From: Philippe Mathieu-Daudé <philmd@linaro.org>

Address the comment added in commit 4629ed1e98
("qerror: Finally unused, clean up"), from 2015:

  /*
   * These macros will go away, please don't use
   * in new code, and do not add new ones!
   */

Mechanical transformation using:

  $ sed -i -e "s/QERR_INVALID_PARAMETER,/\"Invalid parameter '%s'\",/" \
    $(git grep -lw QERR_INVALID_PARAMETER)

Manually simplify qemu_opts_create(), and remove the macro definition
in include/qapi/qmp/qerror.h.
