- Inherit most SSL options for the doh handle but not SSL client certs,
SSL engine, SSL version, SSL ciphers, SSL id cache setting,
SSL kerberos or SSL gss-api settings.
My thinking for the options not inherited is they are most likely not
intended by the user for the DOH transfer. I did inherit insecure
because I think that should still be in control of the user.
Prior to this change doh did not work for me because CAINFO was not
inherited. Also verbose was set always which AFAICT was a bug (curl#3660).
