Adds a command line option `-redact` to `jcmd`, `redact` to `jmap` and `-XX:+HeapDumpRedacted` enabling redacted heap dumps. When enabled, the output binary heap dump has zeroes written out in place of the original primitive values in the object fields. There is a new jtreg test `heapDumpRedactedTest.java` that tests that the fields are properly redacted.
