[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-1.diff.txt

in this revision i have moved all bluetooth configuration files under 
/etc/bluetooth. bluetooth.device.sample is now called 'default.conf' and 
file that contain device specific overrides called '$dev.conf' (i.e. 
'ubt0.conf').

so, '/etc/rc.d/bluetooth start $dev' does the following

1) sets hardwired defaults (for backward compatibility)

2) reads up /etc/bluetooth/default.conf (if any)

3) reads up /etc/bluetooth/$dev.conf (if any)

4) starts the stack

even though /etc/bluetooth/{default,$dev}.conf are not exactly shell 
scripts they are still kinda like shell scripts :) these files should 
follow sh(1) syntax to set the variable, comments etc.

the parser in bluetooth_read_conf() is very simple and value of a 
variable is still used in sh(1) eval. so one must be careful when 
editing these files.

is this looks like something? i also could write 
bluetooth.device.conf(5) man page that describes the parameters as well 
as the syntax of the files.

thanks,
max
