Immediate use-case is SPMC. Next is MPSC, then I will generalize

ck_queue: Add CK_?LIST_MOVE operation.
...
This operation is of format:
CK_S*LIST_MOVE(a, b, linkage) and is equivalent to intializing
a with the contents of b. This is done in a manner that is atomic
with respect to readers. Read-only operations are still valid in
b, but behavior is undefined for write-side operations on b after
a MOVE operation.
