/** Set the severity to be used with write error messages which are potentially
caused by not using write type BURN_WRITE_SAO on fast blanked DVD-RW.
Normally the call burn_write_opts_auto_write_type() can prevent such
errors by looking for MMC feature 21h "Incremental Streaming Writable"
which anounnces the capability for BURN_WRITE_TAO and multi session.
Regrettable many drives announce feature 21h even if they only can do
BURN_WRITE_SAO. This mistake becomes obvious by an early write error.
If you plan to call burn_drive_was_feat21_failure() and to repeat the
burn attempt with BURN_WRITE_SAO, then set the severity of the error
message low enough, so that the application does not see reason to abort.
@param opts The option object to be manipulated
@param severity Severity as with burn_msgs_set_severities().
"ALL" or empty text means the default severity that
is attributed to other kinds of write errors.
