Make -Werror possible to control on a per-warning-class basis. While I was fixing up that code anyway, merge the handling of the -w, -W and [warning] argument and directives. Furthermore, make *all* warnings suppressible; any warning that isn't categorized now belong to category "other". However, for cleanliness sake an "other" option does not get listed in the warning messages. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
