We have the logic for setting defaults for paths and maps in propsel.c. By pre-setting conf values with defaults in load_config(), we generate irritating log messages like 'features = "0" (setting: multipath.conf defaults/devices section)' if multipath.conf doesn't contain a features setting at all. For some config settings, we need to use declare_def_snprint_defint() now to make sure "multipathd show config" prints all defaults correctly. To avoid confusion, we don't do this for "max_sectors", because multipathd leaves this untouched by default.
