"slice mode" option seems to be unnecessary since it could be determined by -slices/max_nal_size.
default: SM_FIXEDSLCNUM_SLICE mode with cpu-number slices. -slices N: SM_FIXEDSLCNUM_SLICE mode with N slices. -max_nal_size: SM_SIZELIMITED_SLICE mode with limited size slices. Add FF_API_OPENH264_SLICE_MODE macro to remove this option after LIBAVCODEC_VERSION_MAJOR = 59.
