Final fix to the SIGALRM problem. My previous attempt at installing a restarting
signal handler was correct but incomplete (only worked on some platforms).
Office OpenCL formats: Once again revert to using scalar code for all devices
due to what seem to be driver bugs.
Rename CL_VERSION_1_0 macro to HAVE_OPENCL to clean the code a bit.
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).
