net.c: fix printing AF_BLUETOOTH socket addresses

Browse Source 
* xlat/hci_channels.in: New file.
* net.c (print_sockaddr_data_raw): New function.
(print_sockaddr): Use it.
[HAVE_BLUETOOTH_BLUETOOTH_H]: Include "xlat/hci_channels.h".
[HAVE_BLUETOOTH_BLUETOOTH_H] (print_sockaddr_data_bt): Fix printing
sockaddr_hci, sockaddr_sco, sockaddr_rc, and sockaddr_l2 structures.
