3 - Remove support for clients claiming to support any standard
4 ciphersuites that we can actually provide. (As of modern
5 OpenSSL versions, it's not necessary to fake any standard
6 ciphersuite, and doing so prevents us from using better
7 ciphersuites in the future, since servers can't know whether an
8 advertised ciphersuite is really supported or not.) Some
9 hosts--notably, ones with very old versions of OpenSSL or where
10 OpenSSL has been built with ECC disabled-- will stand out
11 because of this change; TBB users should not be affected.
12 This implements the client side of proposal 198.
