For some unknown reason, when the `actor` table has few enough rows (or
few enough compared to `revision_actor_temp`) MariaDB 10.1.37 decides it
makes more sense to fetch everything from `actor` + `revision_actor_temp`
and filesort rather than fetching the limited number of rows from
`revision_actor_temp`.
We can work around it by telling it to not reorder the query, but then
(unlike in I9da981c0) we also have to reorder it ourselves to put
`revision_actor_temp` first instead of `revision`.

Remove many references to database fields rev_text_id and ar_text_id,
which are being retired as part of MCR Schema Migration.
Some references remain, and will be removed under other patchsets
or other tasks.

When querying by user name or actor ID, the partitioning on the
'contributions' replicas makes things worse rather than better.

This was originally a global search and replace. I manually checked all
replacements and reverted them if (due to the lack of type hints) either
null (that would be 0 when counted) or a Countable object can end in the
variable or property in question.
Now this patch only touches places where I'm sure nothing can break.
For the sanity of the honorable reviewers this patch is exclusively touching
negated counts. You should not find a single `!== []` in this patch, that
would be a mistake.

When this was originally written, the plan was to read both the old and
new fields during the transition period, while stopping writes to them
midway through. It turns out that the WHERE conditions to do read-both
correctly are generally not handled well by the database and working
around that would require a lot of complicated code (see what's being
removed from ApiQueryUserContribs here, for example).
We can simplify things greatly by instead having it write both fields
during the transition period, reading from the old for the first part
and the new for the second part, as is being done for MCR.

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.

Uses new PHP 5.6 syntax like ...parameter unpacking and
calling anything looking like a callback to make the code more readable.
There are much more occurrences but this commit is intentionally limited
to an easily reviewable size.
In one occurrence, a simple conditional instead of trickery was much more readable.
This patch finishes all the easy stuf in the core, the remainder is either unobvious
or would result in smaller readability gains. It will be carefully dealt with in
further commits.

Find: /isset\(\s*([^()]+?)\s*\)\s*\?\s*\1\s*:\s*/
Replace with: '\1 ?? '
(Everywhere except includes/PHPVersionCheck.php)
(Then, manually fix some line length and indentation issues)
Then manually reviewed the replacements for cases where confusing
operator precedence would result in incorrect results
(fixing those in I478db046a1cc162c6767003ce45c9b56270f3372).

`$a <=> $b` returns `-1` if `$a` is lesser, `1` if `$b` is lesser,
and `0` if they are equal, which are exactly the values 'sort()'
callbacks are supposed to return.
It also enables the neat idiom `$a[x] <=> $b[x] ?: $a[y] <=> $b[y]`
to sort arrays of objects first by 'x', and by 'y' if they are equal.
* Replace a common pattern like `return $a < $b ? -1 : 1` with the
new operator (and similar patterns with the variables, the numbers
or the comparison inverted). Some of the uses were previously not
correctly handling the variables being equal; this is now
automatically fixed.
* Also replace `return $a - $b`, which is equivalent to `return
$a <=> $b` if both variables are integers but less intuitive.
* (Do not replace `return strcmp( $a, $b )`. It is also equivalent
when both variables are strings, but if any of the variables is not,
'strcmp()' converts it to a string before comparison, which could
give different results than '<=>', so changing this would require
careful review and isn't worth it.)
* Also replace `return $a > $b`, which presumably sort of works most
of the time (returns `1` if `$b` is lesser, and `0` if they are
equal or `$a` is lesser) but is erroneous.
