* DB changes
- Create a table for push topics NameTableStore
- Add a foreign key on subscriptions to normalize push topics
* Implement NameTableStore to normalize topics
* Update DB query joins to include topic from foreignkey
* Adapt code to use IDs instead of the actual topic

1) send apns topic when present in subscription metadata
2) check if subscription metadata is a valid JSON string
3) make epp_id column at echo_push_provider table auto_increment,
otherwise it will fail when trying to add a second row in the table

Updates the push subscription query to retrieve a provider string rather
than only its numeric internal ID.

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.
