Add a debug-CLI leak-checker
leak-check { <any-debug-cli-command-and-args> } Hint: "set term history off" or you'll have to sort through a bunch of bogus leaks related to the debug cli history mechanism. Cleaned up a set of reported leaks in the "show interface" command. At some point, we thought about making a per-thread vlib_mains vector, but we never did that. Several interface-related CLI's maintained local static cache vectors. Not a bad idea, but not useful as things shook out. Removed the static vectors.
