The getTransition helper function ensures that urlAfterRedirects is assigned for when
the router does not process the previous or current URL. In this case, we would set
the browserUrlTree to be the urlAfterRedirects, which was initialized to be the browserUrlTree.
This is a no-op, so there's no need for the getTransition function at all.

These token interfaces will make it easier to reason about tokens in the
parser and in specs.
Previously, it was never clear what items could appear in the `parts`
array of a token given a particular `TokenType`. Now, each token interface
declares a labelled tuple for the parts, which helps to document the token
better.

Previously, the way templates were tokenized meant that we lost information
about the location of interpolations if the template contained encoded HTML
entities. This meant that the mapping back to the source interpolated strings
could be offset incorrectly.
Also, the source-span assigned to an i18n message did not include leading
whitespace. This confused the output source-mappings so that the first text
nodes of the message stopped at the first non-whitespace character.
This commit makes use of the previous refactorings, where more fine grain
information was provided in text tokens, to enable the parser to identify
the location of the interpolations in the original source more accurately.
Fixes#41034
PR Close#43132
The tests were checking that the source-span of parsed HTML nodes were
accurate, but they were not checking the span when it includes the
"leading trivia", which are given by the `fullStart` rather than `start`
location.

When it was tokenized, text content is split into parts that can include
interpolations and encoded entities tokens.
To make this information available to downstream processing, this commit
adds these tokens to the `Text` AST nodes, with suitable processing.

The lexer now splits encoded entity tokens out from text and attribute value tokens.
Previously encoded entities would be decoded and the decoded value would be
included as part of the text token of the surrounding text. Now the entities
have their own tokens. There are two scenarios: text and attribute values.
Previously the contents of `<div>Hello & goodbye</div>` would be a single
TEXT token. Now it will be three tokens:
```
TEXT: "Hello "
ENCODED_ENTITY: "&", "&"
TEXT: " goodbye"
```
Previously the attribute value in `<div title="Hello & goodbye">` would be
a single text token. Now it will be three tokens:
```
ATTR_VALUE_TEXT: "Hello "
ENCODED_ENTITY: "&", "&"
ATTR_VALUE_TEXT: " goodbye"
```
- ENCODED_ENTITY tokens have two parts: "decoded" and "encoded".
- ENCODED_ENTITY tokens are always preceded and followed by either TEXT tokens
or ATTR_VALUE_TEXT tokens, depending upon the context, even if they represent
an empty string.
The HTML parser has been modified to recombine these tokens to allow this
refactoring to have limited effect in this commit. Further refactorings
to use these new tokens will follow in subsequent commits.

Previously, the regular expression used by the compiler's ShadowDOM CSS
shim to strip comments from CSS text was susceptible to [catastrophic
backtracking][1], which could lead to exponential (O(2^n)) increase in
complexity/execution time. More specifically, this would be triggered if
the processed text contained an unterminated comment with lots of
leading whitespace (i.e. `/*`, followed by lots of whitespace characters
and no closing `*/`).
Although such input is unlikely in real-world scenarios, this commit
improves the regular expression to not be susceptible to this issue.

Previously the `http` example did accessed the npmsearch.com website to demonstrate response caching.
But if this service became unavailable then the example (and its e2e tests) would fail.
This commit changes the example to use the in-memory-web-api for this lookup, which will not be affected by 3rd party outages.
The guide that references this example has been updated to avoid references to the original npm search service.

Note that because `angular.json` is a "boilerplate" file we cannot
just add comments to the one that is actually used in the application.
Instead this commit makes a copy, which is annotated with docregions.
To ensure that this file is not ignored by the example-collector, we had to
update the `.gitignore` to not ignore this file. (This also allows the file to be
easily stored tracked in git).

It is now possible to specify file paths in the `"boilerplate-override"`
property of `example-config.json` files to tell the example boilerplate
system to use the file in the example directory rather than overwriting the
example file with that from the boilerplate directory.

This change makes docplaster markers fit better with the surrounding code
that is being rendered. Instead of:
```
{
"a": 100,
// ...
"b": 200,
// ...
}
```
you can now get
```
{
"a": 100,
// ...
"b": 200,
// ...
}
```

Now JSON files should be commented using
```
// #docregion
```
rather than
```
/* #docregion */
```
There are currently no JSON files with either kind of comments so this change
has no impact yet.
But when we add some examples with such comments, they will also benefit
from `// ... ` style docplasters to join docregion fragments.

No test was added for this case because I can't think of a test case to
write that would work.
This change updates the code for a consistent mental model of setting
the `browserUrlTree`. It's only meant to track the `UrlTree` that the
`UrlHandlingStrategy` is set to extract, not the full `rawUrl`. Notice
that everywhere else, the `browserUrlTree` is set to
`urlAfterRedirects`, which is computed based on the extracted URL, _not_
the `rawUrl`.

PR #43102 broke some use-cases. These tests document expected behavior
and would have prevented #43446 and #43447. Recent changes have already
addressed these issues, but it would still be a good idea to cover these
use-cases in tests as well.
