Support for RFC 4357

[Dmitry Baryshkov]

Hello,

On February 9th I've sent three patches implementing support for a
part of RFC 4357 (key meshing for GOST 28147-89) [1]. This is required
to support CMS and encrypted private key files using GOST 28147-89
algorithm (see RFC 4490).

For a month there was no reaction on the ML. I'm trying to understand
now, if there are any issues with the patches themselves, with the
approach selected to implement it, or we should just wait  for some
time?
