mlippautz@google.com 94502c10ea Checks CObject lengths in native API. 
Also converts the API to use intptr_t instead of a mixture of int64_t and int. Internally all variable length objects have lengths and maximum values represented as intptr_t (actually Smi ranges). In order to check for these maximum lengths we need to have a common type for 32 and 64 bit platforms.

Helping constructs like IOBuffer can still use 64bit lengths, but have to check that there values are actually in the domain of intptr_t as soon as internal objects are created.

Addresses issue 4314.

asiva@google.com b4d9e0d620 Auto create ApiLocalScope before calling native functions, this ensures that 
native functions do not have to call Dart_EnterScope/Dart_ExitScope
when they callback into the VM.

Remove Dart_EnterScope/Dart_ExitScope calls around native functions in 'bin'
directory.

asiva@google.com 1e0c98714b Make writes consistent across socket and file synchronous/asynchronus writes in terms of truncation semantics (reports an argument error if the list element contains a non byte value). 
Remove Common_IsBuiltinList as it is not used anymore

Change synchronous file writes to use Dart_TypedDataAcquireData and
Dart_TypedDataReleaseData since the buffer object is always a Uint8List
instead of the more expensive Dart_ListGetAsBytes.

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.

sgjesse@google.com cdc29b23f0 Add error handling to random access file 
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.

sgjesse@google.com 84836f8c56 Error reporting on File in dart:io 
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.

sgjesse@google.com b4d571dcdd Handle stdio redirection in standalone VM 
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.
