Practical example: a client supporting version 2 of wl_output will wait for the wl_output.done event before starting wl_output-related operations. However, if the server only supports version 1, no event will ever come, and it must fallback to use the wl_output.geometry event alone. Without this macro, it cannot check for that in a nice way. This patch introduces the same #defines in both server and client headers. We rely on both being generated from the same XML file and https://gcc.gnu.org/onlinedocs/cpp/Undefining-and-Redefining-Macros.html to not cause compiler errors or warning due to redefinitions. We also assume that no-one uses the same name in the same interface for both a request and an event. If this patch does cause grief due to identical redefinitions, the contingency plan is to change the generator to produce #ifndef/#define/#endif instead of just #define.
