There are three symbols removed with OPENSSL_NO_SSL3_METHOD:
SSLv3 has been deprecated since 2015 (and broken since 2014: "POODLE"); it
should not have shipped in FreeBSD 11 (2016) or 12 (2018). No one should
use it, and if they must, they can use some implementation outside of base.
These symbols exist to request an explicit SSLv3 connection to a server.
There is no good reason for an application to link or invoke these symbols
instead of TLS_method(), et al (née SSLv23_method, et al). Applications
that do so have broken cryptography.
Define these symbols for some trite definition of ABI stability, but remove
the functionality again -- restore r361392.
