> Fix net::FileStream to handle all errors correctly.
> 
> This CL adds FileStream::Context::IOResult struct that's used to pass 
> results of IO operations inside FileStream::Context. Following bugs are 
> fixes:
> 
> 1. On POSIX net::FileStream::Read() and net::FileStream::Write() would
>    return a positive result in case of an error. This happens because 
>    POSIX errors are positive integers and FileStream was written with 
>    assumption that they are negative.
> 2. On Windows Seek() and Flush() errors were not handled correctly.
>    This is because CheckForIOError() was assuming that all error codes 
>    are negative, but RecordAndMapError() was mapping positive errors.
> 3. On Windows results of asynchronous ReadFile() and WriteFile() were
>    not handled correctly - ERR_IO_PENDING would be returned even when
>    operation completes synchronously.
> 
> Also added unittests to check that error codes are handled correctly 
> now.
