Add additional ioctl() values to rtc so that it can 'admit' the calling
thread into a red-black tree for tracking, set the execution slot pattern,
support for setting whether read() will yield or block.

like to also credit Marco Ballesio from Palm as well for the
multimedia insights. I omitted that in my first message. Hope the
