vfs/poll: round timeout up to next full tick.  Calling poll() with timeout less than half tick (thus MSEC2TICK(timeout) => 0) caused returning error with EAGAIN. Instead of rounding timeout down, value should be rounded up. Open Group spec for poll says:  "Implementations may place limitations on the granularity of timeout intervals. If the requested timeout interval requires a finer granularity than the implementation supports, the actual timeout interval will be rounded up to the next supported value."

IOCTLS.  Separate wireless character driver IOCTL commands from wireless network driver IOCTL commands.  Move from wireless.h to ioctl.h.
