One of the advantages of the new FileChannel-based implementation
is that we no longer need a separate PlatformFileDescriptor.  The
FileChannelImpl serves that need, without the need for an extra
object and extra indirection.  Right now FileChannelImpl is not
sub-classed, but it would be perfectly reasonable and a minor
change to use implementation-specific FileChannel[Impl] classes.
