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.

audio_stream_in_frame_size or audio_stream_frame_size can return 0 so
this needs to be checked before divide.

bt_uuid_to_le is currently broken if the src uuid is type 32 bits since
it does the conversion to 128 bits but still uses the original value to
swap instead of the coverted one.

Drop extra reference before exiting function.

This patch use lib/uuid library for uuids instead of local function.

This adds explicit typecasts to an inline function to make it C++
compatible. What follows is a sample error message from g++ when
compiling without this patch.
