isRegistered is part of the slick UserIdentity interface, i.e.
it's the more "canonical" form. This change makes it a bit
easier to move away from using the huge (4000+ LOC) User class
everywhere, in favor of the UserIdentity interface, where
possible.
This patch is meant as a small step towards this goal. I tried
to replace some usages of User type hints already, but prefer
to go in small, incremental steps.

Adds DB tables for storing push subscriptions, some DB interaction code
for retrieving them within MediaWiki, and a set of API modules for
managing them from the outside world.
When testing this patch, be sure to run maintenance/update.php to create
the new tables, and set $wgEchoEnablePush = true in LocalSettings.php
to enable the API new API module.
N.B. The current DB schema is centered on app push subscriptions. Web
push subscriptions require slightly different handling, since they are
provided by browsers as a JSON blob rather than a token string. How to
handle web push subscriptions is a question we can defer until the time
comes to add web push support.
Subscription data is stored in the echo_push_subscription table, with
provider names normalized into the echo_push_provider table. We expect to
be looking up subscriptions by central user ID, so that column is indexed.
The subscription data also includes a column to store SHA256 digests of
the subscriber tokens. This is for use as a unique key constraint, since
we expect every push token to be univerally unique, and the token values
themselves may be too large to reasonably index in MySQL.
