shells out to zwrite to send
instead). This makes life easier since we're not doing concurrent
programming.
* Eliminated a lot of hard-to-read or unnecessary debugging output.
* Adding explanatory test suggesting the likely problem for some
common sets of received messages.
* Much less code duplication.
* Support for testing a sharded zephyr_mirror script (--sharded).
* Use of the logging module to print timestamps -- makes debugging
some issues a lot.
* Only one sleep, and for only 10 seconds, between sending the
outgoing messages and checking that they were received.
* Support for running two copies of this script at the same time, so that
running it manually doesn't screw up Nagios.
* Passed running 100 tests run in a row.

We should be canonicalizing stream names to class names in
update_subscriptions_from_humbug, before we even decide which classes
to subscribe to; otherwise deduplication and tracking of which classes
we're already subscribed to won't work.

This causes e.g. call_on_each_message to switch to dont_block mode
after the first error.

Also fixes bugs where the retry code wouldn't work correctly if
verbose wasn't set, prints out which API query had the error, and is
more consistent about printing something to end the "..." sequences.

Previously, we were sending "Skipping message we got from Humbug!"
for messages we wouldn't have forwarded anyway.

In this case, if we're configured to not forward personals, there's no
point in logging a decision not to forward one.

It seems that check-mirroring was reporting a lot of spurious failures
due to it sometimes taking more than 3 seconds for the setup phase of
check-mirroring's receive path to run. So fix this:
(1) Wait a bit more than 3 seconds for the receiver to subscribe to
messages
(2) Subscribe to Humbug messages before forking (we can't do this with
zephyr.init() because python-zephyr gets totally messed up if you use
it from multiple processes with a shared initialization)
(3) Get rid of the old time.sleep(0.x) values that were intended to
make messages arrive in order -- since we're now checking that
messages correctly arrived using set(), they aren't needed.
(4) Use a single request to subscribe to both zephyr classes we need
to subscribe to (saves 1 RTT).
