[10] RFR 8177085: Accept including .conf files in krb5.conf's includedir

[Weijun Wang]

Please review the code change at

    http://cr.openjdk.java.net/~weijun/8177085/webrev.00/

This is to be consistent with MIT krb5 [1]

  "Including a directory includes all files within the directory whose 
names consist solely of alphanumeric characters, dashes, or underscores. 
Starting in release 1.15, files with names ending in ”.conf” are also 
included."

New case added to test. Also some rename to make it clearer.

Thanks
Max
