Make gdb.base/a2-run.exp use $inferior_spawn_id and gdb_test_stdio
This one is a little more complicated than the other patches in this series, because of the exit status wrapper handling, requiring a little state machine. gdb/testsuite/ChangeLog: 2015-07-29 Pedro Alves <palves@redhat.com> * gdb.base/a2-run.exp (saw_usage, saw_exit_wrapper) (saw_spurious_output): Expect inferior output from $inferior_spawn_id. Use gdb_test_stdio.
