RFR 8076190: Support passwordless access to PKCS12 keystores

[Weijun Wang]

Webrev updated at

   http://cr.openjdk.java.net/~weijun/8076190/webrev.02

The only change is in keytool/Main and the test. keytool will not prompt for store password if it detects a password-less keystore.

This is 3) below.

Thanks
