5de004103a Replace kernel parameter lists with macros 
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.

47bd838e25 Add VeraCrypt Streebog support 
VeraCrypt added the possibility to use Streebog-512 as hashing algorithm
for the key derivation. This commit adds the necessary VeraCrypt kernels
as well as additional HMAC-Streebog kernels.

 - Add hash-mode 13771: VeraCrypt PBKDF2-HMAC-Streebog-512 + XTS 512 bit
 - Add hash-mode 13772: VeraCrypt PBKDF2-HMAC-Streebog-512 + XTS 1024 bit
 - Add hash-mode 13773: VeraCrypt PBKDF2-HMAC-Streebog-512 + XTS 1536 bit
 - Add hash-mode 11750: HMAC-Streebog-256 (key = $pass), big-endian
 - Add hash-mode 11760: HMAC-Streebog-256 (key = $salt), big-endian
 - Add hash-mode 11860: HMAC-Streebog-512 (key = $salt), big-endian
 - Add test suite for hash-modes 11750, 11760 and 11860
 - Improve pure Streebog kernels

224315dd62 Add pure kernels and tests for Streebog hashes 
Complete Streebog support with pure kernels that allow for passwords
longer than 64 characters. Provide generic inc_hash_streebog files
for future Streebog-based hash modes (HMAC, PBKDF2, VeraCrypt).

Include streebog support in the test suite. For this, python module
PyGOST is needed. Also add clarification to hash mode description
stating that Streebog hashes are expected in big-endian byte order.
There are several implementations, including PyGOST, which default
to little-endian byte order, while the RFC examples are big-endian.

 - Add pure kernels for hash-mode 11700 (Streebog-256)
 - Add pure kernels for hash-mode 11800 (Streebog-512)
 - Tests: Add hash-modes 11700 (Streebog-256) and 11800 (Streebog-512)
