THE CENSUS OF HUMBUG
Now it happened that at this time Waseem Daher issued a decree that
a census should be made of the whole users of Humbug.
This census -- the first -- took place while Faraone was governor of
MailChimp, and everyone went to be registered, each to his own realm.
So Alice Humbugger set out from the town of MIT for MailChimp in order to
be registered.

This refactoring basically splits off two functions from update_unread_counts(),
which then becomes a simple three-liner.
The function get_unread_counts() is extracted, and it's purely functional
computation. It paves the way for a more pull-based approach to getting "unread"
counts, where other parts of the program can just call it to get values as
needed without worrying about side effects. It is staying in zephyr.js for
now.
The other function is stream_list.update_dom_with_unread_counts(), which
has a new home in stream_list.js. It handles all the DOM manipulation
aspect of unread counts in the left pane, mostly by delegating to smaller
functions within stream_list. Some of those smaller functions can now
be turned into private methods FWIW, but I'm not sure it's worth the
trouble.

This is a prefactoring to eventually eliminate the home_unread_messages
global variable. More commits to follow.
In order to set up process_loaded_for_unread() not to modify
global variable to get its job done, we want to pull it out of
add_messages(), so that add_messages() doesn't have to pass back
state to the 9 different places in the codebase where it's called.
There are only 2 places where process_loaded_for_unread() get
called after this commit.
In order to facilitate pulling up process_loaded_for_unread(), I
made it so that the contract for add_messages() was to accept
already-hydrated messages. This way I could hydrate the messages
before calling process_loaded_for_unread() without have to
worry about double-caching them in add_messages. This will
slightly improve performance, but it was mostly done for code
clarity.

This was a workaround for a number of other bugs we had, but at this
point just serves to make debugging more difficult.

Since we log to statsd our cache time lookups by cache key, using a unique
tweet id for each lookup was just filling up our cache without being useful.
Also, log database cache lookups in a further namespace to distinguish between
memcached caches

Users can send to any stream except invite-only streams that they
aren't subscribed to. Bots can send to any stream except invite-only
streams that neither they nor their owner is subscribed to.

We really should not be storing bot API keys in the DOM and should
require some sort of additional authentication before showing them,
but this seems reasonable for a first pass.

Previously a default was missing from this function, which resulted in
users being unable to change their settings if they tried to disable
sounds.

After this change, the memcached time consumed by doing
get_old_messages for 200 and 1000 messages respectively now look like
this:
200 63ms (mem: 6ms/3) (db: 4ms/2q) /json/get_old_messages
200 178ms (mem: 67ms/2) (db: 6ms/1q) /json/get_old_messages
which might help explain where the time is going on prod for some of
our slower queries.
(imported from commit b8fe83b175914b6796922a65a1c5537f4e7a9429)
The default is 50, which we believe was causing too much CPU
contention in prod during restarts. This commit lowers the max to 20.
The django-command-line script needs to be restarted manually to pick
up this change.

The idea here being: if there's only one line, it discourages
me from writing a long message (and also makes me think that
enter will send).

This commit takes control of keyboard-based pagination away
from the browser, so that we can use the effective viewport
size as the amount to page, as well as keeping a little bit
of overlap from page to page. There had been issues with
pagination for a while, but the introduction of the always-open
composebox particularly aggravated the situation.
