Add agl-service-steering-wheel

Add new binding service for steering wheel.
Right now it's for logitech g29 and build on reneses m3ulcb.
Had test on Daring Dab  3.99.2, 3.99.3, 4.0.0.
After this commit, we want to add some code for dashboard to use this binding.

[Modify 20170803]
  Deleted trailing whitespace in README.md
  Fixed typo enogh to enough
  Modfied .noconcurrency 0 to 1 for atomic
  Checked event valid by afb_event_is_valid
  Droped event when not enough memory by afb_event_drop
[Modify 20170804]
  Modify json path into afb_daemon_rootdir_open_locale
  Delete error.h for same ERRMSG define in af-steering-wheel-binding.h
  Delete install code in recipes because aglwgt do autoinstall
  Add verbs information
