Fix broken links

* Refactor test into two packages (#1)

* move test and test_core to packages folder

* rename test_core to test_api

* rename packages to pkgs, add dart.js back to repo

* change pubspec to point to test_api version

* move to correct dir in travis.yml

* Remove duplicate utils.dart

- Remove APIs that are no longer used.
- Switch to `TypeMatcher` instead of manual implementation for exception
  matchers.
- Drop `isDart2` since we only run in Dart 2 mode everywhere.

* Allow remote_listener to be closed and sent an event on close.

Clean up a few violations that weren't corrected by dartfmt --fix.
Dartfmt would eventually fix these but a new version of the tool needs
to be published.

- Run `dartfmt --fix`
- Limit to 2.0.0 stable and newer SDK.

Fixes #915

When there is no `const` the expression is parsed as a
`MethodInvocation` instead of an `InstanceCreationExpression`. Update
all the places we were casting to the latter so that it can handle
either case.

Add some additional tests for import prefix cases.

* add precompiled json reporter tests

* fix json reporter to not assume file uris for frames

* update pubspec/changelog

Prepare to publish version 1.3.2

* Add missing return to fix analysis error with 2.1.0-dev.0.0.

* Add a few more missing returns

* Format files

* Use toFilePath() instead of .path on Uri to support Windows

Fixes #918.

- Use `??`, `??=`, and `?.` instead of explicit `== null`.
- Use consistent single quotes

Towards #915

The CFE will already reject this code if it is incorrect, we don't need
to also check for syntax errors.

- Remove the explict checks for `const`
- Remove the explicit checks for using valid constructor names and
  argument types.
- Update test to remove most of the `const` in examples. Retain const
  constructor calls since we can't yet parse the resulting expression if
  it is omitted.
- Remove tests for the removed explicit checks.

Decoding input bytes by doing `.map(utf8.decode)` assumes that input byte chunks are split at encoded code-unit boundaries.
It's safer to use `.transform(utf8.decoder)` which allows encodings to be split accross input chunks.

Also changed `.listen(f).asFuture()` to the equivalent `.forEach(f)`.

* allow serving files outside the precompiled directory, so that symlinks can be supported

* update pubspec/changelog

* change version to 1.3.0

- Update expectation now that dart2js produces different color output.
- Skip tests against a graceful fallback for invalid code that can no
  longer parse.

* support loading .vm.app.dill files in precompiled mode

* add a test for loading from dill files

* update pubspec/changelog for 1.2.0 release

Fixes #889.

Updated test to make new output of Type mismatch errors
Update usage of isInstanceOf to TypeMatcher
