rtnl_link: implement IFLA_INFO_DATA for bridges

Browse Source 
* xlat/rtnl_ifla_info_data_bridge_attrs.in: New file.
* rtnl_link.c: Include xlat/rtnl_ifla_info_data_bridge_attrs.h.
(ifla_info_data_bridge_nla_decoders): New decoder dispatcher table.
(decode_nla_linkinfo_data_bridge, decode_nla_linkinfo_data): New
functions.
(ifla_linkinfo_nla_decoders) <IFLA_INFO_DATA>: Use
decode_nla_linkinfo_data as a decoder.
