RFR: 8339280: jarsigner -verify performs cross-checking between CEN and LOC [v17]

[Hai-May Chao]

> The jarsigner -verify command currently performs verification by reading from JarFile to navigate the central directory (CEN) headers. It is now enhanced to include cross-validation of entries between JarFile (CEN-based) and JarInputStream (stream-based) representations of the JAR. It emits earnings when detecting discrepancies between a JAR file’s central directory and its local file entries.

Hai-May Chao has updated the pull request incrementally with one additional commit since the last revision:

  Not split warning in rb.getString() accross multi-lines for Usages.java
