Turn on OPENSSL_NO_DEPRECATED by default.

Also introduce OPENSSL_USE_DEPRECATED. If OPENSSL_NO_DEPRECATED is
defined at config stage then OPENSSL_USE_DEPRECATED has no effect -
deprecated functions are not available.
If OPENSSL_NO_DEPRECATED is not defined at config stage then
applications must define OPENSSL_USE_DEPRECATED in order to access
deprecated functions.
Also introduce compiler warnings for gcc for applications using
deprecated functions
