Fix Clang -Wexpansion-to-defined warning by deprecating QT_SUPPORTS
The C and C++ standards say it's undefined whether the preprocessor supports macros that expand to defined() will operate as an ifdef. Clang 3.9 started complaining about that fact. One solution was to change QT_SUPPORTS to check for zero or one, which means we need to change the #defines QT_NO_xxx to #define QT_NO_xxx 1. The C standard says we don't need to #define to 0, as an unknown token is interpreted as zero. However, that might produce a warning (GCC with -Wundef), so changing the macro this way is not recommended. Instead, we deprecate the macro and replace the uses with #ifdef/ndef.
