Switch to using OpenSSL target names in CMakeLists.txt
Cmake 3.0 was a switch to using targets and properties rather than
variables when linking different components together.
We follow that philosophy by dropping ${OPENSSL_CRYPTO_LIBRARIES} and
${OPENSSL_SSL_LIBRARIES} in favor of OpenSSL::Crypto and OpenSSL::SSL.

Reduce the repeated library dependence information
Cmake is generally good at tracking specified dependencies between
libraries. All that we need to do is to establish a dependency on
OpenSSL's libcrypto for 'gost_core', and then we can reduce the amount
of repeated dependencies for everything that links against 'gost_core'.

Make CMakeLists.txt work better with static OpenSSL libraries
The static OpenSSL libraries have some dependencies that need to be
recorded fofr everything that's linked against it. To achieve this,
we use ${OPENSSL_CRYPTO_LIBRARIES} and ${OPENSSL_SSL_LIBRARIES}
instead of ${OPENSSL_CRYPTO_LIBRARY} and ${OPENSSL_SSL_LIBRARY}.

WIP: Made changes to be able to build gost-engine as static library. Added gost-engine.h to be able to load engine as static engine for openssl.
Made gost_core library independent.
Corrected openssl version in cirrus.yml

Fixed bug when acpkm key meshing didn't apply at appropriate time
during TLS secure exchange.
Unify usage of 'num' variable of EVP_CIPHER_CTX for kuznetchik and
magma.

gost_crypt: process full available block in CFB and CNT mode
If at the input of the encryption function in the CFB mode we have
an integer number of blocks, then in the main loop all blocks will be
processed, except for the last one due to an incorrect border check.
The last block will be fully processed as a "partial" remainder, but
the initialization vector will not be updated. And, thus, the value
of IV will always be incorrect in this case.
This breaks stateless protocols due to an invalid initialization vector:
all messages except the first cannot be decrypted. (Naturally, we are
talking about a case with disabled key meshing, which does not allow
context recovery due to an erroneous implementation.)
It is worth noting here that the code for processing partial blocks
(both at the input of the encryption functions and at the output) is
a historically unnecessary artifact, since we do not set the
EVP_CIPH_FLAG_CUSTOM_CIPHER flag and, as a result, OpenSSL processes
partial blocks for us.
This patch corrects the checking of the main loop boundary.
A similar error is present in the code for the CNT mode, but there it
does not manifest itself in any way, because the restoration of the
state in this mode is impossible: even after disabling key meshing, we
still have the state-dependent transformation of the IV.
As an extra result of this fix, the code for processing partial blocks
can be completely removed now.
Provide cmake test if alignment requirement is strict
This is based on AX_CHECK_ALIGNED_ACCESS_REQUIRED from autoconf-archive.
Note, that on some arches unaligned access behavior could be changed at
runtime via prctl(1). Also, unaligned memory access is still slower (and
very slow on some arches) even if it's not strictly required.
