Previously the start of a character indicated by an escape sequence
was being incorrectly computed by the lexer, which caused tokens
to include the start of the escaped character sequence in the
preceding token. In particular this affected the name extracted
from opening tags if the name was terminated by an escape sequence.
For example, `<t\n>` would have the name `t\` rather than `t`.
This fix refactors the lexer to use a "cursor" object to iterate over
the characters in the template source. There are two cursor implementations,
one expects a simple string, the other expects a string that contains
JavaScript escape sequences that need to be unescaped.

The parts of a token are supposed to be an array of not-null strings,
but we were using `null` for tags that had no prefix. This has been
fixed to use the empty string in such cases, which allows the `null !`
hack to be removed.

Prior to this change, TypeScript stripped out some imports in case we reference a type that can be represented as a value (for ex. classes). This fix ensures that we use correct symbol identifier, which makes TypeScript retain the necessary import statements.

This commit removes code duplication around projectables nodes insertion.
It also simplfy the overall logic by using recursive function calls instead
of hand-unrolled stack (we can always optimise this part if needed).

When web-animations and/or CSS keyframes are used for animations certain
CSS style values (such as `display` and `position`) may be ignored by a
keyframe-based animation. Angular should special-case these styles to
ensure that they get applied as inline styles throughout the duration of
the animation.

Angular supports using <style> and <link> tags inline in component
templates, but previously such tags were not implemented within the ngtsc
compiler. This commit introduces that support.

Prior to this change i18n block bindings were converted to Expressions right away (once we first access them), when in non-i18n cases we processed them differently: the actual conversion happens at instructions generation. Because of this discrepancy, the output for bindings in i18n blocks was generated incorrectly (with invalid indicies in pipeBindN fns and invalid references to non-existent local variables). Now the bindings processing is unified and i18nExp instructions should contain right bind expressions.

This commit introduces support for the windows paths in the new concrete types mechanism that was introduced in this PR https://github.com/angular/angular/pull/28523
Normalized posix paths that start with either a `/` or `C:/` are considered to be an absolute path.
Note: `C:/` is used as a reference, as other drive letters are also supported.

Prior to this change, the logic that outputs i18n consts (like `const MSG_XXX = goog.getMsg(...)`) didn't have a check whether a given const that represent a certain i18n message was already included into the generated output. This commit adds the logic to mark corresponding i18n contexts after translation was generated, to avoid duplicate consts in the output.

The partial evaluator in ngtsc can handle a shorthand property declaration
in the middle evaluation, but fails if evaluation starts at the shorthand
property itself. This is because evaluation starts at the ts.Identifier
of the property (the ts.Expression representing it), not the ts.Declaration
for the property.
The fix for this is to detect in TypeScriptReflectionHost when a ts.Symbol
refers to a shorthand property, and to use the ts.TypeChecker method
getShorthandAssignmentValueSymbol() to resolve the value of the assignment
instead.

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.
PR Close#28947
`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.
