Highlights:
- Implement FunctionClassMirror, used to reflect on the class of
function objects.
- Implement TypeVariableMirror, used to reflect on type variables.
- Implement TypedefMirror, used to reflect on typedefs.
- Implement returnType for MethodMirror
- Implement type for VariableMirror/ParameterMirror
- Added supporting functions to the dart embedding api:
- Dart_ClassIsTypedef
- Dart_ClassGetTypedefReferent
- Dart_ClassIsFunctionClass
- Dart_ClassGetFunctionClassSignature
- Dart_FunctionReturnType
- Dart_FunctionParameterType
- Dart_VariableType
- Dart_GetTypeVariableNames
- Dart_LookupTypeVariable
- Dart_IsTypeVariable
- Dart_TypeVariableOwner
- Dart_TypeVariableUpperBound
Other stuff:
- Fixed bug in Function::NumberOfImplicitParameters for signature
functions.
- Chnaged the default upper bound for type variables to Object from
Dynamic. Discussed this with Gilad and Regis.
- Fixed some smaller problems in mirrors_impl.dart.

This is a request for comments. Do we want to expose library
prefixes like this? Is there a way to import with a prefix already
and lookup members?
The reason why I would like to do this is so that I can import the
user-supplied builtins library under a prefix. This will be a useful
first step to move the print function to corelib while preserving
the ability to patch in a print implementation via the builtins
library.

The native ports use the snapshot reader to create the dart objects. Added support for reading external arrays from snapshots but no support for writing them. The only way an external array is written to a snapshot is through the api message writer.
This allows dart:io to avoid one copy of data read from files and sockets. This change only contains one use of the new API.

This profiler will write binary HPROF data to a user provided stream that
can later be viewed by tools such as the Eclipse Memory Analyzer.
While all user defined types are accurately described in the profile data,
internal types that are not self-describing appear as empty objects. This
will be addressed by a future change.

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.

launch an isolate running a different script. Finally.
Reviewers: This isn't as hard to review as it looks. Dive right in!
Siggi: Take a look at my test status file changes and make sure I'm
excluding the right stuff.
Much of the churn in the CL comes from moving ownership of the
import_map. It used to be set per-library and is now set per-isolate.
This caused a lot of superficial diffs.
DART EMBEDDING API CHANGES:
- Dart_IsolateCreateCallback now takes a script_uri and main argument
instead of a name_prefix argument. The script_uri argument allows
the callback to launch different scripts. The main argument is used
in creating the isolate debug name.
- Dart_CreateIsolate now takes script_uri and main arguments. These
are used to build the isolate's debug name.
- Dart_LibraryTagHandler, Dart_LoadScript, and Dart_LoadLibrary no
longer take an import_map.
- Added Dart_SetImportMap.
- Added Dart_RootLibrary to provide access to the root library for the
current isolate.
OTHER STUFF
Add a couple of tests for spawnUri -- the existing tests assume that
scripts end in a .js suffix which isn't going to work out for us.
Changed how the debug name for isolates get built a bit.
Refactored bin/main.cc a bit. Fixed some problems with error handling
while creating isolates.
Minor refactoring in builtin.dart to always pass is_windows rather
than relying on it being squirreled away.

Allow for the library tag handler to be setup for the isolate, instead of
while loading a script. This ensures that we can use #import on the boot strap libraries like builtin, uri etc.
This change results in a dart API change and corresponding modifications are
necessary in dartium and App Engine.

Dart strings with embedded '\0' characters cannot be faithfully
represented as a C string.
This change adds Dart_StringToBytes to the Dart API. This function
converts a Dart string to array of UTF-8 code units and returns a
length. Builtin::PrintString now calls Dart_StringToBytes instead of
Dart_StringToCString and, for I/O, fwrite is called instead of fprintf
with the string format specifier.

Prologue weak persistent handles are similar to weak persistent
handles but exhibit different behavior during garbage collections that
invoke the prologue and epilogue callbacks. While weak persistent
handles always weakly reference their referents, prologue weak
persistent handles weakly reference their referents only during a
garbage collection occurs that invokes the prologue and epilogue
callbacks. During all other garbage collections, prologue weak
persistent handles strongly reference their referents.
