Remove the X9.62 prime239v{1,2,3} curves
While RFC 3279 allows these curves for use in X.509 certificates (*), no one actually does this. Certs using these curves cannot be used for TLS and the curves aren't accepted by FIPS either. codesearch shows no actual uses of these curves, only their OIDs are listed. At this point these have become useless historical baggage. ok jsing (*) Of the 27 curves listed in RFC 3279 the only one that seems to have seen actual use in certificates is P-256.
