Alex Vandiver cc9b028312 uploads: Set X-Accel-Redirect manually, without using django-sendfile2. 
The `django-sendfile2` module unfortunately only supports a single
`SENDFILE` root path -- an invariant which subsequent commits need to
break.  Especially as Zulip only runs with a single webserver, and
thus sendfile backend, the functionality is simple to inline.

It is worth noting that the following headers from the initial Django
response are _preserved_, if present, and sent unmodified to the
client; all other headers are overridden by those supplied by the
internal redirect[^1]:
 - Content-Type
 - Content-Disposition
 - Accept-Ranges
 - Set-Cookie
 - Cache-Control
 - Expires

As such, we explicitly unset the Content-type header to allow nginx to
set it from the static file, but set Content-Disposition and
Cache-Control as we want them to be.

The dependency graph of the requirements is as follows:

dev +-> prod +-> common
+
|
v
docs,pip

Of the files, only dev and prod have been used in the install scripts directly. The rest are implicit dependencies.

Steps to update a lock file, e.g. to update ipython from 5.3.0 to latest version:

  1. Remove entry for ipython==5.3.0 in dev.txt.
  2. Run ./tools/update-locked-requirements, which will generate new entries, pinned to the latest version.
  3. Increase PROVISION_VERSION in version.py.
  4. Run ./tools/provision to install the new deps and test them.
  5. Commit your changes.
