This replaces the AppleDeviceToken table with a generic
PushDeviceToken with a `kind` field to make it easier to add functionality
like per-device/per-stream settings that share code between Android and
iOS devices.
The schema must continue to work on prod with the old table name, so we
add the new table in parallel and can drop the old table once this code
hits prod and any necessary data is copied.

ScheduledJobs with type Email displace the usual mandrill codepaths
in the Zulip Enterprise deploys
* Email-specific helper functions will appear in deliver_email.py

This was a precursor to UserMessage.flags.read that never got used
because we decided to use django-bitfield.

This commit must be simultaneously deployed on both staging and
prod0. It also requires completely taking down the app.
To deploy these changes, do:
* check out this commit at /root/zulip on postgres0, postgres1, staging, and prod0
* stop the process_fts_updates job on postgres0 and postgres1
* stop the app on staging and prod0
* do a puppet apply on postgres0, postgres1, staging, and prod0
* move the new client certificates into place on staging and app
* move the new server certificates into place on postgres0 and postgres1
* reload the database config on postgres0 and postgres1 (this might
actually require a restart)
* run tools/migrate-db on postgres0 as root
* do a deploy through this commit on staging and prod0
* start the process_fts_updates job on postgres0 and postgres1
* do a puppet apply on nagios

We need to run the schema migration manually using
"CREATE INDEX CONCURRENTLY upper_stream_name_idx ON zerver_stream ((upper(name)));"
since we need CONCURRENTLY and I seem to recall that doesn't work with South.
This significantly improves the uncached performance of get_stream()
(e.g. from 32ms to 9ms). At present, this codepath is not used
particularly heavily since we do cache the stream names and do most of
our filtering by recipient ID, but the index isn't expensive and does
provide a significant improvement in the uncached case.

We need to run the schema migration manually using
"CREATE INDEX CONCURRENTLY upper_subject_idx ON zerver_message ((upper(subject)));"
since we need CONCURRENTLY and I seem to recall that doesn't work with South.
Apparently our existing indexes on subject/topic weren't being used in
our narrowing queries, because we do case-insensitive search.
This substantially improves our database performance around
stream+topic narrows. See before and after query plans below from my
test instance.

In order to support iOS Push Notifications, we need to keep track
of a device's unique APNS Token. These are delivered to our iOS
code after registering for remote notifications
(imported from commit bbe34483e1380dc20a1c93e3ffa1fcfdb9087e67)
These engagement data will be useful both for making pretty graphs of
how addicted our users are as well as for allowing us to check whether
a new deployment is actually using the product or not.
This measures "number of minutes during which each user had checked
the app within the previous 15 minutes". It should correctly not
count server-initiated reloads.
It's possible that we should use something less aggressive than
mousemove; I'm a little torn on that because you really can check the
app for new messages without doing anything active.
This is somewhat tested but there are a few outstanding issues:
* Mobile apps don't report these data. It should be as easy as having
them send in update_active_status queries with new_user_input=true.
* The semantics of this should be better documented (e.g. the
management script should print out the spec above)x.

This commit CANNOT be deployed until the previous schema change
([schema] models: add an email_token field to Streams) is on prod.
Before applying this schema change, run the populate-stream-tokens
management command to generate tokens for streams that need them.
(imported from commit 7adc81c8c317ec5d59dd59ba42a4dc1a46174007)
The e-mail forwarder will use this. Set it to nullable temporarily to
accomodate existing streams; later commits will a) provide a script to
give all streams a token, and b) make the field non-null.
Realm administrators will eventually have a UI to regenerate stream
tokens.

This needs to be deployed to both staging and prod at the same
off-peak time (and the schema migration run).
At the time it is deployed, we need to make a few changes directly in
the database:
(1) UPDATE django_content_type set app_label='zerver' where app_label='zephyr';
(2) UPDATE south_migrationhistory set app_name='zerver' where app_name='zephyr';
