things that may go wrong while invoking the dart api.
Here are the four types of error:
- ApiError = the user misused one of the dart apis
- LanguageError = a language-level problem, e.g. compiler error
- UnhandledException = an uncaught exception made its way to the embedder
- UnwindError = a forced isolate interrupt
This cl is the first of a series. I plan to move the point of
creation for LanguageErrors into the Parser, etc. I also plan to move
the longjmp's out of dart_api_impl.cc. I also also plan to implement
UnwindErrors later.
