CodeQL IncorrectNotOperatorUsage.ql rtrDcmppose.c rtrCLEAR() usages 

Maybe it was a single bit and '!' operator inverted a single bit, but it
 appears to be a 4-bit mask today.

TODO check rtrMARKED() this looks like it uses '&' operator is in use
 but from the context of a bitmask maybe this should be '|' operator.
