Now all both sync and async methods on File and RandomAccessFile
should have correct error handling.
Changed readByte and readByteSync to return -1 instead of
reporting an error when end of file is reached. It seems to make
the most sense.
The amount of boiler-plate code in both the native functions and
native port functions in file.cc is growing. Maybe we should
consider some refactoring, e.g. with a table of the expected
argument types for each native port functions together with known
position of the FILE* argument.

This implements consistent error reporting on all methods on File in dart:io. The async onError method is called with an exception argument which is the same exception as would have been thrown from the corresponding sync method.
The one method on Directory which already did this has been updated as well.

The recent change to epoll on Linux and kqueue on Mac OS for getting
notifications from file descriptors caused the redirection of stdin,
stdout and stderr for the stand alone VM to stop working.
On Linux epoll failed when file descriptor 0, 1 or 2 redirected from
or to a file war registered. On Mac OS there was just no events
generated from kqueue.
The streams created for stdio, stdout and stderr is now of the correct
type and for file redirections no longer a socket object holding a
file descriptor for a regular file.
Added testing of stdio redirection using both pipes and files. These
tests are currently skipped on Windows.
Fixed handlin of short socket read when reading the process exit code.
Always close the socket port when not waiting for any events.

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
