hashcat/OpenCL/m07300_a1-optimized.cl
Jens Steube 15ada5124e Further simplified the use of inc_hash_scrypt.cl without any speed regression, and updated all affected plugin kernels. Use m08900-pure.cl as a template. 
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.
