Change rand_pool_bytes_needed to handle less entropy than 1 per 8 bits

rand_pool_bytes_needed() was constructed in such a way that the
smallest acceptable entropy factor was 1 entropy bits per 8 bits of
data.  At the same time, we have a DRBG_MINMAX_FACTOR that allows
weaker source, as small as 1 bit of entropy per 128 bits of data.
The conclusion is that rand_pool_bytes_needed() needs to change to
support weaker entropy sources.  We therefore change the input of
entropy per byte to be an entropy factor instead.  This entropy factor
expresses how many bits of data it takes (on average) to get 1 bit of
entropy.

Fix regression with session cache use by clients

Commit d316cdcf6d8d6934663278145fe0a8191e14a8c5 introduced some extra
checks into the session-cache update procedure, intended to prevent
the caching of sessions whose resumption would lead to a handshake
failure, since if the server is authenticating the client, there needs to
be an application-set "session id context" to match up to the authentication
context.  While that change is effective for its stated purpose, there
was also some collatoral damage introduced along with the fix -- clients
that set SSL_VERIFY_PEER are not expected to set an sid_ctx, and so
their usage of session caching was erroneously denied.

Fix the scope of the original commit by limiting it to only acting
when the SSL is a server SSL.

[SM2_sign] add minimal EVP_PKEY functionality testing

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.

[SM2_sign] fix double free and return value

Currently, critical bugs prevent using SM2 signatures through the
`EVP_PKEY` interface: any application that managed to satisfy the
requirement of forcing SM3 as the message digest – even if this is
currently not possible transparently through the `EVP_PKEY` interface
and requires manually forcing the MD selection – would crash with a
segmentation fault upon calling the `SM2_sign()` function.

This is easily verified using the OpenSSL CLI to execute this critical
code path under the right conditions:
`openssl dgst -sm3 -hex -sign sm2.eckey /path/to/file/to/sign`

The issue is caused by a double free at the end of `SM2_sign()` in
`crypto/sm2/sm2_sign.c` in case of successful signature generation.
In addition, even if the double free was not causing segfaults,
the function returns the wrong return value in case of success (it
would return 0 rather than 1).

This patch fixes both problems.

openssl/ssl.h: restore some renamed public SSL_CTRL defines

Fixes #6022

In commit de4d764e3271, the following SSL_CTRL #define's where renamed

    SSL_CTRL_GET_CURVES        ->  SSL_CTRL_GET_GROUPS
    SSL_CTRL_SET_CURVES        ->  SSL_CTRL_SET_GROUPS
    SSL_CTRL_SET_CURVES_LIST   ->  SSL_CTRL_SET_GROUPS_LIST
    SSL_CTRL_GET_SHARED_CURVE  ->  SSL_CTRL_GET_SHARED_GROUP

The corresponding function-like macros (e.g, SSL_get1_curves(ctx, s)) were
renamed, too, and compatibility #define's were added. This was overlooked for
the above constants. Since the constants are part of the public interface,
they must not be removed for a minor release.

As a consequence the Qt5 configure check (and the build) fails.
