Most commands like 'show ospf neighbors' fail when protocol is not specified and there are multiple instances of given protocol type. This is annoying in BIRD 2, as many protocols have IPv4 and IPv6 instances. The patch changes that by showing output from all protocol instances of appropriate type. Note that the patch also removes terminating cli_msg() call from these commands and moves it to the common iterating code.
