There has been some confusion about whether or not
.flutter-plugins-dependencies should be tracked in version control or
not. Added a comment to both it and .flutter-plugins explaining that
it's generated and shouldn't be.
.flutter-plugins-dependencies is parsed through JSON, and the JSON spec
doesn't support comments. So unfortunately the note is living in an
arbitrary "_info" key instead of an obvious top level comment.
* de-null dartDefines in daemon mode
* remove daemonCommand; pipe through dartDefines into Daemon
* pass dartDefiles in attach; add test for --machine mode
