It makes sense for SlotDiffRenderer to localize the diffs that it
returns.
DifferenceEngine can't conveniently use this right now since it stores
all slot diffs concatenated together in a cache entry. It can't break
the string apart again to call the right SlotDiffRenderer on each
slot diff. So it assumes there must be a text diff in there somewhere
and calls TextDiffer over the whole thing.
EntitySchema does not have this problem and can benefit from this
method.

getTablePrefix() is used to show the inline legend and inline switcher.
It is not yet part of a released stable interface.
Theoretically there may be multiple text slots on a page, and we don't
want multiple inline legends. There was already a fragment assembly
system, for the benefit of hook handlers, so move that up to the page
level, so that it can also deduplicate prefix fragments coming from
each slot.
Add tests.

Add a switch that allows toggling between inline and two-column format
when Wikidiff2 is installed.
Inline toggle should also support no-JS toggling
The legend should toggle when switching from table to inline after the
first load.
Introduced a temporary feature flag to show this inline toggle so that
we can merge and easily continue the improvements. It will be removed
when ready for production.

When the old and new content object for a slot cannot be compared,
show an error message for that slot only, instead of throwing an
exception.

When the old and new revisions have identical content in a given slot,
do not include the relevant SlotDiffRenderer in the return value of
DifferenceEngine::getSlotDiffRenderers(), so that the relevant table
prefixes and modules will be omitted.
Also:
* In TextSlotDiffRenderer::getTextDiff(), return an empty string when
the inputs are equal, instead of invoking the diff engine. Previously,
the inline format would produce a <tr> element in this case, causing
the diff-empty message to be omitted.
* Clarify the doc comment up the stack, indicating SlotDiffRenderer may
return zero <tr> tags, it doesn't have to be one or more.
* Fix the documented return type of getSlotContents() so that @var is
not needed in the caller.
* Don't convert the return value of SlotDiffRenderer::getDiff() to
boolean. It's always a string so compare it to the empty string.
Note that the cache key for inline empty diffs will change, because
TextSlotDiffRenderer::getExtraCacheKeys() is not called anymore for
empty diffs.

Add a legend at the top of the inline diff display, showing the
meanings of the colours of the inserted and deleted highlighting.
Also add the same text as tooltips on the highlighted elements.
The legend is added as part of a new area above the diff table
that can be modified via a new TextSlotDiffRendererTablePrefix
hook, so that extensions can add other buttons etc. there as
required.
This is a follow-up to the previous attempt, which added the
legend in DifferenceEngine::showDiff() and was called from
too many places. This patch moves it to be called in
DifferenceEngine::showDiffPage().

UnknownContentHandler can be configued to handle models that
belong to extensions that have been undeployed:
$wgContentHandlers['xyzzy'] = 'UnknownContentHandler';
This way, no errors will be thrown when trying to access
pages with the unsupported model. Instead, an error message is
shown, and editing is prevented.
This patch also improves handling of non-editable content in
EditPage and in DifferenceEngine.

I cannot find any trace of the getSlotDiffRendererClass method mentioned
in the old comment – even patch set 1 of I2f8a9dbebd, which introduced
the whole SlotDiffRenderer class, already had getSlotDiffRenderer and
getSlotDiffRendererInternal instead of getSlotDiffRendererClass in
ContentHandler.

Move logic for rendering a diff between two content objects out of
DifferenceEngine, into a new SlotDiffRenderer class. Make
DifferenceEngine use multiple SlotDiffRenderers, one per slot.
This separates the class tree for changing high-level diff properties
such as the header or the revision selection method (same as before:
subclass DifferenceEngine and override ContentHandler::getDiffEngineClass
or implement GetDifferenceEngine) and the one for changing the actual
diff rendering for a given content type (subclass SlotDiffRenderer and
override ContentHandler::getSlotDiffRenderer or implement
GetSlotDiffRenderer). To keep B/C, when SlotDiffRenderer is not overridden
for a given content type but DifferenceEngine is, that DifferenceEngine
will be used instead.
The weak point of the scheme is overriding the DifferenceEngine methods
passing control to the SlotDiffRenderers (the ones calling
getDifferenceEngines), without calling the parent. These are:
showDiffStyle, getDiffBody, getDiffBodyCacheKeyParams. Extensions doing
that will probably break in unpredictable ways (most likely, only
showing the main slot diff). Nothing in gerrit does it, at least.
A new GetSlotDiffRenderer hook is added to modify rendering for content
models not owned by the extension, much like how GetDifferenceEngine
works.
Also deprecates public access to mNewRev/mOldRev and creates public
getters instead. DifferenceEngine never supported external changes to
those properties, this just acknowledges it.
