gost28147: add support for CryptoPro key meshing per RFC 4357
* cipher/gost28147.c (gost_do_set_sbox, cryptopro_key_meshing,
CryptoProMeshingKey, gost_encrypt_block_mesh): New.
(_gcry_cipher_spec_gost28147_mesh): New cipher with keymeshing,
(_gcry_cipher_spec_gost28147): Remove OIDs for this cipher should not
be selected using these OIDs (they are for CFB with keymeshing).
* cipher/cipher.c (cipher_list, cipher_list_algo301): add
_gcry_cipher_spec_gost28147_mesh.
* src/gcrypt.h.in (GCRY_CIPHER_GOST28147_MESH): New cipher with
keymeshing.
* doc/gcrypt.texi (GCRY_CIPHER_GOST28147_MESH): Add definition.
* tests/basic.c (check_gost28147_cipher, check_gost28147_cipher_basic):
Run basic tests on GCRY_CIPHER_GOST28147_MESH.
