Initial step towards the ability to reduce c-ares exported symbols
based on the 'visibility' attribute for GNUC and __global for Sun compilers, taking also in account __declspec function decoration for Win32 and Symbian DLL's. Introducing configure options --enable-hidden-symbols and --disable-hidden-symbols following libcurl's naming.
