Prepare addition of X509_STORE_CTX_get1_{certs,crls}(3)

Prepare addition of X509_STORE_CTX_get1_{certs,crls}(3)

X509_STORE_get1_{certs,crls}(3) was added to the OpenSSL 1.1 API with the
usual care. At some point later it was noticed that they didn't deal with
an X509_STORE at all, but rather with an X509_STORE_CTX, so were misnamed.
The fact that X509_STORE_CTX and X509_STORE have their roles reversed when
compared to other FOO vs FOO_CTX in this API may or may not be related.

Anyway, the X509_STORE versions will be demoted to compat defines and the
X509_STORE_CTX will be added to match OpenSSL 1.1 API more closely. This
was pointed out by schwarze a long time ago and missed in a few bumps.
Hopefully we'll manage to do it this time around.
