if given script, which executes under the debug tracer, fails before
xtrace_restore() is called, the BASH_ARGC[] will miss all the arguments
which were passed down till that very point. Similar case can be
experienced after tracer is disabled as then all the arguments hold by
BASH_ARG{C,V}[] become unavailable (i.e. until tracer is enabled again).
Since there's no actual benefit from toggling the extdebug (in fact, it
could break DEBUG|RETURN traps if ever used), enable it once when
autotest_common.sh is sourced and keep it enabled throughout entire
execution of given script.
