ADC: Fix forgotten FARs

CAN: Add a new CAN upper-half interface, can_txready(), that can be used to break deadlock conditions in certain CAN hardware that supports queuing of TX messages

PWM: Add support for multiple output channels per timer

Named semaphores:  Bad cast in sem_close().  Fixed by reordering fields of struct nsem_inode_s so that the cast will work
