Avoid unnecessary cache sloshing by placing the buffer size estimation update logic behind an atomic bit flag. The size of GSS information included in each wrapped Reply does not change during the lifetime of a GSS context. Therefore, the au_rslack and au_ralign fields need to be updated only once after establishing a fresh GSS credential. Thus a slack size update must occur after a cred is created, duplicated, renewed, or expires. I'm not sure I have this exactly right. A trace point is introduced to track updates to these variables to enable troubleshooting the problem if I missed a spot.
