It's an error to declare a variable twice on a specific template:
```html
<div *ngFor="let i of items; let i = index">

This commit introduces a template type-checking error which helps to detect
and diagnose this problem.

Switches our tslint setup to the standard `tslint.json` linter excludes.
The set of files that need to be linted is specified through a Yarn script.
For IDEs, open files are linted with the closest tslint configuration, if the
tslint IDE extension is set up, and the source file is not excluded.
We cannot use the language service plugin for tslint as we have multiple nested
tsconfig files, and we don't want to add the plugin to each tsconfig. We
could reduce that bloat by just extending from a top-level tsconfig that
defines the language service plugin, but unfortunately the tslint plugin does
not allow the use of tslint configs which are not part of the tsconfig project.
This is problematic since the tslint configuration is at the project root, and we
don't want to copy tslint configurations next to each tsconfig file.
Additionally, linting of `d.ts` files has been re-enabled. This has been
disabled in the past and a TODO has been left. This commit fixes the
lint issues and re-enables linting.

Since it only curries another function, the call is entirely unnecessary.

When the `NgIf` directive is used in a template, its context variables
can be used to capture the bound value. This is typically used together
with a pipe or function call, where the resulting value is captured in a
context variable. There's two syntax forms available:
1. Binding to `NgIfContext.ngIf` using the `as` syntax:
```html
<span *ngIf="(user$ | async) as user">{{user.name}}</span>
```
2. Binding to `NgIfContext.$implicit` using the `let` syntax:
```html
<span *ngIf="user$ | async; let user">{{user.name}}</span>
```
Because of the semantics of `ngIf`, it is known that the captured
context variable is non-nullable, however the template type checker
would not consider them as such and still report errors when
`strictNullTypes` is enabled.
This commit updates `NgIf`'s context guard to make the types of the
context variables non-nullable, avoiding the issue.

In the past we had connecitivity issues on Saucelabs. Browsers on
mobile devices were not able to properly resolve the `localhost`
hostname through the tunnel. This is because the device resolves
`localhost` or `127.0.0.1` to the actual Saucelabs device, while it
should resolve to the tunnel host machine (in our case the CircleCI VM).
In the past, we simply disabled the failing devices and re-enabled the
devices later. At this point, the Saucelabs team claimed that the
connecitivy/proxy issues were fixed.
Saucelabs seems to have a process for VMs which ensures that requests to
`localhost` / `127.0.0.1` are properly resolved through the tunnel. This
process is not very reliable and can cause tests to fail. Related issues have been
observed/mentioned in the Saucelabs support docs. e.g.
https://support.saucelabs.com/hc/en-us/articles/115002212447-Unable-to-Reach-Application-on-localhost-for-Tests-Run-on-Safari-8-and-9-and-Edgehttps://support.saucelabs.com/hc/en-us/articles/225106887-Safari-and-Internet-Explorer-Won-t-Load-Website-When-Using-Sauce-Connect-on-Localhost
In order to ensure that requests are always resolved through the tunnel,
we add our own domain alias in the CircleCI's hosts file, and enforce that
it is always resolved through the tunnel (using the `--tunnel-domains` SC flag).
Saucelabs devices by default will never resolve this domain/hostname to the
actual local Saucelabs device.

Previously we would write to class/style as strings `element.className` and `element.style.cssText`. Turns out that approach is good for initial render but not good for updates. Updates using this approach are problematic because we have to check to see if there was an out of bound write to style and than perform reconciliation. This also requires the browser to bring up CSS parser which is expensive.
Another problem with old approach is that we had to queue the DOM writes and flush them twice. Once on element advance instruction and once in `hostBindings`. The double flushing is expensive but it also means that a directive can observe that styles are not yet written (they are written after directive executes.)
The new approach uses `element.classList.add/remove` and `element.style.setProperty/removeProperty` API for updates only (it continues to use `element.className` and `element.style.cssText` for initial render as it is cheaper.) The other change is that the styling changes are applied immediately (no queueing). This means that it is the instruction which computes priority. In some circumstances it may result in intermediate writes which are than overwritten with new value. (This should be rare)
Overall this change deletes most of the previous code and replaces it with new simplified implement. The simplification results in code savings.
PR Close#34804
NOTE: This change must be reverted with previous deletes so that it code remains in build-able state.
