Implement Bluetooth access to messages (Message Access Profile, MAP)

Title sais it basically.

This Profile is most often seen in Car kits, but also things like “Bluetooth Diallers” use it.

SFOS already has a nice database for messages, what’s missing is the API/bus glue to the bluetooth layer.

  1. Must: Allow reading messages and lists of messages from connected bluetooth device
  2. Should: Allow sending (text) messages from connected bluetooth device
  3. Nice-To-Have: Display Notifications as “messages” to connected bluetooth device
  4. Nice-To-Have: XMPP and other messaging applications using Sailfish messaging infrastructure
  5. Out-of-Scope: Any of the plethora of instant messaging apps/protocols implemented in their own app. This is not what is meant by messages here.
