opencl: work around a bug in some OpenCL drivers

We add a call to clFinish() just before blending kernels are started.
Without this synchronization point, reads to dev_in would often not return
the correct value for some OpenCL drivers (namely AMD).
This bug also depends on the module after which blending is called. One of the
affected ones is sharpen.
lenscorrection: fix for #9268
Remember style of the guide in clipping module.

Minor usability enhancement.

workaround for bug #9246 (doesn't cover all cases, but works for me)

Added enable/disable for block_on_focus() and updated
all code using it to disable on gui_cleanup() this fixes
issues with focus-out event being handled for "dead" widgets.

This reverts commit d00d9f566442870d78b37ec5b91cffadaf59f002.
