Disable fastgen by default until it is fixed. The passed eeltype and vdwtype are not comparable to the ones of OCL/CUDA enums (e.g. eelOclCut)
Fix fastgen (not in a nice way). Flavor generation works correctly now
set environment OCL_FASTGEN to enable (disabled by default until further testing)
With this fix adh_cubic_vsites and pme_verlet_vsites.mdp will not complain about missing
kernels
