This PR separates another module that does not depend on complex gost-core, as part of addressing #496.
The module
gosttls12additionalcontains kexp15, kimp15, kdftree2012_256 and tlstree implemenation. This module depends only on OpenSSL and uses either the engine or the provider via the public OpenSSL API.The tests
test_tls12additional(formerlytest_keyexpimp) are enabled for this module with both the engine and the provider.In separate commit we fix kexp15/kimp15 functions to work with provider implementation (use EVP_MAC instead of EVP_MD).