This change deletes old styling code and replaces it with a simplified styling algorithm.
The mental model for the new algorithm is:
- Create a linked list of styling bindings in the order of priority. All styling bindings ere executed in compiled order and than a linked list of bindings is created in priority order.
- Flush the style bindings at the end of `advance()` instruction. This implies that there are two flush events. One at the end of template `advance` instruction in the template. Second one at the end of `hostBindings` `advance` instruction when processing host bindings (if any).
- Each binding instructions effectively updates the string to represent the string at that location. Because most of the bindings are additive, this is a cheap strategy in most cases. In rare cases the strategy requires removing tokens from the styling up to this point. (We expect that to be rare case)S Because, the bindings are presorted in the order of priority, it is safe to resume the processing of the concatenated string from the last change binding.

This change moves information from instructions to declarative position:
- `ɵɵallocHostVars(vars)` => `DirectiveDef.hostVars`
- `ɵɵelementHostAttrs(attrs)` => `DirectiveDef.hostAttrs`
When merging directives it is necessary to know about `hostVars` and `hostAttrs`. Before this change the information was stored in the `hostBindings` function. This was problematic, because in order to get to the information the `hostBindings` would have to be executed. In order for `hostBindings` to be executed the directives would have to be instantiated. This means that the directive instantiation would happen before we had knowledge about the `hostAttrs` and as a result the directive could observe in the constructor that not all of the `hostAttrs` have been applied. This further complicates the runtime as we have to apply `hostAttrs` in parts over many invocations.
`ɵɵallocHostVars` was unnecessarily complicated because it would have to update the `LView` (and Blueprint) while existing directives are already executing. By moving it out of `hostBindings` function we can access it statically and we can create correct `LView` (and Blueprint) in a single pass.
This change only changes how the instructions are generated, but does not change the runtime much. (We cheat by emulating the old behavior by calling `ɵɵallocHostVars` and `ɵɵelementHostAttrs`) Subsequent change will refactor the runtime to take advantage of the static information.

With 5cecd97493 we intended to expand
the input type of the `disabled` input of the `NgModel` directive.
Read more about the reason for this in the actual commit message.
Currently though, the acceptance coercion member does not have any
effect. This is because the acceptance member needs to refer to the
actual input property name, and not to the public input name.
`disabled` corresponds to the `isDisabled` property.
PR Close#34502
NgModel internally coerces any arbitrary value that will assigned
to the `disabled` `@Input` to a boolean. This has been done to
support the common case where developers set the disabled attribute
without a value. For example:
```html
<input type="checkbox" [(ngModel)]="value" disabled>
```
This worked in View Engine without any errors because inputs were
not strictly checked. In Ivy though, developers can opt-in into
strict template type checking where the attribute would be flagged.
This is because the `NgModel#isDisabled` property type-wise only
accepts a `boolean`. To ensure that the common pattern described
above can still be used, and to reflect the actual runtime behavior,
we should add an acceptance member that makes it work without type
checking errors.
Using a coercion member means that this is not a breaking change.

Occasionally a factory function needs to be generated for an "invalid"
constructor (one with parameters types which aren't injectable). Typically
this happens in JIT mode where understanding of parameters cannot be done in
the same "up-front" way that the AOT compiler can.
This commit changes the JIT compiler to generate a new `invalidFactoryDep`
call for each invalid parameter. This instruction will error at runtime if
called, indicating both the index of the invalid parameter as well as (via
the stack trace) the factory function which was generated for the type being
constructed.

Originally, QueryList implemented Iterable and provided a Symbol.iterator
on its prototype. This caused issues with tree-shaking, so QueryList was
refactored and the Symbol.iterator added in its constructor instead. As
part of this change, QueryList no longer implemented Iterable directly.
Unfortunately, this meant that QueryList was no longer assignable to
Iterable or, consequently, NgIterable. NgIterable is used for NgFor's input,
so this meant that QueryList was not usable (in a type sense) for NgFor
iteration. View Engine's template type checking would not catch this, but
Ivy's did.
As a fix, this commit adds the declaration (but not the implementation) of
the Symbol.iterator function back to QueryList. This has no runtime effect,
so it doesn't affect tree-shaking of QueryList, but it ensures that
QueryList is assignable to NgIterable and thus usable with NgFor.
