Having such comments is worse than not having them. They add zero
information. But you must read the text to understand there is
nothing you don't already know from the class and the method name.
This is similar to I994d11e. Even more trivial, because this here is
about comments that don't say anything but "constructor".

selectField() and selectFieldValues() are trivial, they just need to
pass it through to select(). In fact, selectFieldValues() was already
doing it, just no one ever updated IDatabase.
insertSelect() is a little more work. nativeInsertSelect() was
originally written as largely a copy-paste of select() and has since
gotten well out of sync. Now that we have selectSQLText(), we should be
able to just use that. DatabasePostgres's implementation can wrap the
parent implementation instead of being another copy-paste, but
DatabaseOracle seems to still need to be special.

In PostgresSQL
a) Temp tables are automatically deleted upon end of session
b) Same temp table name hides existing table for current session
It is not necessary to consider 'postgres' during dropping of table.
I guess similar logic for Oracle but I could not verify.
It seems that no one use Oracle for MediaWiki.

Introduce a service to represent wfReadOnly() and friends.
It's necessary to have two service instances, one for wfReadOnly() and
one for wfConfiguredReadOnlyReason(), to avoid a circular dependency,
since LoadBalancer needs the configured reason during construction, but
wfReadOnly() needs to query the currently active load balancer.
Not having a cache of the configuration makes it possible to dynamically
change the configuration. Ideally things would not change the
configuration, and I removed such instances in core, but to support
extensions, I added a test ensuring that the configuration can be changed.

On Travis CI, the Postgres build has been failing very early on
in the installer (before phpunit) due to a database error:
> Creating administrator user account.. DBQueryError at Database.php:1059
> Query: SELECT user_id FROM "user" WHERE user_name = 'Admin' LIMIT 1
> Function: User::idForName
> Error: 42P01 ERROR: relation "user" does not exist
> LINE 1: SELECT /* User::idForName */ user_id FROM "user" ...
This is because the installer makes its own Database object without
involving ServiceWiring or MWLBFactory, which means wgDBport and
(more importantly) 'keywordTableMap' don't get applied.
While keywordTableMap doesn't matter during the database installation,
after the installer is done updating GlobalVarConfig and resetting
MediaWikiServices, DatabaseInstaller::enableLB takes that homemade
connection and injects it into MediaWikiServices by redefining
the 'DBLoadBalancerFactory' service. Which then affects all use
of wfGetDB(), such as from User::idForName().

It's unreasonable to expect newbies to know that "bug 12345" means "Task T14345"
except where it doesn't, so let's just standardise on the real numbers.

Leave \Blob as an alias. Callers can now use the Rdbms\Blob class
for "extends"/"new" and the Rdbms\IBlob interface for type hints.

Use of &$this doesn't work in PHP 7.1. For callbacks to methods like
array_map() it's completely unnecessary, while for hooks we still need
to pass a reference and so we need to copy $this into a local variable.

Most of these are simply changing annotations to reflect
reality. If a function can return false to indicate failure
the @return should indicate it.
Some are fixing preg_match calls, preg match returns 1, 0 or false,
but the functions all claim to return booleans.
This is far from all the incorrect return types in mediawiki, there
are around 250 detected by phan, but have to start somewhere.

This is useful when IMaintainableDatabase methods are needed

Also:
* Set visibility for ExternalStoreDB methods.
* Cleaned up various type hints and comments.

This works by setting a callback to return the cache set
options. The callback will watch DB reads and create a
merged result from said usage.
This handles callers that are missing getCacheSetOptions().

It's no longer an LBFactory subclass (since 5d4b009cf), and the MW-prefix
seems more natural for this class.
The class has only existed since for about 2 weeks (since 0e5cd18b7) and
is not used outside MediaWiki core across Wikimedia Git.

Pretty much everything seems to assume that PHP booleans should be
converted to 0/1: MySQL does this implicitly thanks to the lack of
strict mode by default, while PostgreSQL and Sqlite (and Mssql) do it
explicitly.
The addition of MySQL strict mode for unit tests in Ib2873913 exposed
the assumption in the case of MySQL by making some extension unit tests
fail. So let's make casting bool to int the default behavior of
Database::addQuotes().
This also cleans up the phpdoc for Database::addQuotes() to properly
reflect all the supported types that can be passed to it.

These DatabaseBase methods have no callers are were a mistake to
begin with. They only encouraged code forking and incompatibilities
among different backing DB types.
Also removed stray realTimestamps() method that was left over
from prior removals.

* Move almost all the code to LBFactoryMW and inject the main config.
* Make LBFactoryMW no longer extend anything, which is now pointless.
* Let site admins explicitly set "servers" and "externalServers" arrays.
* Pass in the $wgDBschema field regardless of $wgDBtype. It defaults to
null, so no one would bother setting it if they did not want to use it.
