Introduction of a new "bpf" command that displays information about

loaded eBFP (extended Berkeley Packet Filter) programs and maps.
Because of its upstream fluidity, the capabilities of this command
will be an ongoing task.  In its initial form, the command displays
the addresses, basic information, and key data structures of eBPF
programs and maps.  It also translates the bytecode, and disassembles
the jited code, of loaded eBPF programs.
