Implement a few chunks of new mirror functionality. Many changes, notably:
- Added currentIsolateMirror() to provide non-async access to the
local isolate mirror.
- Added mirrorOf(o) to provide access to local instance mirrors.
- Fleshed out InstanceMirror, InterfaceMirror, and LibraryMirror to
various degrees.
- Added the MirroredError hierarchy, which lets the user handle Dart
errors of various sorts from invocation, etc.
- Introduce lazy resolvers for interface mirrors and library mirrors.
These allow us to build the self-referential library/interface
hierarchy without going mad.
- Added better toStrings all around.
- Extended the isolate_mirror_local_test to cover new functionality.
Other changes that were required or seemed prudent:
- Exposed the error hierarchy to the embedder. They need to be able
to distinguish different error types in some situations. Improved
the documetation around error handles and error propagation.
- Added new functions to the dart embedding api as required. Added
tests for all new dart api functions.

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.
