The `ng-dev release publish` command needs to check whether a commit
closed a pull request. This is implemented via checking the commit
message for specific closing keywords referencing the pull request
number.
The regex used previously failed to correctly ensure that the specified
pull request was referenced. For example, it would allow `#12345` to
also match for `#1234`.
This commit fixes the regex.

Previously the `node.name` property was only checked to ensure it was
defined. But that meant that it was a `ts.BindingName`, which also includes
`ts.BindingPattern`, which we do not support. But these helper methods were
forcefully casting the value to `ts.Identifier.
Now we also check that the `node.name` is actually an `ts.Identifier`.

Previously directive "queries" that relied upon a namespaced type
```ts
queries: {
'mcontent': new core.ContentChild('test2'),
}
```
caused an error to be thrown. This is now supported.

Previously, any declarations that were defined "inline" were not
recognised by the `UmdReflectionHost`.
For example, the following syntax was completely unrecognized:
```ts
var Foo_1;
exports.Foo = Foo_1 = (function() {
function Foo() {}
return Foo;
})();
exports.Foo = Foo_1 = __decorate(SomeDecorator, Foo);
```
Such inline classes were ignored and not processed by ngcc.
This lack of processing led to failures in Ivy applications that relied
on UMD formats of libraries such as `syncfusion/ej2-angular-ui-components`.
Now all known inline UMD exports are recognized and processed accordingly.

Previously these tests were checking multiple specific expression
types. The new helper function is more general and will also support
`PropertyAccessExpression` nodes for `InlineDeclaration` types.
PR Close#38959
Previously the `ConcreteDeclaration` and `InlineDeclaration` had
different properties for the underlying node type. And the `InlineDeclaration`
did not store a value that represented its declaration.
It turns out that a natural declaration node for an inline type is the
expression. For example in UMD/CommonJS this would be the `exports.<name>`
property access node.
So this expression is now used for the `node` of `InlineDeclaration` types
and the `expression` property is dropped.
To support this the codebase has been refactored to use a new `DeclarationNode`
type which is a union of `ts.Declaration|ts.Expression` instead of `ts.Declaration`
throughout.

This makes these tests more resilient to changes in the test code
structure. For example switching from
```
var SomeClass = <implementation>;
exports.SomeClass = SomeClass;
```
to
```
exports.SomeClass = <implementation>;
```

Previously `getDeclaration()` would only return the first node that matched
the name passed in and then assert the predicate on this single node.
It also only considered a subset of possible declaration types that we might
care about.
Now the function will parse the whole tree collecting an array of all the
nodes that match the name. It then filters this array based on the predicate
and only errors if the filtered array is empty.
This makes this function much more resilient to more esoteric code formats
such as UMD.

The new function does not try to restrict the kind of AST node that it
finds, leaving that to the caller. This will make it more resuable in the
UMD reflection host.

Sometimes UMD exports appear in the following form:
```
exports.MyClass = alias1 = alias2 = <<declaration>>
```
Previously the declaration of the export would have been captured
as `alias1 = alias2 = <<declaration>>`, which the `PartialInterpreter`
would have failed on, since it cannot handle assignments.
Now we skip over these aliases capturing only the `<<declaration>>`
expression.

UMD files export values by assigning them to an `exports` variable.
When evaluating expressions ngcc was failing to cope with expressions
like `exports.MyComponent`.
This commit fixes the `UmdReflectionHost.getDeclarationOfIdentifier()`
method to map the `exports` variable to the current source file.

This clarifies that this is specifically about statements of the form

There is no need to check that the `ref.node` is of any particular type
because immediately after this check the entry is tested to see if it passes
`isClassDeclarationReference()`.
The only difference is that the error that is reported is slightly different
in the case that it is a `ref` but not one of the TS node types.
Previously:
```
`Value at position ${idx} in the NgModule.${arrayName} of ${
className} is not a reference`
```
now
```
`Value at position ${idx} in the NgModule.${arrayName} of ${
className} is not a class`
```
Arguably the previous message was wrong, since this entry IS a reference
but is not a class.

When working on the docs, it is helpful to run a local instance of the
angular.io app and run scripts that watch both the docs contents and the
app build artifacts to automatically update the running instance on
changes. Typically, this is achieved via the `start` and `docs-watch`
npm scripts. As a convenience, one can run the `serve-and-sync` script,
which runs both in one terminal.
Previously, it was not possible to pass arguments to `ng nerve` (which
is what the `start` script runs under the hood) when running it via
`serve-and-sync`.
This commit adds support for passing any arguments passed to
`serve-and-sync` through to the `start` script. This can be useful for
things like specifying a custom host or port.

A common review request is updating the commit message of a commit.
Since this is something that is not straight forward for inexperienced
contributors, it is useful to be able to point a contributor to some
docs outlining the process.
This commit adds such a section in `CONTRIBUTING.md` (as discussed in
https://github.com/angular/angular/pull/39110#discussion_r499935502).

Although in SSR we patch the global prototypes with DOM globals
like Element and Node, this patch does not occur before the

At a high level, the current shadow DOM shim logic works by escaping the content of a CSS rule
(e.g. `div {color: red;}` becomes `div {%BLOCK%}`), using a regex to parse out things like the
selector and the rule body, and then re-adding the content after the selector has been modified.
The problem is that the regex has to be very broad in order capture all of the different use cases,
which can cause it to match strings suffixed with a semi-colon in some places where it shouldn't,
like this URL from Google Fonts `https://fonts.googleapis.com/css2?family=Roboto:wght@400;500&display=swap`.
Most of the time this is fine, because the logic that escapes the rule content to `%BLOCK%` will
have converted it to something that won't be matched by the regex. However, it breaks down for rules
like `@import` which don't have a body, but can still have quoted content with characters that can
match the regex.
These changes resolve the issue by making a second pass over the escaped string and replacing all
of the remaining quoted content with `%QUOTED%` before parsing it with the regex. Once everything
has been processed, we make a final pass where we restore the quoted content.
In a previous iteration of this PR, I went with a shorter approach which narrowed down the
regex so that it doesn't capture rules without a body. It fixed the issue, but it also ended
up breaking some of the more contrived unit test cases. I decided not to pursue it further, because
we would've ended up with a very long and brittle regex that likely would've broken in even weirder
ways.

instructions in dev-infra/browsers/README.md.
With Chrome 86 about to be released as stable, the current local version
