This patch adds the --type option to btgatt-server which allows
the source bdaddr type to be specified. If the option is not
provided, the source type defaults to BDADDR_LE_PUBLIC.
This also fixes a bug in that manifests itself in later kernels
that prevents an LE connection to be accepted when '0' is given for
the source address type, where '0' corresponds to BDADDR_BREDR.
