avoid warning about deprecated Qprinter::setPaperSize function
* acinclude.m4 (OCTAVE_CHECK_FUNC_QPRINTER_SETPAGESIZE): New macro.
(OCTAVE_CHECK_QT_VERSION): Use it.
* octave-svgconvert.cc: Include config.h.
Use QPrinter::setPageSize if it is available instead of the deprecated
QPrinter::setPaperSize function.
