Previously the length of the SM2 plaintext could be incorrectly calculated.
The plaintext length was calculated by taking the ciphertext length and
taking off an "overhead" value.
The overhead value was assumed to have a "fixed" element of 10 bytes.
This is incorrect since in some circumstances it can be more than 10 bytes.
Additionally the overhead included the length of two integers C1x and C1y,
which were assumed to be the same length as the field size (32 bytes for
the SM2 curve). However in some cases these integers can have an additional
padding byte when the msb is set, to disambiguate them from negative
integers. Additionally the integers can also be less than 32 bytes in
length in some cases.
If the calculated overhead is incorrect and larger than the actual value
this can result in the calculated plaintext length being too small.
Applications are likely to allocate buffer sizes based on this and therefore
a buffer overrun can occur.

This function needs to be power up tested as part of the FIPS validation and
thus it needs to be inside the provider boundary. This is realised by
introducing a new KDF "TLS13-KDF" which does the required massaging of

The 'file:' store loader only understood DER natively. With all the
whatever to key decoders gone, direct support for other binary file
formats are gone, and we need to recreate them for this store loader.
With these changes, it now also understands MSBLOB and PVK files.
As a consequence, any store loader that handles some form of open file
data (such as a PEM object) can now simply pass that data back via
OSSL_FUNC_store_load()'s object callback. As long as libcrypto has
access to a decoder that can understand the data, the appropriate
OpenSSL object will be generated for it, even if the store loader sits
in a different provider than any decoder or keymgmt.
For example, an LDAP store loader, which typically finds diverse PEM
formatted blobs in the database, can simply pass those back via the
object callback, and let libcrypto do the rest of the work.

This makes the 'file:' store loader only read the file, and only decode
down to a base level binary format, and simply pass that blob of data
back to the OSSL_FUNC_store_load() object callback.
This offloads the decoding into specific OpenSSL types to libcrypto,
which takes away the issue of origins, which provider is it that holds
the key (or other future types of objects).

When decoding a key and asking the keymgmt to import the key data, it
was told that the key data includes everything. This may not be true,
since the user may have specified a different selection, and some
keymgmts may want to be informed.
Our key decoders' export function, on the other hand, didn't care
either, and simply export anything they could, regardless.
In both cases, the selection that was specified by the user is now
passed all the way.

Previously all the SubjectPublicKeyInfo decoders were specific to a key
type. We would iterate over all them until a match was found for the correct
key type. Each one would fully decode the key before then testing whether
it was a match or not - throwing it away if not. This was very inefficient.
Instead we introduce a generic SubjectPublicKeyInfo decoder which figures
out what type of key is contained within it, before subsequently passing on
the data to a key type specific SubjectPublicKeyInfo decoder.

This has us switch from the 'structure' "pkcs8" to "PrivateKeyInfo",
which is sensible considering we already have "SubjectPublicKeyInfo".
We also add "EncryptedPrivateKeyInfo", and use it for a special decoder
that detects and decrypts an EncryptedPrivateKeyInfo structured DER
blob into a PrivateKeyInfo structured DER blob and passes that on to
the next decoder implementation.
The result of this change is that PKCS#8 decryption should only happen
once per decoding instead of once for every expected key type.
Furthermore, this new decoder implementation sets the data type to the
OID of the algorithmIdentifier field, thus reducing how many decoder
implementations are tentativaly run further down the call chain.
