Adds suport for the Japanese cipher Camellia with 256-bit keys as used
by VeraCrypt.
- Add Camellia header decryption checks to all VeraCrypt kernels
- Add test containers for remaining cipher combinations
Substitute long parameter lists in ~2900 kernel function declarations
with macros. This cleans up the code, reduces probability of copy-paste
errors and highlights the differences between kernel functions. Also
reduces the size of the OpenCL folder by ~3 MB.
