Subject: [PATCH iproute2-next 0/2] ss: remove implicit dependency on rpcinfo

ss uses rpcinfo to get info about rpc service sockets. However, rpcinfo
is not part of iproute2 and it's an implicit dependency for ss.

This series uses libtirpc[1] API to implement the same feature of
rpcinfo for ss. This makes it possible to get info about rpc sockets,
provided ss is compiled with libtirpc support.

As a nice byproduct, this makes ss provide info about some ipv6 rpc
sockets that are not displayed using 'rpcinfo -p'.

- patch 1 adds a configure function to check for libtirpc;
- patch 2 actually rework ss to use libtirpc.

  configure: add check_libtirpc()
  ss: remove an implicit dependency on rpcinfo
