kfifo: add DEFINE_KFIFO and friends, add very tiny functions
Add DECLARE_KFIFO - macro to declare a kfifo and the associated buffer inside a struct
Add INIT_KFIFO - Initialize a kfifo declared by DECLARED_KFIFO
Add DEFINE_KFIFO - macro to define and initialize a kfifo as a global or local object
Add kfifo_size() - returns the size of the fifo in bytes
Add kfifo_is_empty() - returns true if the fifo is empty
Add kfifo_is_full() - returns true if the fifo is full
Add kfifo_avail() - returns the number of bytes available in the FIFO
Do some code cleanup
