replace it with the beginnings of a local (same isolate) IsolateMirror implementation. Removed old mirror tests and added two new mirror tests. Even though mirrors.cc is part of the vm, I chose to implement most of it using the dart embedding interface instead of our internal interfaces because the embedding interface was more convenient. mirrors.cc is basically all new in this CL -- don't pay any attention to diffs for that file. Added dart embedding functions required for the functionality in this CL: Dart_DebugName, Dart_GetNativeInstanceFieldCount, Dart_RootLibrary, Dart_RegisteredLibraryUrls, and Dart_LibraryName. Extended or modified some existing dart api functions, primarily to make them propagate error handles properly. Added tests for new dart embedding api functionality. Added the ability to determine if a port is local to the current isolate. Extended NotImplementedException to accept an optional string argument. I wanted to give more descriptive error messages.
