Enable inserts to the new MCR db schema in single slot mode only.
TODO:
- RELEASE NOTES
Notes:
- When in MIGRATION_WRITE_NEW or greater, deleting and then
restoring a page will result in different data in the revision table.
For example, if you delete a page that has text_ids present in the
revision table and restore it, the text_ids will be blank after.
- When in MIGRATION_WRITE_BOTH or greater the archive table will
start to ar_content_model entries where previously it would have been
given NULL. This is due to the old content schema having NULL in the db
when the default content model is used, but the new schema will always
have a value, taken from the content_models table
Note: If259b1e1c49ce was squashed into this change.

This introduces traits for testing different schema variations.
These are not very useful in this patch, but make it much easier
to add tests for MCR schema migration in subsequent patches.
The code in this patch was previously part of If259b1e1c49ceaa4.

This should have been done long ago. Now it is being done.
This also changes ar_text_id to NOT NULL, since it should never be null
anymore, and DEFAULT 0 in preparation for MCR stopping writing it.

Storing the user name or IP in every row in large tables like revision
and logging takes up space and makes operations on these tables slower.
This patch begins the process of moving those into one "actor" table
which other tables can reference with a single integer field.
A subsequent patch will remove the old columns.

This allows CommentStore to be added to MediaWikiServices
without the need of an aditional Factory.
This change includes a compatability layer to allow the behaviour
from 1.30 to continue to be used while deprecated.
CommentStore::newKey has been deprecated.
Keys are now passed into the public methods of CommentStore
where needed.
The following CommentStore methods have had their signatures changed
to introduced a $key parameter, but when used in conjunction with
CommentStore::newKey behaviour will remain unchanged:
* CommentStore::getFields
* CommentStore::getJoin
* CommentStore::getComment
* CommentStore::getCommentLegacy
* CommentStore::insert
* CommentStore::insertWithTemplate

There have been many issues with RevisionStore and titles due
to code paths that already know the title for a Revision not
passing the title into Revision in various ways or not passing
in the correct queryFlags.
The getTitle method now has a further fallback using Title::newFromID
and Title::GAID_FOR_UPDATE if not already attempted.
