Add versioned deprecation macros
These macros follow the recent changes in GLibs deprecation setup. We now annotate deprecated functions with the version they were deprecated in, and you can define the macro GDK_VERSION_MIN_REQUIRED to cut off deprecation warnings for 'recent' deprecations. At the same time, we introduce version annotations for new API and allow you to avoid 'recent' API additions by defining GDK_VERSION_MAX_ALLOWED.
