Add a CHANGES entry for the deprecated cleanup functions

 Changes between 1.0.2g and 1.1.0  [xx XXX xxxx]

  *) Make various cleanup routines no-ops and mark them as deprecated. Most

     global cleanup functions are no longer required because they are handled

     via auto-deinit (see OPENSSL_init_crypto and OPENSSL_init_ssl man pages).

     Explicitly de-initing can cause problems (e.g. where a library that uses

     OpenSSL de-inits, but an application is still using it). The affected

     functions are CONF_modules_free(), ENGINE_cleanup(), OBJ_cleanup(),

     EVP_cleanup(), BIO_sock_cleanup(), CRYPTO_cleanup_all_ex_data(),

     RAND_cleanup(), SSL_COMP_free_compression_methods(), ERR_free_strings() and

     COMP_zlib_cleanup().

  *) --strict-warnings no longer enables runtime debugging options

     such as REF_DEBUG. Instead, debug options are automatically

     enabled with '--debug' builds.
