error: Infrastructure to track locations for error reporting
New struct Location holds a location. So far, the only location is LOC_NONE, so this doesn't do anything useful yet. Passing the current location all over the place would be too cumbersome. Hide it away in static cur_loc instead, and provide accessors. Print it in error_report(). Store it in QError, and print it in qerror_print(). Store it in QemuOpt, for use by qemu_opts_foreach(). This makes error_report() do the right thing when it runs within qemu_opts_foreach(). We may still have to store it in other data structures holding user input for better error messages. Left for another day.
