[Development] Dropping the variadic version of QSKIP

[Albert Astals Cid]

Hi all, in 14cd2678396ed1450a72aeffa99c1504743ea415 a variadic version of QSKIP 
was added so that the old Qt4 version of
   QSKIP(statement, mode)
would compile on C++11 enabled compilers silently ignoring the mode.

This has a down side, it is causing that code like 
   QSKIP("HOLA");
gives 
  warning: ISO C99 requires rest arguments to be used [enabled by default]
when compiled with -pedantic and C++11

Furthermore, things like
  QSKIP("HOLA", SkipSingle);
don't compile anymore because moc complains
  main.cpp:11: Error: Macro argument mismatch.

So it doesn't seem it makes much sense to keep the variadic version of QSKIP 
to enable the compatibility with the old Qt4 syntax if moc is not accepting it 
anymore.

Would you guys accept a patch that drops the variadic version of QSKIP?

Cheers,
  Albert
