ck_queue: Fix CK_LIST_INSERT_HEAD.
...
CK_LIST_INSERT_HEAD was incorrectly managing prev
pointer on insertion to non-empty list. This bug
would cause erroneous behavior on CK_LIST_REMOVE
to non-head elements. Unit test will be updated
for this regression.

ck_bytelock: Fix downgrade path from writer to reader.
...
An off-by-one was introduced in downgrade path from writer.
This can cause deadlock if a writer downgrades from a write lock.

ck_ring: Add a work-around for compiler bug(s) in ck_ring_dequeue_spmc.
...
Both LLVM-backed compilers and GCC incorrectly treat
a barrier-sandwiched load as a loop invariant in dequeue_spmc.
Forcing volatile atomic load semantics generates the right
thing.
Thanks to Devon O'Dell and Abel Mathew for help in catching
this issue.

ck_backoff: Replace ck_backoff_eb with ck_backoff_gb.
...
The distinction between additive/exponential implementation
and geometric implementation does little but confuse users.
The terminology used in ck_backoff now reflects terminology
used in literature.
ck_backoff_gb has been removed.

regressions/ck_ring: Fix use of uninitialized data.
...
Execution history exists such that first thread will dequeue
from an uninitialized ring buffer. The unit test has been
(un)fortunate in that it would busy-wait during dequeue.
Full barrier semantics will enforce visibility.
