build: detect Qt functions required for building the gui * m4/acinclude.m4 (OCTAVE_CHECK_FUNC_QABSTRACTITEMMODEL_BEGINRESETMODEL): New macro to detect Qt functions QAbstractItemModel::beginResetModel and QAbstractItemModel::endResetModel. * configure.ac: Call it and disable the gui if the functions are not found.
