Note that they are documented by being declared in bio.h. The OpenSSL
documentation in form of .pod files isn't complete yet.
The best thing to do with functions that you want removed is to wrap
them in a #ifndef OPENSSL_NO_DEPRECATED clause. If you look, you will
see that we've already done that with some functions.

The relevant question is "are they used". If we're doing something
that forces others to rewrite or tweak their applications, we need to
give them ample warning if we can.
