If wikidiff2 is installed, use it for diffing without requiring
$wgExternalDiffEngine to be set to 'wikidiff2'.
Also add some extra sanity-checking by coercing all non-string values to
false and make sure the custom diff executable passes `is_executable()`.

These hooks allow things such as:
* adding CSS(/JS) into the OutputPage when viewing diffs
* adding extra HTML content (such as avatars) into diff views
* hiding the bottom "mark as patrolled" link
* altering the parser output that is used by DifferenceEngine
* and more
Example extension using these hooks is wikiHow's
/extensions/wikihow/hooks/, specifically the file DiffHooks.php (but the
hooks are setup in WikihowHooks.php).
Live example of the DiffHooks stuff in action can be found at wikiHow.com,
for example:
http://www.wikihow.com/index.php?title=Set-Your-Homepage&diff=17112892&oldid=15888129
(user avatars, additional CSS, changes to the old/new revision header
texts/links)

Javascript used to look just for the patrollinks class, which

E.g. if you have $wgExternalDiffEngine = 'wikidiff2' but after
a PHP update you no longer have the module you still shouldn't attempt
to shell out to some nonexistent wikidiff2.

It's been unmaintained for a while and does not support
various languages adequately.
Also, document $wgExternalDiffEngine.

Using IContextSource avoids the use of $wgLang and wfMessage which make
use of global $wgTtle.
Add IContextSource as parameter to ChangeTags::formatSummaryRow to avoid
globals. Define an IContextSource instance in all functions which
reference ChangeTags::formatSummaryRow and pass it in ChangeTags::formatSummaryRow
function call.
Also make the default value of IContextSource $context as null in
parameter, to avoid breaking changes for old callers in extensions.
Document default null value of IContextSource and add a @note to prefer
IContextSource over null value.
Remove trailing whitespace, and make code order according to parameter
order.

Follows-up 9cfb9cb9fb, and b62f0e9156.
Add data-mw="interface" to elements created by the interface
(e.g. not user-generated content) and use this to narrow down
scope of elements eligible for JavaScript binding.
This avoids bugs where e.g. the diff hook triggers on a wiki page about diffs.
This isn't a security issue per-se, but causing odd behaviour.
Also add missing tests for data-ooui filtering (follows-up aa9a52da).

The next revision in the page history isn't necessarily the previous
revision (due to selective undeletions, history merges, etc). This
passes the next revision to HistoryRevisionTools so extensions can check
if needed. Also, it passes the user to this hook and DiffRevisionTools
to avoid use of wgUser or having to retrieve context.

These callers don't need to do purges, but can still perfectly
take advantage of this instance over a plain BagOStuff. Namely:
* Replication and snapshot lag awareness
* Preemptive regeneration
* Easy process cache support
The idea is for there to only be one caching class/factory
to use, instead of having rules for picking which one to use.

Graphite expects name components to be dot-separated, so our habit of using
dashes doesn't really make sense. Change metric names to be more compatible
with Graphite, except the job queue's, since that will require a gdash
dashboard definition migration.

* This is a more specific form of the logic removed in 3c2bc32ae1.
It does not suffer the problem of causing constant master DB
queries due to a bad template reference or such.
* It will use the master if writes from the current thread
are pending or were recently committed. This deals with the
common problem of code that needs to read things it just wrote,
such as diffs on rollback or edit hooks.
* This commit reverts 8624e261f by making the hack obsolete.

In DifferenceEngine we need to show a diff immediately after
an edit happened if someone did a rollback. To make that work
again, try loading a revision from master if we have more than
one database servers and we failed loading the revision from
a slave.

* #top, #mw-content-text and others exist, but all point to the
beginning of the diff, not of the actual page content.
* Pick mw- prefix and technical but familiar related name, in
the hope it's not confusing nor too hard to remember.
* Lowercase letters, similar to #top, #footer, #file etc. were also
considered and discard, inspired to usual names:

Seems stupid omission. Title has one. Why do I need to think how
to determine how to users objects point to the same user. Allows
more expressive code.
Also fixes a bug in multiple places where users "0" and "00" were
considered equal.

Xhprof generates this data now. Custom profiling of various
sub-function units are kept.
Calls to profiler represented about 3% of page execution
time on Special:BlankPage (1.5% in/out); after this change
it's down to about 0.98% of page execution time.

The new Extension:WikEdDiff is a custom inline difference engine.
There is currently no hook to integrate custom difference engines.
This patch adds a new hook called 'GetDifferenceEngine' in
/includes/content/ContentHandler.php in function
'createDifferenceEngine()'.
Passed variables:
$context: IContextSource context to be used for diff
$old: Revision ID to show and diff with
$new: Either a revision ID or one of the strings 'cur', 'prev' or 'next'
$refreshCache: If set, refreshes the diff cache
$unhide: If set, allow viewing deleted revs
&$differenceEngine: output parameter, difference engine object to be used
for diff
If the hook handler returns false, a valid difference engine object is
returned in the passed-by-reference variable $differenceEngine.
If the handler returns true, the default engine is used as fallback.
The specified diff engine class will typically be an extension of the
class DifferenceEngine (includes/diff/DifferenceEngine.php) with
modifications, e.g. of function generateTextDiffBody() and
__construct() (without deprecated parameter $rcid).
Also fixes a missing declaration in DifferenceEngine that is required for
extending this class.

It previously added only the page HTML, which meant that ResourceLoader
modules associated with the page and other metadata was lost. This
affected the new way of doing things in SyntaxHighlight (Idf4ad439).
We still do not show categories, language links and other things
on the pages (although internally they behave just like in wikitext)
Also needs a fix in DifferenceEngine because our code sucks so much.
