This patch creates new testcases in the Auster test suite to
test the support of multiple modify RPCs in flight feature.

Two new OBD_FAIL codes are added to allow several failure occurences
of the reint requests or replies. This is needed because the current
fail checks impose the OBD_FAIL_ONCE flag.
