ChronologyProtector uses these classes to briefly store positions
and everytime the fields change then errors can happen when old
values are unserialized and used. Use a simple two-element map
format for serialized positions. The fields are recomputed back
from the data map.
Values from before this change will issue the warning
"Erroneous data format for unserializing". To avoid that, bump
the ChronologyProtector key version. Future field changes will
not require this.
This change should be deployed on all wikis at once.

The binlog file/pos where only being used in __toString() for the GTID
case. Make that method use the GTID set instead and avoid querying the
old-fashioned binlog fields all together in that case. The STATUS
queries involve some global lock contention.

* Update replace()/upsert() to combine the affected row
count for the non-native case
* Also make replace() atomic in the non-native case,
similar to how upsert() already works

This PHP extension was deprecated in PHP 5.5 and removed in PHP 7.0.
The newer MySQL driver 'mysqli' is the default driver since MediaWiki
1.22 and 'mysql' was deprecated in MediaWiki 1.30.

In the off chance something called this, it would break all
sorts of code that expects that either query result functions
either succeed or throw an error.
Callers are not expected to have to check if the result of
a query is meaningful or false due to an error.

* Move DatabaseTest and DatabaseSQLTest to libs,
and remove MediaWikiTestCase dependency.
* Refactor DatabaseTest to be a test of the Database abstract class,
not of whatever current DB backend is configured by LocalSettings.
- Remove most switches/conditionals and other tests for specific
database backends. Move those to individual test classes for
those backends instead.
- Some tests appear to have been integration tests for the PHP driver
and/or the db backend itself. Moved to a new DatabaseIntegrationTest.
- Now that only the abstract Database is invoked, the test runs a bit
faster (no real connections/queries).
* Add missing @covers tags, and remove or fix broken ones
(follows-up 26e52f0c49).
