As documented by OpenSSL, it does not interact with session resumption
correctly:
https://www.openssl.org/docs/manmaster/ssl/SSL_set_verify_result.html
Sadly, netty-tcnative calls it, but we should be able to get them to
take it out because it doesn't do anything. Two of the three calls are
immediately after SSL_new. In OpenSSL and BoringSSL as of the previous
commit, this does nothing.
The final call is in verify_callback (see SSL_set_verify). This callback
is called in X509_verify_cert by way of X509_STORE_CTX_set_verify_cb.
As soon as X509_verify_cert returns, ssl->verify_result is clobbered
anyway, so it doesn't do anything.
Within OpenSSL, it's used in testdane.c. As far as I can tell, it does
not actually do a handshake and just uses this function to fake having
done one. (Regardless, we don't need to build against that.)
This is done in preparation for removing ssl->verify_result in favor of
session->verify_result.
