gmacros.h: Complete the use of GLIB_UNAVAILABLE_MACRO
Fixes #2376 (closed).
This MR
- adds
GLIB_AVAILABLE_MACRO_IN_*
where needed ingmacros.h
, or a comment when such use is not possible; - fixes
GLIB_UNAVAILABLE_MACRO
andGLIB_DEPRECATED_MACRO_FOR
so that these macros print their arguments correctly.
