Port ADB over network and ability to hide the notification

Port "Option to hide Adb notification icon (2/2)"

From: Ricardo Cerqueira <cyanogenmod@cerqueira.org>
Framework: Forward port ADB over network (Part 2 of 2)

Includes:
- ADB Over Network, integration of the adb-host mode (already present)
  The feature can be used/tested without the Settings part:

    setprop service.adb.tcp.port 5555

  Note: This ADB setting is not persistent (for security purpose) and
  require init.rc implementation event like this : http://bit.ly/AdbTcpIP

Use custom ADB over wifi property

* Use a custom system property to trigger the real one, so we avoid
  running afoul of any SELinux CTS requirements.
