RFR 8056174: New APIs for jar signing

[Wang Weijun]

Hi All

An updated webrev is available at

  http://cr.openjdk.java.net/~weijun/8056174/webrev.06/

Compared with webrev.05, these changes are made:

1. In AlgorithmId.java, getDefaultSigAlgForKey() looks at the key size and returns signature algorithms with different digest part. Thanks, Mike!

2. In JarSigner.java: 

 - method names are longer, sigAlg() is now signatureAlgorithm(). Thanks, Mandy!

 - a new eventHandler() setter, so caller can show the progress of signing

 - value in setProperty(key, value) is only String now. No need to care about cloning

The change in the root idk repo is still
