ck_ring: add reserve and commit interface to enqueue.

Browse Source 
This new interface allows for slot reservation to avoid additional
copy-overhead from consumer. The primary use-case is for the type-specialized
variant of ck_ring. The initial patch-set does not migrate enqueue and
dequeue to be implemented in terms of reserve and commit but will be a future
commit.
