This makes these checks useful in situations where you don't want to spend
an extra statement, like `=>` bodies or initializer lists (including
forwarding generative constructors).

Support Unix domain sockets communication on Linux, MacOS and Android.
Changes:
1. Add a field for InternetAddressType named unix.
2. Constructor of InternetAddress gains one more optional field: type. InternetAddress(String address, {InternetAddressType type});
3. Add another constructor to InternetAddress which taks raw address/path for ip/unix addresses as an argument. InternetAddress.fromRawAddress(Uint8List rawAddress, {InternetAddressType type});
The operation for unix domain sockets communication is basically the same as normal sockets except an InternetAddress with type unix should be passed.

This is a breaking change. https://github.com/dart-lang/sdk/issues/40709
This change makes the HeaderValue parsing more strict in two invalid
edge cases, supports parameters with null values as a feature, and fixes
toString() so it always produces tokens or quoted-strings valid per RFC
7230 3.2.6.
The empty parameter value without double quotes (which is not allowed by
the standards) is now parsed as the empty string rather than null. E.g.
HeaderValue.parse("v;a=").parameters now gives {"a": ""} rather than
{"a": null}.
Invalid inputs with unbalanced double quotes are now rejected. E.g.
HeaderValue.parse('v;a="b').parameters will now throw a HttpException
instead of giving {"a": "b"}.
The HeaderValue.toString() method now supports parameters with null
values by omitting the value. E.g.:
HeaderValue("v", {"a": null, "b": "c"}).toString()
now gives
v; a; b=c
This behavior can be used to implement some features in the Accept and
Sec-WebSocket-Extensions headers.
Likewise the empty value and values using characters outside of RFC 7230
3.2.6 tokens are now correctly implemented by double quoting such values
with escape sequences. E.g.:
HeaderValue("v",
{"a": "A", "b": "(B)", "c": "", "d": "ø", "e": "\\\""}).toString()
now gives
v;a=A;b="(B)";c="";d="ø";e="\\\""
The NNBD migration required making subtle changes to some dart:io

Technically almost no user of ddc should be able to reach this compile-time error if they are using webdev (it appears a couple users do invoke it directly, though). Project sass demonstrated that users of dart2js can notice this breaking change.
Given that we are bundling many breaking changes for null-safety on the next release, it seems like making imports to dart:mirrors a compile-time error is not strictly necessary at this time.
One idea is to change this to a compile-time error in our tools when users opt-in their libraries or when they enable strong null-safety mode.

The dummy object returned if FileStat.stat() and FileStat.statSync()
fail now contains Unix epoch timestamps instead of null for the
accessed, changed, and modified getters.
These timestamps are always non-null if the API succeeds and the
timestamps are meaningless when the API fails and returns the
FileSystemEntityType.notFound type. This change makes the timestamps
always non-null, which avoids all legitimate accesses needing a needless
null check when Dart becomes null safe. This change is consistent with
the mode and size getters that are initialized to non-null dummy values
when the API fail.

- Add a shared error message for a non-external constructor.
- Check for non-external non-factory constructors constructors in the JS interop
checks.
- Remove commented out code in Dart2JS that used to handle this check.
- Clean up skipped tests due to the missing static error. The status in
`legacy_status_dart2js.csv` has no behavior impact but is removed for
completeness.
- Add `external` to a few test cases.
- Remove unused dart2js error message.
- Add `annotating` to hardcoded spelling list.
- Ignore missing example for web specific error message.
- Switch some dart2js error expectations to GENERIC since the message is no
longer defined with other dart2js errors.
Non-external synthetic constructors are ignored for now. An upcoming change will
automatically convert these to external.

The Process class will now throw a StateError if the process is detached
upon accessing the exitCode getter. It now also throws when not
connected to the child process's stdio upon accessing the stdin, stdout,
and stderr getters. Previously these getters would all return null.
The getters in question are meaningless for detached processes and there
is no reason to use them in that case. To provide a better experience
when Dart becomes null-safe, these getters are changed to throw and
never return null, which avoids all legitimate uses of the getters from
needing a null check that will never fail.

The new constructor creates a view of a (sub range) of the elements of another TypedData object.
It works for both typed lists and ByteData.
The advantage over the .view constructors is that it handles other views properly, including their
offsetInBytes in the start computation, which it is easy to forget to do when you call
SomethingList.view(other.buffer)
directly, and that constructor cannot compensate for the information because it only existed on the object
that the buffer was extracted from, not on the buffer itself.

This change:
* adds the `--use-old-rti` flag to revert to the old behavior
* enables the new behavior by default
* changes the -rti- builders to run the old rti instead of the new rti
* documents the change in CHANGELOG.md
I've kept around the logic as `useNewRti` to avoid swapping all the conditions
in the compiler.

Fixes#39074
DDC emits Dart code that can usually be called with the same semantics
as JS there is no guarantee that a function passed to JS and then
invoked successfully was wrapped with `allowInterop`. The wrapping is
always required in Dart2JS. To make DDC more strict, add interceptors
that check for the usage of `allowInterop`.
Whenever a JS interop function or setter is passed an argument which is
statically typed as a Function, but not wrapped with `allowInterop` at
the call site, wrap it with `assertInterop` which will check the
argument at call time and fail with a clear error if it was not wrapped.
Whenever a JS interop function is torn off, either at the top level or
from an instance, wrap it with a function that will also inject these
checks at runtime.
There are still holes where we can't catch the mistake:
- An argument which is statically dynamic and a Function at runtime
won't be caught.
- A Function which is stored in a collection won't be caught.
- A JS interop definition where a getter returns a Function which takes
a Function as an argument is not checked.
- A dynamic call through to javascript is not checked.
Changes:
- Refactor `_isJsLibrary` and add `isJsMember`, and `isAllowInterop`
utilities to determine what needs wrapping.
- Update `assertInterop` to give a more clear error when it fails, and
to ignore non function arguments.
- Add `tearoffInterop` to wrap a function an ensure that any function
typed arguments are wrapped.
- Inject `assertInterop` around Function arguments passed to JS methods.
- Inject `assertInterop` around Function arguments passed to static or
instance JS setters.
- Inject a runtime wrapper around static or instance Function tearoffs.
- Add a test covering all flavors of checks that are supported.
- Change the interop expando to an `Expando<dynamic>` in the NNBD SDK to work
around a stricter type check. https://github.com/dart-lang/sdk/issues/39971
Potential improvements:
If the `tearoffInterop` turns out to be too heavy, we could loosen it so
that we only wrap methods if any of their argument types are statically
declared to be a Function.
