When the server fails to start up (writing to stderr) the tests currently would just hang waiting for responses to messages. This will just throw the message as an exception, failing the test with a more useful message, for example:
```
00:07 +0 -1: ServerTest | test_exit_afterShutdown [E]
Analysis Server wrote to stderr:
file:///Users/dantup/Dev/Google/dart-sdk/sdk/third_party/pkg/linter/lib/src/analyzer.dart:106:27: Error: The method 'registerDefault' isn't defined for the class 'Registry'.
- 'Registry' is from 'package:analyzer/src/lint/registry.dart' ('file:///Users/dantup/Dev/Google/dart-sdk/sdk/pkg/analyzer/lib/src/lint/registry.dart').
Try correcting the name to the name of an existing method, or defining a method named 'registerDefault'.
Registry.ruleRegistry.registerDefault(lint);

This tests we can spawn the diagnostic server on-demand. The test was previously marked failing because it needed to be a real inrtegration test.

This splits the helper functions out of the abstract base test, which will allow them to be reused in integration tests that have their own transport (real stdio to a process).

This adds a new type of error for when a client request to edit a document
is not valid because the document offsets don't match up. In this instance,
the client/server are out of sync and we shouldn't try to continue as we
may produce edits that ruin the users work. The server checks errors being
sent to the client and if it sees this type of error will switch to a state
that requests all messages, send a logMessage and then shut down after a few
seconds.
The LSP spec has been updated to suggest that clients automatically restart
servers if they quit unexpectedly (though advising not to do it forever in
the case of a crash at startup).

Don't send raw errors in showMessage, send a generic message and put the rest in a log (this is to stop dart exceptions being shown unexpectedly in error popups in the editor).
