The point of the lock is to prevent two deployments happening at the
same time and racing with each other, not to prevent doing any future
deployments after an error happens (which is what the current
implementation does in practice).
Addresses part of #208.
The #! line processing interpreted the argument to pass to `env` as
"python2.7 -u", which obviously isn't a real program.
We fix this by setting the PYTHONUNBUFFERED environment variable
inside the program, which has the same effect.
Thanks to Dan Fedele for the bug report and suggested solution!
update-deployment has been replaced by upgrade-zulip for local server
instances, since it won't be running off a git repository, and
update-prod-static won't be needed since we plan on shipping minified
javascript.
When we deploy this, the deployment will fail, and then we'll need to
update the git checkout from which post-receive runs on git.zulip.net.

This may require just doing an mv on the home directory, plus changing
the home directory in /etc/passwd. It should of course be done carefully.

This is a big change affecting lots of areas:
* Pipeline no longer deals with JS (though it still minifies CSS)
* A new script, tools/minify-js (called from update-prod-static),
minifies JavaScripts
* A command-line argument --prev-deploy, if passed to minify-js or
update-prod-static, is used to copy minified JS from a previous
deploy (i.e., a previous git checkout), if the source files have
not changed
* update-deployment passes --prev-deploy
* Scripts are now included with the minified_js template tag, rather
than Pipeline's compressed_js
Also, as a side benefit of this commit, our Handlebars templates will
no longer be copied into prod-static/ and accessible in production.
Unminification is probably broken, but, per Zev and Trac ticket #1377,
it wasn't working perfectly before this change either.
(Based on code review, this commit has been revised to:
* Warn if git returns an error in minify-js
* Add missing output redirects in update-prod-static
* Use DEPLOY_ROOT instead of manually constructing that directory
* Use old style formatting)

Since update-deployment is run on the host being deployed to and only
has access to a recent clone of the git repository, it doesn't
necessarily have the old refs available for reverts.

This requires manual steps on deploy to each of staging and prod:
(1) Run the new update-deployment code to setup the initial deployment directory.
(2) Restart all the programs running in screen sessions.
(3) Deploy the nginx changes and restart nginx.

We leave the stuff under api/ alone for now, since we need to be able to ship
it as a standalone thing.
tools/post-receive wasn't using the function anyway.
For push to master: Push this commit, update post-receive per instructions at
the top of that file, then push the rest of the branch to confirm that the hook
still works.
No manual instructions for prod.

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 uses pylibmc, the same memcached client library we use from Django. If
that becomes a problem for whatever reason, all we really need to do is send
"flush_all\n" to TCP port 11211 on localhost.

After this commit, we're tracking two branches: "master" and "prod".
Pushed to "prod" deploy to production, while pushes to "master" deploy
to the staging server.
