Bluetooth 4.0

[Takanori Watanabe]

Hi, I wrote somewhat incomplete Bluetooth LE with ATT protocol code.
It is developed with unionfs over FreeBSD-current as of r274584.

Kernel patch

Userland code
http://www.init-main.com/le_enable-20150302.tar.gz

It is intended to compatible is existing Bluetooth userland, but 
compatibility between kernel code is lost and
the userland compatibility may be broken.
