This set contains some improvements for bpftool's "visual" program dump option, which produces the control flow graph in a DOT format. The main objective is to add support for inline annotations on such graphs, so that we can have the C source code for the program showing up alongside the instructions, when available. The last commits also make it possible to display the line numbers or the bare opcodes in the graph, as supported by regular program dumps. v2: Replace fputc(..., stdout) with putchar(...) in dotlabel_puts().
