Bluetooth: LE Secure Connections support

Hi,

First of all, appologies to all for this huge patch set. It's work from the past 6 months or so that wasn't releasable until the 4.2 specification goes public. That happened just some moments ago:

I'm sending the patches to the mailing list mainly for reference since Marcel will probably directly merge them from my tree. Any issues/fixes etc should be done on top of them.
