Change subject: RSPRO: Add new ResetState{Req,Res}
......................................................................

RSPRO: Add new ResetState{Req,Res}

These commands are introduced to enable the server to request the
full reset of all state in a client or bankd.  This is particularly
useful in TTCN-3 tests, where we typically want to reset the state
between tests.
