The revision_actor_temp table has denormalized copies of rev_page and
rev_timestamp to support the actor indexes equivalent to
`actor_timestamp` and `page_actor_timestamp`. But to get these to be
used, we need to have the WHERE and ORDER BY use the denormalized fields
instead of the main revision-table fields.
We can take generally advantage of the fact that "ORDER BY field" uses
aliased field names before the names in the actual table, but WHERE
conditions do need to explicitly vary.

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.

MCR deprecated the Revision class in favor of the broadly similar
RevisionRecord, and more interestingly added the concept of multiple
content "slots" to revisions.
Thus, prop=revisions, prop=deletedrevisions, and so on gain a parameter
to specify which slots are wanted. When this new parameter is not
specified (and any content-related props are specified), a warning about
the legacy format will be issued.
The rest of the modules just needed to call methods or use constants on
RevisionRecord instead of Revision. ApiQueryDeletedrevs wasn't touched,
since it has been deprecated since 1.25 anyway.
This also updates a few non-query modules that don't depend on details
of editing, diffing, or viewing MCR revisions that haven't been figured
out yet.

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.

It is the job of git and svn to provide this information/metadata.
The form was different, some with short, some with long month name
some with leading zero at the day, some without.
The year is also present in the Copyright clause

Several classes have a "selectFields()" static method to tell callers
which fields to select from the database. With the recent comment table
change and the upcoming actor table change, this pattern has become too
simplistic as a SELECT will need to join several tables to be able to
retrieve all the needed fields.
Thus, we deprecate the selectFields() methods in favor of getQueryInfo()
methods that return tables and join conditions in addition to the
fields.

Undo traces of a practice we carried over from past projects and
existing examples that is neither universal nor actively encouraged in
the MediaWiki codebase.

Links generated by the API are now aware of the user's preferred
language and will show documents in that language if available.
To test, log in to mediawiki.org and set your language preference to 'es',
then on an MediaWiki installation with this patch view the generated
expanded API help at `api.php?action=help&recursivesubmodules=1&modules=main`.
Each link to documentation on mediawiki.org should take you to its
translated /es subpage, if one exists.

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.

This will allow extensions to inject into the query to implement
"xxshow" parameters, and to add additional properties to the output
data for "xxprop" parameters.
Also, call these new hooks from ApiQueryRevisions, ApiQueryAllRevisions,
ApiQueryUserContributions, and ApiQueryRecentChanges since I701e8e19 is
going to be wanting them.

Some generators (e.g. generator=recentchanges) in their default mode of
operation are particularly prone to not generating the same result set
on subsequent requests due to intervening activity on the wiki adding
new entries to the start of the list. We can mitigate this effect by
allowing such generators to provide "non-continuation" data to be used
if the generator isn't being continued.
ApiQueryRecentChanges and ApiQueryAllRevisions are updated to set this
new property. Other generators can easily be updated in the same way as
needed.
There isn't anything we can do about generators prone to having entries
added at random positions in the list rather than the beginning,
unfortunately.
