We use `package:shelf/shelf_io.dart` to serve the requests,
which in turn uses `package:shelf_proxy/shelf_proxy.dart` as
an inner request handler.
On exception (such as seen in the webdev CI failures) the shelf_io
returns 500 response, which is currently is not causing a retry in
RetryTimeoutClient.
This change adds retries on 500.
Add tests with server returning InternalServerError.

Recent flakes in webdev CI show failures to load dill files
due to broken sockets (most likely caused by connection timeouts).
This change adds retries and timeouts to the asset server file
system to make it tolerant to breaking connections.
- Add RetryTimeoutClient wrapper for HttpClient that performs
retries with delays and connection/response timeouts, based
on the idea in
https://github.com/dart-lang/http/blob/master/lib/retry.dart
- Make AssetFileSystem use the RetryTimeoutClient.
- Add tests for reading multiple files concurrently.
- Add tests for ExpressionCompilerWorker reading assets using
standard, multiroot, and asset file systems.
- Simplify uri that AssetFileSystem uses to query the asset
server, since we no longer need to load package uris.
This will eliminate a step in uri translation in dwds.
- Validated that changes do not break google3 manually.

We are seeing CI flakes in webdev when using expression_compiler_worker
in tests involving expression evaluation, for example, see linux tests
for dwds in the following PR:
https://github.com/dart-lang/webdev/pull/1343
The logs show that HttpFileSystemEntity.exists fails due to a broken
pipe, which we suspect is due to http client closed too early.
This change is an attempt to fix the problem by
- logging exceptions thrown in expression compiler worker
- awaiting for the request to be read before closing http client in
HttpFileSystemEntity.

In some cases, such as file system exceptions, ExpressionCompilerWorker
fails to start but does not close its receiver port, which causes the
consumer to wait indefinitely for responses.
Make ExpressionCompilerWorker communicate the failure to the consumer,
close the receiver port, and exit.
Added tests to verify graceful exit.

The full workflow for an end-to-end test:
1) Perform test/compiler options pre-initialization.
2) Start an instance of Chrome (with 1 tab) and save a persisted debug connection for use in all tests.
3) For each separate Dart program to be tested:
1) Create inside a temp directory the HTML bootstrapper, DDC-compiled JS sources, and auxiliary JS files (dart_library.js or require.js).
2) Initialize a DDC ProgramCompiler/IncrementalCompiler and perform a full compile of the program, saving the compiler's state for subsequent incremental compiles.
3) Enable the debugger and set a URL breakpoint at the program's main JS entrypoint.
4) For each test for this Dart program:
1) Navigate to the HTML bootstrapper, pausing when the target module is loaded (at the breakpoint set above).
2) Set a breakpoint at a JS location translated from a Dart breakpoint ID via source maps.
3) Resume the debugger, pausing at that breakpoint. Remove the breakpoint.
4) Reconstruct the local JS scope, then evaluate the Dart expression.
5) Evaluate the JS expression inline, then compare results with expectations.
5) Disable the debugger to clear its state.
4) Shut down Chrome and clean up any temporary directories.
Other notes:
* Supports bootstrapping/compilation on AMD and DDC module systems only (though expression eval is only supported on AMD)
* Requires that Dart breakpoint IDs be set declaratively (no support for columns)
The test structure/flow is subject to change. While I port existing tests, Dart programs will consist of inline source file strings with simple breakpoints. In the future, we want to allow more complicated Dart programs to be specified (like in the modular test framework) and more complicated expression evaluation test patterns (rather than allowing only a single evaluation per test).

During expression evaluation, we are collecting all variables in
all scopes that contain the current breakpoint line, and adding them
as available in current scope, which makes variables declared below
the current breakpoint line declared but undefined in JavaScript.
There is one exception to this seen so far - a variable
declared on the current breakpoint line might appear as not declared
in JavaScript and cause expression evaluation not to work due to
JS compilation errors.
This change fixes the issue by not collecting variables that are
declared on or after the current breakpoint line, making them undeclared
in dart (which also is correct according to dart scoping rules).

This CL adds stub for each concrete mixed in member into mixin
applications. The body of the stub calls the original member via
a super call.
This addition means that resolution of super access now use the
stub and not the original declaration as the target, which means
that it will be correct even when mixed in members are cloned. For
this reason, dart2js no longer needs to perform its own super
member resolution.
When a super call targets a mixin super stub (after cloning) it
can be optimized away by redirecting the call to the `stubTarget`
of the call. This optimization is performed in dart2js.
Since dart2js now uses the correct super target, its runtime
mixin application needs to avoid overriding members already
declared in the mixin application. These members are the
forwarding super stubs which ensure that correct runtime types
when members with covariant parameters are implemented.
