LoadBalancer uses Database::getDomainId() for deciding which keys to use
in the foreign connection handle arrays. This method should reflect any
changes made to the DB selection.
If the query fails, then do not change domain field. This is the sort of
approach that LoadBalancer is expects in openForeignConnection(). Also,
throw an exception when selectDB() fails.
The db/schema/prefix fields of Database no longer exist in favor of just
using the newer currentDomain field.
Also:
* Add IDatabase::selectDomain() method and made selectDB() wrap it.
* Extract the DB name from sqlite files if not explicitly provided.
* Fix inconsistent open() return values from Database subclasses.
* Make a relationSchemaQualifier() method to handle the concern of
omitting schema names in queries. The means that getDomainId() can
still return the right value, rather than confusingly omitt the schema.
* Make RevisionStore::checkDatabaseWikiId() account for the domain schema.
Unlike d2a4d614fc, this does not incorrectly assume the storage is
always for the current wiki domain. Also, LBFactorySingle sets the local
domain so it is defined even in install.php.
* Make RevisionStoreDbTestBase actually set the LoadBalancer local domain.
* Make RevisionTest::testLoadFromTitle() account for the domain schema.

During development a lot of classes were placed in MediaWiki\Storage\.
The precedent set would mean that every class relating to something
stored in a database table, plus all related value classes and such,
would go into that namespace.
Let's put them into MediaWiki\Revision\ instead. Then future classes
related to the 'page' table can go into MediaWiki\Page\, future classes
related to the 'user' table can go into MediaWiki\User\, and so on.
Note I didn't move DerivedPageDataUpdater, PageUpdateException,
PageUpdater, or RevisionSlotsUpdate in this patch. If these are kept
long-term, they probably belong in MediaWiki\Page\ or MediaWiki\Edit\
instead.

This adds getSecondaryDataUpdates and getDeletionUpdates
to ContentHandler, and updates WikiPage and DerivedPageDataUpdates
to handle DataUpdates from all slots.

This introduces a check that allows magic words like {{REVISIONUSER}}
to still work even when an incomplete fake RevisonRecord is provided to
RevisionRenderer. In such a case, the revision is loaded from the database
if needed. This lets old code that only has access to a Content object for
rendering use that Content object in a fake RevisionRecord, instead of
having to load the full revision from the database in all cases.

This allows optimization for situations in which a caller
needs the meta-data of a ParserOutput, and the respective
ContentHandler can provide that meta-data without generating
HTML output.

RevisionRenderer is the MCR replacement for Content::getParserOutput,
as outlined in <https://www.mediawiki.org/wiki/User:Daniel_Kinzler_(WMDE)/MCR-PageUpdater>.
Note: This change also introduces quite a bit of code for
merging ParserOutput objects.
