[RFCv2 bluetooth-next 00/19] bluetooth: rework 6lowpan implementation

Hi,

This patch series is my second RFC for making btle 6lowpan into the right
direction.

I added hopefully all suggestions which I got from RFCv1. The interface address
will be assigned when the first l2cap chan connection gets in. This device
address will be get by "hci_copy_identity_address" bluetooth API function and
I hope this is the right function to get the "RPA device address".

Checkout commit message of Patch 19/19 to see how I used it.

Bad news are, I will start my master thesis shortly so I am not able to work
on this patch series anymore.

changes since v2:
 - Add patch "bluetooth: introduce l2cap chan priv data" to deal with private
   l2cap chan data when doing the final put, instead handling own heap
   allocation to do that.
 - remove patch "6lowpan: ndisc: don't remove short address" which was for
   802.15.4 handling only. It's mainline now.
 - following changes was done for new btle 6lowpan implementation:
    - Changing debugfs UAPI:
      - 6LoWPAN interface will be add/del on power on/off per hci dev. Depends
        on 6lowpan_enable is "1".
      - "6lowpan_control" is moved now to the hci debugfs entry and available
         if 6lowpan interface is also available only.
    - Setting device address is done when the first l2cap_chan connection comes
      in (ready callback). This will be done by hci_copy_identity_address and
      I hope this will be the RPA address. After first connection comes in
      the 6LoWPAN interface will came up.
      If last connection is lost, the device address will be 0...0.
      In general a device address of 0...0 indicates no connection and the
      interface can be set "up" while this.
    - Adding module_get/put to don't remove module while interfaces are
      there and other bug fixes.
    - Added TODO comment for multicast listener support.
