RFR 8044085: Access ExtendedGSSContext.inquireSecContext() result through SASL

[Wang Weijun]

Hi All

Please review the code change at

   http://cr.openjdk.java.net/~weijun/8044085/webrev.00

With this change, all existing (and future) InquireType values for ExtendedGSSContext.inquireSecContext() are available to the SASL GSSAPI mechanism as negotiated properties.

Code change is in GssKrb5Base.java. Clarification in spec of getNegotiatedProperty() in SaslClient and SaslServer. New lines in an existing test for sanity check.

Thanks
Max
