Updated kernel declarations from "KERNEL_FQ void HC_ATTR_SEQ" to "KERNEL_FQ KERNEL_FA void". Please update your custom plugin kernels accordingly. Added spilling size as a factor in calculating usable memory per device. This is based on undocumented variables and may not be 100% accurate, but it works well in practice. Added a compiler hint to scrypt-based kernels indicating the guaranteed maximum thread count per kernel invocation. Removed redundant kernel code 29800, as it is identical to 27700, and updated the plugin.
