[PATCH 0/3] gost28147: implement KeyMeshing per RFC 4357

[dbaryshkov at gmail.com]

RFC 4357 defines a special procedure of changing key and IV each 1024
bytes. This procedure should be used for CFB-encrypted data (e.g. CMS
files). Implement support for this key meshing. These changes were asked
for by AltLinux team implementing support for RFC 4490 in gpgsm.
