crypto/bn/asm/x86_64-gcc.c: remove unnecessary redefinition of BN_ULONG

This module includes bn.h via other headers, so it picks up the
definition from there and doesn't need to define them locally (any
more?).  Worst case scenario, the redefinition may be different and

Simplify SSL_get_servername() to avoid session references

Ideally, SSL_get_servername() would do exactly as it is documented
and return exactly what the client sent (i.e., what we currently
are stashing in the SSL's ext.hostname), without needing to refer
to an SSL_SESSION object.  For historical reasons, including the
parsed SNI value from the ClientHello originally being stored in the
SSL_SESSION's ext.hostname field, we have had references to the
SSL_SESSION in this function.  We cannot fully excise them due to
the interaction between user-supplied callbacks and TLS 1.2 resumption
flows, where we call all callbacks but the client did not supply an
SNI value.  Existing callbacks expect to receive a valid SNI value
in this case, so we must fake one up from the resumed session in
order to avoid breakage.

Otherwise, greatly simplify the implementation and just return the
value in the SSL, as sent by the client.

Restore historical SSL_get_servername() behavior

Commit 1c4aa31d79821dee9be98e915159d52cc30d8403 modified the state machine
to clean up stale ext.hostname values from SSL objects in the case when
SNI was not negotiated for the current handshake.  This is natural from
the TLS perspective, since this information is an extension that the client
offered but we ignored, and since we ignored it we do not need to keep it
around for anything else.

However, as documented in https://github.com/openssl/openssl/issues/7014 ,
there appear to be some deployed code that relies on retrieving such an
ignored SNI value from the client, after the handshake has completed.
Because the 1.1.1 release is on a stable branch and should preserve the
published ABI, restore the historical behavior by retaining the ext.hostname
value sent by the client, in the SSL structure, for subsequent retrieval.

Fix segfault in RSA_free() (and DSA/DH/EC_KEY)

`RSA_free()` and friends are called in case of error from
`RSA_new_method(ENGINE *e)` (or the respective equivalent functions).

For the rest of the description I'll talk about `RSA_*`, but the same
applies for the equivalent `DSA_free()`, `DH_free()`, `EC_KEY_free()`.

If `RSA_new_method()` fails because the engine does not implement the
required method, when `RSA_free(RSA *r)` is called,
`r->meth == NULL` and a segfault happens while checking if
`r->meth->finish` is defined.

This commit fixes this issue by ensuring that `r->meth` is not NULL
before dereferencing it to check for `r->meth->finish`.

Fixes #7102 .
