added dlog plugin, and default dlog logger for native resourcessubmit/tizen/20160512.051443accepted/tizen/wearable/20160513.004050accepted/tizen/tv/20160513.004124accepted/tizen/mobile/20160513.004024accepted/tizen/ivi/20160513.004146accepted/tizen/common/20160513.123222

Note: to enable plugin, it has to be loaded in configuration file
      (/etc/murphy/murphy.lua) by m:try_load_plugin('dlog') command;
      dlog support is enabled by default; use --disable-dlog
      configure command to build without dlog support
