RFR: JDK-6782021: It is not possible to read local computer certificates with the SunMSCAPI provider [v5]

[Mat Carter]

> On Windows you can now access the local machine keystores using the strings "Windows-MY-LOCALMACHINE" and "Windows-ROOT-LOCALMACHINE"; note the application requires admin privileges.
> 
> "Windows-MY" and "Windows-ROOT" remain unchanged, however given these original keystore strings mapped to the current user, I added "Windows-MY-CURRENTUSER" and "Windows-ROOT-CURRENTUSER" so that a developer can explicitly specify the current user location. These two new strings simply map to the original two strings, i.e. no duplication of code paths etc
> 
> No new tests added, keystore functionality and API remains unchanged, the local machine keystore types would require the tests to run in admin mode
> 
> Tested on windows, passes tier1 and tier2 tests
