We do not create historical UserMessage rows, for messages that didn't
have one, while marking messages as read and simply ignore those messages.
We do so because there is no user of creating UserMessage rows and it just
wastes storage.
Note that we still allow to mark messages from unsubscribed streams as
read but only those which have UserMessage rows for them to handle the
case when the unread messages were not marked as read while unsubscribing
from the stream due to some race condition. In such cases, messages
will not be included in the unread count shown in "All messages" menu
(and stream is anyways not present in the left sidebar), but the message
border on the left is green if viewing the stream after unsusbcribing it.
So, to avoid the confusion for users, the messages will be marked as read
when user scrolls down.
Previously, test cases or clients accessing /json/ views using HTTP
Basic Auth would be accepted, while we intended to only allow clients
authenticated with a session cookie to access these views.
This adds a check on the accessed path to avoid this possibility.
It seems unlikely that any API clients clients were taking advantage
of this unintended quirk; so we're not going to bother documenting
this bug fix as an API change. In any case, it should be trivial for
anyone affected to consult the documentation and then switch their
/json/foo URL to a correct /api/v1/foo URL.

Adds an API endpoint for accessing read receipts for other users, as
well as a modal UI for displaying that information.
Enables the previously merged privacy settings UI for managing whether
a user makes read receipts data available to other users.
Documentation is pending, and we'll likely want to link to the
documentation with help_settings_link once it is complete.
Fixes#3618.
