build adjustments: CURL_HIDDEN_SYMBOLS no longer defined in config files
configure script now provides conditional definitions for Makefile.am that result in CURL_HIDDEN_SYMBOLS being defined by resulting makefiles when appropriate. Additionally, configure script option for symbol hiding control is now named --enable-symbol-hiding --disable-symbol-hiding. While still valid, old option name --enable-hidden-symbols --disable-hidden-symbols will be deprecated in some future release.
