porting linux bt drivers/system to freebsd

im guessing it would be as trivial as rewriting the linux
system calls to freebsd system calls and retaining the data required
to communicate with bt devices

if hacketry needed, we can run some sort of layer over the linux
emulation layer which allows the linux drivers to be emulated on
freebsd, not sure if linuxulator does drivers though

or we can just have a module with linux emulator bits thats just for
the bt stack
