Add a preprocessor protocol name variable
Add a preprocessor protocol name variable

We should convert - to _ in the preprocessor protocol name since - will
lead to a new token, but we don't since it is better to fail early here
and the official wayland-scanner doesn't do this either. The generated
c++ header will give a compiler error when being used which gives the
user a chance to change the protocol name.
