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.

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.

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.
