Added the preprocessor macro Q_DECL_DEPRECATED_X 

Added a macro to provide deprecation warnings with a custom text.  If
the compiler does not support the feature, it falls back to
Q_DECL_DEPRECATED instead.

Currently supports msvc, gcc, and clang.  The armcc documentation didn't
show that the feature was available.
