freebsd/x86: Allow and override fence instructions to match kernel environment.
...
This is mostly based off of Olivier's (cognet@) work. I was considering
importing in __mbk but realistically, doesn't warrant the refactor.

ck_pr/x86_64: cleanup documentation around semantics.
...
A note has also been added around some ambiguity with respect to WC
memory and relaxed memory semantics (so, heavier-weight mfence semantics
for strict acquire-release interface).
All fences related to atomic operations have been removed as they were
just unnecessary, and so, confusing.

Quiet implicit fallthrough compiler warnings.

Annotate fall through cases in switch statements where that behavior is
desirable to quiet compiler warnings with the -Wimplicit-fallthrough
flag. The annotation format used is supported by both GCC and Clang.

ck_ring.h: make _ck_ring_enqueue_mp less failure happy
...
With preemption, it is possible for _ck_ring_enqueue_mp to have a
snapshot of p_head so stale with respect to the later snapshot of
c_head that a comparison modulo (small) ring size will erroneously
conclude that the ring is full.
Detect that case and retry rather than failing. We only retry when
the enqueuers have made global forward progress, so the first loop
is as lock-free as it ever was.
Bonus: the new condition should be marginally faster.

configure: Fix usage with busybox.
...
expr as provided by busybox doesn't know about --, while most other
implementations require it, or it'd try to interpret --prefix=whatever as
one of its own options. To fix this, we just remove the first two characters
of the option before calling expr, rendering -- useles.
