We previously sent our client type to the server as a GET/POST parameter
of "client=<something>", most commonly "client=API: Python".
We switch here to providing the same information as a User-agent header
sent on each request, which is more standards-compliant.
Also added is some data about the platform the user is using. If your
client string was set to "MyLittleZulip/1.0", the resultant string could
look something like this:
MyLittleZulip/1.0 (Ubuntu; 12.04)

Previously it only provided the list of all public streams; now it
allows one to specify any union of some of the following:
* all public streams
* all streams the user subscribed to
(the most relevant being the union of those two, which is what we want
for the "streams" page).
Or:
* all streams in realm (superuser only)
The manual task required is that when this is pushed to prod, we need
to also deploy the new sync-public-streams version to zmirror.

When we deploy this, we'll need to of course actually build and deploy
the new API tarball.
