bluez: isolate btio.[ch] as a library and do cleanup

[Zhenhua Zhang]

Hi,

These patches move bluez/src/btio.[ch] out from source directory and make it identical with obex's btio.[ch]. So we can freely copy them among bluez, obex and ofono.

Regards,
Zhenhua

That's fine for me. I don't see any current function call so I have this patch. I will resend them and remove patch 3/4. Let me know if you have other suggestiosn.

I don't think removing this feature is a good idea. Even though there
aren't any current users of bt_io_set doesn't mean that there wont be in
the future. I remember e.g. discussions regarding AMP about applications
needing the ability to request a switch from BR/EDR to WLAN for an
active connection. This could e.g. be accomplished through a setsockopt
call. Other uses for setsockopt while a connection is open, or even
changing settings for an existing server socket might exist too.
