Terminology change: invalid handles are now called error handles.
Unhandled exceptions used to be a kind of valid handle. Now they are
a kind of error handle.
For the Dart_Invoke* functions, this means that the standard
error-checking blob drops from two tests to one test and is
harder to mess up.
Many other Dart api functions (Dart_ToString, for example) previously
dealt with unhandled exceptions by turning them into terse error
messages. Now these functions preserve information about the
exceptions and generate better error messages.
Changed Dart_HandleMessage to return success/failure. It seemed to fit.

Details:
Dart_IsValid becomes Dart_IsError (negated sense).
Dart_GetError now knows how to print a stack trace semi-nicely.
Dart_ExceptionOccurred -> Dart_IsUnhandledException.
Renamed ApiFailure class to ApiError to fit better.
ApiError now has a "data" pointer that points to either an error
message string or to an unhandled exception object.
Documentation changes aplenty.
