Create handle objects for stdin/stdout/stderr. For Mac OS and
Linus the file descriptor numbers are used but on Windows the
handles are wrapped in an object.
The system handles for stdin/stdout/stderr on Windows does not
support overlapped IO. To mittigate this the write calls are
performed synchronously and the read calls are preformed in a
thread which posts the result through the completion potr where
it is handled as if it originated from overlapped IO through the
completion port. For now each call to read starts a new thread.

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.

Have both async and sync version for the file operations. The
thinking is that once you have used an async operation you will
not be allowed to use a sync one. Only sync versions currently
implemented.
Instead of having one input and one output stream associated with a
file we create new streams whenever needed. These get their own
underlying file descriptor so they do not interfere. This means
that FileStreams have to be explicitly closed.

- Dart_Result is gone. Dart_Handle mostly replaces it.
- Name/signature changes
- IsValidResult -> IsValid
- GetErrorCString -> GetError
- many more...
- Make details of persistent handle freelist private.
- Add persistent "True" handle to api state.
Things I am not doing in this changelist:
- Documentation updates
