cf: Check for OpenSSL 3.0

Browse Source 
This check is admittedly lame.  But it's all I have time for at the
moment.  A better check would be a program that includes the correct
headers and succeeds if the OpenSSL version macro indicates it's at
3.0 or higher.  Or perhaps we could run the openssl(1) version command-
line and parse its output.  But checking for functions that are in 3.0
and not 1.1 will do for the time being.
