Add support for reading proto id/name mappings from rt_protos.d directory. Allows users to have custom protocol values converted to human friendly names. Each file under rt_protos.d has the 'id name' format used by rt_protos. Only .conf files are read and parsed. Signed-off-by: David Ahern <dsa@cumulusnetworks.com>
Each file in this directory is an rt_protos configuration file. iproute2 commands scan this directory processing all files that end in '.conf'.
