revert commit 4108e77e:
remove "const" in pub_decode_gost_ec().
First commited on master branch on May 26, 2020 (see https://github.com/openssl/openssl/commit/7674e92324648b59786d86d8e9014bbaed4e6d07).

partially revert commit dbc8f478:
OpenSSL v.1.1.1 API has no function EC_GROUP_get0_field().
First commited on master branch on Feb 15, 2019 (see https://github.com/openssl/openssl/commit/fa1f03061037cbdac5369849a885c1191a2550d9).

checks OpenSSL v.3.0 API function calls:
OSSL_STORE_attach(), PEM_write_bio_X509_PUBKEY()/i2d_X509_PUBKEY_bio().
First commited on master branch on May 13, 2020 (see https://github.com/openssl/openssl/commit/6ab6ecfd6d2d659326f427dceb1b65ae1b4b012b).
First commited on master branch on Nov 29, 2019 (see https://github.com/openssl/openssl/commit/cb58d81e68c72ab0128e0a5fc6faa007f8632acd).

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.

(cherry picked from commit cf402dd4)

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.

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.

This branch is created for experiments with the patched OpenSSL version.
The patch implements Russian GOST TLS 1.2 and TLS 1.3 support in
OpenSSL.

Some parts of the patch are already included in OpenSSL 3.0, some are
not and possibly, will never be.

This branch is recommended for ditribution builders and those who want
make experiments. It MUST NOT be used instead of system OpenSSL.
