There are 2 situations:
1. Either the template name is used in a [[…]] link. In this case
we must provide the namespace. MWTemplateModel.getTitle() does
this. However, it's not a mw.Title object and therefor not really
guaranteed to be a valid title. This is fine. The worst thing
that can happen is that the link points to an error message.
But this should be entirely unreachable anyway.
2. Some messages want to display the name of the template.
Ideally without the namespace. That's what
MWTemplateSpecModel.getLabel() is for. Again this is not
guaranteed to be a valid mw.Title. But it doesn't need to. It's
only used as a label.

It appears like it's currently not possible to reach this code
with an invalid template name like `{{foo}}`. But this is not
guaranteed.
The purpose of this code is to call the TemplateData API. This is
pointless when a title is invalid. We know a page with this name
can't exist. So we skip it.
But that's all this code cares about. It should not crash. Nor
does it need to report this situation.
This is related to the discussion in Ic364e75.

This is what actually happens:
* We call `addParameter()`.
* This triggers an `add` event.
* This calls an `MWTemplateDialog.onAddParameter` event handler.
* This code doesn't check if a parameter already exists (because
it shouldn't). It detroys the page in the content pane on the
right and recreates it from scratch.
The only reason we do this is to focus the input field on the
right. This patch introduces a dedicated event to do this.

This check makes sure the user doesn't loose work when clicking
the back button. I would like to argue that neither of these
values is valuable enough to block the user with a confirmation
dialog:
* Literally nothing is lost when the input is empty.
* The auto-value is only temporarily lost, but will
automatically be restored when the user decides to add the
template back. The input field is pre-filled with this value.
* The default value doesn't need to be manually entered. It will
show up anyway when the parameter is missing.
There is a rare edge-case, but it is not really relevant in this
situation. Some templates allow to override a default value with
the empty string. This will be considered irrelevant by this
code. However, this was already happening before and doesn't
change with this patch.
The only edge-case where this patch makes a difference is if a
parameter is marked as required or suggested, is documented to
have a default value, _and_ the template allows to override it
with an empty string. But this combination is rather crazy, if
not bogus, and not worth considering here, I believe.

This is really only about the methods name, but doesn't change
any behavior.
I realized we work with several different definitions of what
"empty" means. There are at least two significant definitions:
1. When a parameter's value is the empty string or identical
to the default value, the behavior of the template is the same.
It will use the default value just as if the user entered it.
The auto-value is a meaningful value in this scenario and can't
be considered equal to the empty string.
2. The context here is when the user presses the back button.
This will destroy all user input. But an auto-value is not user
input. It will appear again when the user realizes they made a
mistake. Nothing is lost.
Personally, I would not use the word "empty" to describe this
concept. Things like "containsUserProvidedValue",
"isCustomValue", "isMeaningfulValue", … come to mind. These are
all still a big vague. A "user provided" value can be identical
to the default or auto-value. "Custom" how? I went for
"containsValuableData" for now.

Notably:
* Don't require the model in the new sidebar via dependency
injection, but connect the event handlers later. This is
relevant because we currently create the new sidebar in the
wrong spot. Removing the hard dependency allows us to split
the code and utilize initialize() and getSetupProcess()
correctly. This will be done in a following patch.
* The change event now includes the new position. This makes
it very easy to add this missing feature to the new sidebar.
Also:
* Stop triggering change events when nothing changed. These

TransclusionModel, and to all linked
onTransclusionModelChange() handlers.

Reasoning:
* format=json must be the default. Nothing else makes sense in
the context of this code. This should not be a surprise.
* formatversion=2 is only a default when the custom
getContentApi() is used, but not when mw.Api is used. One
might argue that it's safer to always specify formatversion=2.
However, this is not done in other places in this codebase.
It should never be done or always.
* I find it confusing when the action=… is missing. Let's not
rely on this default.

If a known parameter is present using one of it's aliases, then
only the aliased name should be shown to the user. This patch,

This fixes a minor issue in the spec class. In the first step,
parameters from the template are added to the list of known
parameters. Later, aliases are resolved. The original behavior
was that such a parameter moved to the end of the list. This
is rather unexpected.
This dosn't have much of an impact. The pretty much only place
where the parameter order from the spec can be seen is in the
parameter search widget. Still I believe it's worth fixing.

Just store the JSON blob from the TemplateData API as is.
This comes with a bunch of nice consequences:
* Less code.
* Less class properties that don't do anything but copy what's
in the TemplateData blob.
* Easier to understand what's going on. The `this.templateData`
property is now a reference to the *actual* TemplateData
documentation.
* No need to cache the documentedParamOrder. Just do it when
needed.
This also removes an unused feature from the `extend()` method
that didn't made sense anyway. Before it was possible to merge
conflicting documentations. But this is not only unused, it's
impossible to have multiple documentations for the same
template.
The method acts as a straight setter now. The next patch will
rename it accordingly.

While the term "canonical" is not wrong, I find it still
somewhat ambiguous.
1. "Canonical" could mean different things. E.g. is the order
of parameters as they appear in the article's wikitext the
"canonical" one? It's possible to argue like this, esp. if a
template doesn't have TemplateData documentation. In this case
the only order known is the one from the wikitext.
2. "Canonical" sounds like the parameters must be reordered.
But this should never happen. Not having dirty diffs is more
important than having the parameters in a specific order.

Wait, what's going on here? This patch looks like it changes the
behavior of this code. But it doesn't. Here is what happened
before:
* Let's say a template contains 2 parameters, A and B.
* We don't know yet if these names are aliases.
* getParameterNames() returns [ "A", "B" ].
* extend() is called. The TemplateData documentation contains
the parameters "B" and "C". "C" does have an alias "A".
* extend() can't find "C" and adds it to the end, as if it's a
new parameter.
* extend() also iterates the aliases. For each alias it creates
a reference to the specification object. In this case a
reference from "A" to "C" is created.
* But "A" already exists. The position of "A" doesn't change,
but the specification now says it's an alias.
* getParameterNames() skips aliases. It skips "A" and instead
returns the new "C" from the end of the list.
This was the behavior before. It's unchanged, proven by the tests.
Change-Id: I04b8a14fbec7be5a1c4defabf92e94f694c1e638
The idea is to not actually store all these default values, but
fall back to the default only when needed.
Some more details:
* The only remaining property is ….name. The only reason to
have this property is to distinguish between aliases and
primary parameter names. This will be reworked in a later
patch.
* The description falls back to null because this is the
documented fallback, not undefined.
* The default value falls back to "", same as the auto-value.
Why not null you might ask. This is intentional. Both the
auto- and default value are effectively wikitext snippets,
while the example is a label in the VE UI.

This is done for two reasons:
1. It fixes the behavior of two methods in rare edge-case
situations. They aren't documented to return undefined.
2. It reduces the amount of stuff this class stores when it's
nothing but a default value anyway. Note this patch does this
for the template-level properties only. Another patch will do
the same for the parameter-level properties.

This reverts the revert commit d47b95eb4a.
When no `paramOrder` is given, known parameters should appear in the
order returned from the TemplateData API.
Previously, when TemplateData was present but no paramOrder
specified, then the parameters would appear in alphabetical order as
"unknown" parameters. Now they will appear in the order listed in
TemplateData. This is similar to the fully-specified behavior when
paramOrder is present.
This will only affect the Visual Editor template dialog, and has no
