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

a8eb611b1c Add HMAC-Streebog-512 (pure kernels) 
Implement HMAC based on GOST 34.11-2012 Streebog-512 as well as a test
case for it. Both the PyGOST + hmac python module and the VeraCrypt HMAC
for Streebog-512 were used as references. The kernels expect the digests
to be in big-endian order according to the RFC examples for Streebog.

Fix two bugs from commit 224315dd62.

 - Add hash-mode 11850: HMAC-Streebog-512 (key = $pass), big-endian
 - Add test case for hash-mode 11850
 - Bugfix for a3-pure Streebog kernels (modes 11700 and 11800)
 - Rename a few Streebog constants in interface.h
