Review request: 8003562: Provide a command-line tool to find static dependencies

[Mandy Chung]

This is the updated webrev. It includes Erik's makefile changes and
small change - be consistent with javap, jdeps can take classnames as
the input argument or wildcard "*" to analyze all class files that
replaces the "-all" option.
