Parses a string containing debugging options
into a %guint containing bit flags. This is used
within GDK and GTK+ to parse the debug options passed on the
command line or through environment variables.
If @string is equal to "all", all flags are set. Any flags
specified along with "all" in @string are inverted; thus,
"all,foo,bar" or "foo,bar,all" sets all flags except those
corresponding to "foo" and "bar".
If @string is equal to "help", all the available keys in @keys
are printed out to standard error.
