Common-opencl: do not release unused event. No harm done but it can produce
confusing debug messages.
Wpapsk-opencl, krb5pa-sha1-opencl: Faster LWS enumeration (no iterations).
Bugfixes for the new restart code in bench_handle_timer().
bench.c: For --test=0, make the OpenCL formats also do quick benchmarking
(for self-tests, not benchmark figures).
Merge branch 'unstable-jumbo' into bleeding-jumbo
