Hi Dave,

Here is the Bluetooth pull request for 3.4, but first there is some things I
need to explain:
 - I'm pulling directly to you because due to the coding style issues that
   happened some days ago. We decided, after talk to John, to pull directly to
   you, so you can take a look before pull. I personally looked to the whole
   diff of this pull request and couldn't spot anything that doesn't seem
   specified in CodingStyle.
 - This is a big pull request. It happened that this is the busiest Bluetooth
   release cycle I have ever seen and I had to be away from development and
   maintainance for about one month. Putting these two facts together it
   happened that we have now more than 200 patches queued in the Bluetooth
   subsystem tree.

About the patches:
 - almost half of the patches is in the new Bluetooth Management interface, it
 finally reached a stable state regarding its API and we now enable it by
 - lots of Bluetooth LE patches. This implementation is still unstable but
   disabled by default.
 - some L2CAP layer refactoring to make our core code more generic and
 - New HCI monitor interface to monitor Bluetooth flow.
 - Lot of fixes and clean ups all over the Bluetooth subsystem.
