In the past, the sanitizer would remove unsafe elements, but still
traverse and sanitize (and potentially preserve) their content. This was
problematic in the case of `<style></style>` tags, whose content would
be converted to HTML text nodes.
In order to fix this, the sanitizer's behavior was changed in #25879 to
ignore the content of _all_ unsafe elements. While this fixed the
problem with `<style></style>` tags, it unnecessarily removed the
contents for _any_ unsafe element. This was an unneeded breaking change.
This commit partially restores the old sanitizer behavior (namely
traversing content of unsafe elements), but introduces a list of
elements whose content should not be traversed if the elements
themselves are considered unsafe. Currently, this list contains `style`,
`script` and `template`.
Related to #25879 and #26007.

Currently if an embedded view contains projected nodes, its `rootNodes` array will include `null` instead of the root nodes inside the projection slot. This manifested itself in one of the Material unit tests where we stamp out a template and then move its `rootNodes` into the overlay container.
This PR is related to FW-1087.

For efficiency reasons we often put several different data types (`RNode`, `LView`, `LContainer`,
`StylingContext`) in same location in `LView`. This is because we don't want to pre-allocate
space
for it because the storage is sparse. This file contains utilities for dealing with such data
types.
How do we know what is stored at a given location in `LView`.
- `Array.isArray(value) === false` => `RNode` (The normal storage value)
- `Array.isArray(value) === true` => than the `value[0]` represents the wrapped value.
- `typeof value[TYPE] === 'object'` => `LView`
- This happens when we have a component at a given location
- `typeof value[TYPE] === 'number'` => `StylingContext`
- This happens when we have style/class binding at a given location.
- `typeof value[TYPE] === true` => `LContainer`
- This happens when we have `LContainer` binding at a given location.
NOTE: it is assumed that `Array.isArray` and `typeof` operations are very efficient.

`LView`, `LContainer`, `StylingContext` are all arrays which wrap either
an `HTMLElement`, `LView`, `LContainer`, `StylingContext`. It is often
necessary to retrieve the correct type of element from the location
which means that we often have to wrap the arrays. Logically it makes
more sense if the thing which we are wrapping is at `0` location. Also
it may be more performant since data is more local which may result in
more L2 cache hits in CPU.
PR Close#28947
This change contains conditionally attached classes which provide human readable (debug) level
information for `LView`, `LContainer` and other internal data structures. These data structures
are stored internally as array which makes it very difficult during debugging to reason about the
current state of the system.
Patching the array with extra property does change the array's hidden class' but it does not
change the cost of access, therefore this patching should not have significant if any impact in
`ngDevMode` mode. (see: https://jsperf.com/array-vs-monkey-patch-array)
So instead of seeing:
```
Array(30) [Object, 659, null, …]
```
```
LViewDebug {
views: [...],
flags: {attached: true, ...}
nodes: [
{html: '<div id="123">', ..., nodes: [
{html: '<span>', ..., nodes: null}
]}
]
}
```

If an interface is not exported publicly from its package, then the doc-gen
does not see it, and so cannot include it in the generated documentation.
This was the case for a number of `...Decorator` interfaces, such as
`PipeDecorator` and `InputDecorator.
This commit adds these interfaces to the public export to fix this problem.

- TView no longer stores childIndex
- LView now as CHILD_HEAD and CHILD_TAIL
TView used to store the head of the list, therefor all LViews had to have the same head, which is incorrect.

In certain configurations (such as the g3 repository) which have lots of
small compilation units as well as strict dependency checking on generated
code, ngtsc's default strategy of directly importing directives/pipes into
components will not work. To handle these cases, an additional mode is
introduced, and is enabled when using the FileToModuleHost provided by such
compilation environments.
In this mode, when ngtsc encounters an NgModule which re-exports another
from a different file, it will re-export all the directives it contains at
the ES2015 level. The exports will have a predictable name based on the
FileToModuleHost. For example, if the host says that a directive Foo is
from the 'root/external/foo' module, ngtsc will add:
```
export {Foo as ɵng$root$external$foo$$Foo} from 'root/external/foo';
```
Consumers of the re-exported directive will then import it via this path
instead of directly from root/external/foo, preserving strict dependency
semantics.

This commit splits apart selector_scope.ts in ngtsc and extracts the logic
into two separate classes, the LocalModuleScopeRegistry and the
DtsModuleScopeResolver. The logic is cleaned up significantly and new tests
are added to verify behavior.
LocalModuleScopeRegistry implements the NgModule semantics for compilation
scopes, and handles NgModules declared in the current compilation unit.
DtsModuleScopeResolver implements simpler logic for export scopes and
handles NgModules declared in .d.ts files.
This is done in preparation for the addition of re-export logic to solve
StrictDeps issues.

Initially when we introduced the cronjob for Saucelabs,
we specified that the tests should run every 4h. Since the
caretaker needs more recent results when merging PRs
or before creating a release, we should run the saucelabs
tests every hour. This still ensures that PRs are not
affected by Saucelabs flakiness or incidents, and
the caretaker can also react better to real browser
failures (and isn't blocked on a 4h time frame)
