[RFC] rc.d integration for the bluetooth subsystem

[Maksim Yevmenkin]

All,

please find next revision of bluetooth-rc stuff at

http://people.freebsd.org/~emax/bluetooth-rc-3.diff.txt

in this revision i have moved default bluetooth.device.conf 
configuration file under /etc/defaults. device specific overrides are 
under /etc/bluetooth and called '$dev.conf'. the rest if quite the same, 
so /etc/rc.d/bluetooth start "foo"

1) sets hardwired defaults (for backward compatibility)

2) reads /etc/defaults/bluetooth.device.conf (if any)

3) reads /etc/bluetooth/foo.conf

i also removed offending { } in while loop stdin redirection. if this is 
acceptable then i will commit this and start working on 
bluetooth.device.conf(5) man page and handbook chapter updates.

thanks,
max
