Have the trace_contention_*() tracepoints consistently include
adaptive spinning. In order to differentiate between the spinning and
non-spinning states add LCB_F_MUTEX and combine with LCB_F_SPIN.
The consequence is that a mutex contention can now triggler multiple
_begin() tracepoints before triggering an _end().
Additionally, this fixes one path where mutex would trigger _end()
without ever seeing a _begin().
