Add pimctl to replace pimd -r

[troglobit]

For pimd 3.0 I'd like to see a pimctl replace pimd -r for showing state of VIFs and the multicast routing table. It could also be used to perform commands like reload/restart, flush and kill. Unlike a signal, pimctl would not return until pimd has completed the request.

Nothing fancy, but more along the lines of the smcroutectl tool I wrote for smcroute.

As of c8dd845 the new pimctl tool is quite useful. It has the following commands, and a separate man page:

Usage: pimctl [OPTIONS] [COMMAND]

Options:
  -b, --batch               Batch mode, no screen size probing
  -d, --detail              Detailed output, where applicable
  -i, --ident=NAME          Connect to named pimd instance
  -p, --plain               Use plain table headings, no ctrl chars
  -t, --no-heading          Skip table headings
  -v, --verbose             Verbose output

So I consider this issue resolved :smiley:
