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

[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
[Modify 20170808]

+====
+<br>	These is a sample recipes for af-steering-wheel-binding, you can just add that recipes into your project and bitbake.
+<br>	Sample Recipes: agl-service-steering-wheel_0.1.bb
+
+How to use
+====
+For AGL Application
+----
+<br>1 add these code below into config.xml
+```
+  <param name="steering-wheel" value="ws"/>
+```
+<br>2 add WebSocket into qml file and subscribe event name what you need.
+<br>You can find a file named [token-websock.qml] in app-framework-binder.git.
+<br>It's a template for qml. You need modify these informations to connect agl-service-steering.
+```
+property string address_str: "ws://localhost:5555/api?token=3210"
+property string api_str: "steering-wheel"
+property string verb_str: ""
+```
+
+For demo application
+----
+<br>1 you can run this service by shell script
+```
+afb-daemon --token=3210 --ldpaths=${steering-wheel-library-path} --port=5555 --rootdir=. &
+```
+<br>2 use afb-client-demo to get event.
+```
+afb-client-demo ws://localhost:5555/api?token=3210
+steering-wheel list
+steering-wheel subscribe { "event" : "EngineSpeed" }
+steering-wheel unsubscribe { "event" : "EngineSpeed" }
