Do we really need this bit of info?  Is CERT_STATUS_REV_CHECKING_ENABLED
not enough?

I initially thought that it might be useful, but I've removed it because space
in this word isn't free.

 
 // Returns true if the specified cert status has an error set.
 static inline bool IsCertStatusError(CertStatus status) {
   return (CERT_STATUS_ALL_ERRORS & status) != 0;
 }
 
 // IsCertStatusMinorError returns true iff |cert_status| indicates a condition
 // that should typically be ignored by automated requests. (i.e. a revocation
 // check failure.)
 NET_EXPORT bool IsCertStatusMinorError(CertStatus cert_status);
 
 // Maps a network error code to the equivalent certificate status flag.  If
 // the error code is not a certificate error, it is mapped to 0.
 CertStatus MapNetErrorToCertStatus(int error);
 
 // Maps the most serious certificate error in the certificate status flags
 // to the equivalent network error code.
 NET_EXPORT int MapCertStatusToNetError(CertStatus cert_status);
