The EFD database does not state that the "ladd-2002-it-3" algorithm
assumes X1 != 0.
Consequently the current implementation, based on it, fails to compute
correctly if the affine x coordinate of the scalar multiplication input
point is 0.
We replace this implementation using the alternative algorithm based on
Eq. (9) and (10) from the same paper, which being derived from the
additive relation of (6) does not incur in this problem, but costs one
extra field multiplication.
The EFD entry for this algorithm is at
https://hyperelliptic.org/EFD/g1p/auto-shortw-xz.html#ladder-ladd-2002-it-4
and the code to implement it was generated with tooling.
Regression tests add one positive test for each named curve that has
such a point. The `SharedSecret` was generated independently from the
OpenSSL codebase with sage.
This bug was originally reported by Dmitry Belyavsky on the
openssl-users maling list:

1. For every named curve, two "golden" keypair positive tests.
2. Also two "golden" stock ECDH positive tests.
3. For named curves with non-trivial cofactors, additionally two "golden"
ECC CDH positive tests.
4. For named curves with non-trivial cofactors, additionally two negative
tests.
There is some overlap with existing EVP tests, especially for the NIST
curves (for example, positive testing ECC CDH KATs for NIST curves).
"Golden" here means all the values are independent from OpenSSL's ECC
code. I used sage to calculate them. What comes from OpenSSL is:
1. The OIDs (parsed by tooling)
2. The curve parameters (parsing ecparam output with tooling)
The values inside the PEMs (private keys, public keys) and shared keys
are from sage. The PEMs themselves are the output of asn1parse, with
input taken from sage.

The actual functionality of generating signatures through the `EVP_PKEY`
API is completely untested.
Current tests under the `EVP_PKEY` API
(`test/recipes/30-test_evp_data/evppkey.txt`) only cover `Verify` and
`Decrypt`, while encryption and signature generation are tested with
ad-hoc clients (`test/sm2crypttest.c`, `test/sm2signtest.c`) that do not
call the `EVP_PKEY` interface at all but soon-to-be private functions
that bypass it (cf. PR#5895 ).
It is my opinion that an ideal solution for the future would consist on
enhancing the `test/evp_pkey` facility and syntax to allow tests to take
control of the PRNG to inject known nonces and validate the results of
`EVP_PKEY` implementations against deterministic known answer tests, but
it is probably too late to work on this feature in time for next release.
Given that commit b5a85f70d8 highlights some critical bugs in the hook
between the `EVP_PKEY` interface and SM2 signature generation and that
these defects escaped testing and code review, I think that at least for
now it is beneficial to at least add the kind of "bogus" testing
provided by this patch:
this is a "fake" test as it does only verify that the SM2 `EVP_PKEY`
interface is capable of creating a signature without failing, but it
does not say anything about the generated signature being valid, nor
does it test the functional correctness of the cryptosystem.
