When an `NgModel` is created within a `form`, it receives an `NgControl` based on its `name`, but
the control doesn't get swapped out if the name changes. This can lead to problems if the `NgModel`
is part of an `ngFor`, because the name can change based on its position in the list and a new
control can be defined with the same name, leading us to having multiple directives pointing to
the same control. For example, if we start off with a list like :
```
[0, 1, 2]; -> [NgModel(0), NgModel(1), NgModel(2)]
```
Then we remove the second item:
```
[0, 2]; -> [NgModel(0), NgModel(2)]
```
And finally, if we decide to add an item to the end of the list, we'll already have a control for
index 2, causing the list to look like:
```
[0, 2, 3]; -> [NgModel(0), NgModel(2), NgModel(2)]
```
These changes fix the issue by removing the old control when the `name` of the directive changes.

For two-way-bindings that use the banana-in-a-box syntax, the compiler
synthesizes an event assignment expression from the primary expression.
It is valid for the primary expression to be terminated by the non-null
operator, however naive string substitution is used for the synthesized
expression, such that the `!` would immediately precede the `=` token,
resulting in the valid `!=` operator token. The expression would still
parse correctly but it doesn't implement the proper semantics, resulting
in incorrect runtime behavior.
Changing the expression substitution to force a space between the
primary expression and the assignment avoids this mistake, but it
uncovers a new issue. The grammar does not allow for the LHS of an
assignment to be the non-null operator, so the synthesized expression
would fail to parse. To alleviate this, the synthesized expression is
parsed with a special parser flag to allow for this syntax.

This happens if a user writes `<span i18n>Message</span>`. This is accepted as an internationalized message, but without a description. JSCompiler will throw an error in this situation because descriptions are generally required. Now, the Angular compiler will generate a suppression annotation so JSCompiler allows the syntax. This will ease an internal migration to JSCompiler-based i18n.

This code mimics behavior that Google Analytics has been using to
prevent duplicate navigations. They set up their own `HybridRoutingService`
location sync to avoid duplicate navigations that came from the Angular
router. This would happen because the Angular router would trigger a
navigation, which would then get picked up by the `$locationShim`, which
would trigger a `$locationChangeStart`, which would then be picked up by
the `setUpLocationSync` watcher here, which would again trigger a
navigation in the Angular Router.
All of this can be prevented by checking if the `navigationId` exists on
the history state object. This property is added by the Angular router
during navigations.

The logical filesystem would store a cached result based on the canonical path,
where the cached value contains the physical path that was originally provided.
This meant that other physical paths with an identical canonical path would use
a cached result derived from another physical path.
This inconsistency is not known to result in actual issues but is primarily
being made as a performance improvement, as using the provided physical paths
as cache key avoids the need to canonicalize the path if its result is already
cached.

The generated imports should normally use module specifiers that are valid for
use in production code, where arbitrary relative imports into e.g. node_modules
are not allowed. For template type-checking code it is however acceptable to
use relative imports, as such files are never emitted to JS code. It is
desirable to allow a filesystem relative import as fallback if an import would
otherwise fail to be generated, as doing so allows fewer situations from
needing an inline type constructor.

This commit removes the leftover `Identifiers` class that was used in the
ViewEngine compiler. The remaining usages of the `inlineInterpolate` and
`interpolate` instructions were refactored to make use of an
`InterpolationExpression` output expression to capture the argument list of an
interpolation expression. An attempt was made to refactor this further by
converting to the desired interpolation instruction immediately, but some
downstream consumers are designed in a way where the argument list itself is
needed, e.g. as other arguments need to be prepended/appended.

When `HttpTestingController.verify` is used to verify that there are not open,
unexpected requests it would throw an error with the method and URL of all pending
requests, excluding the query parameters. This is confusing, as e.g. `expectOne`
matches a URL including its query parameters and `expectOne` does include the
query parameters when it reports when no request could be matched.
This commit changes the error that is reported by `verify` to include the query
parameters.

Support for namespace URIs rather than short namespace names was added in
https://github.com/angular/angular/commit/2b9cc8503d48173492c29f5a271b61126104fbdb to
support how Ivy passed around the namespace URI rather than short name at the time.
As a side-effect, this meant that namespace URIs were supported by the
default dom renderer as part of the public API (likely unintentionally).
It did not, however extend the support to other parts of the system (setAttribute, setAttribute,
and the ServerRenderer). In the future we should decide what exactly the
semantics for dealing with namespaces should be and make it consistent.
