Webrev for 8043342: StringBuffer/StringBuilder crypto changes.

[Bradford Wetmore]

No additional code review necessary, this is just an FYI.

For internal reasons (i.e. we have to sign our JCE jar files), we have 
separated the JCE portion for:

8041679: Replace uses of StringBuffer with StringBuilder within the JDK

into:

8043342: Replace uses of StringBuffer with StringBuilder within crypto code

It's the exact same code, but only the four JCE files are included here.

I am sponsoring this for Jamil, from an original fix [1] sponsored by 
Paul Sandoz from:

Otávio Gonçalves de Santana

Thanks,

Brad
