Add 2 attributes to the interfaces functions
- externally_visible: avoid gcc to remove the function when lto is enabled
- visibility("default"): default == public... Allow to hide all others symbols: see http://gcc.gnu.org/wiki/Visibility for details
onepad:
* Remove __cplusplus define, everythings is in C
* define 2 interfaces functions with EXPORT_C_ instead of CALLBACK.
cmake:
* add recent added .h files
* add fvisibility optimization. Plugins size was reduced of ~10% much more than expected :)
