Change how we do debug dumps from the activity manager to make everything go through the activity manager interface (no more secondary interfaces), and use the command line arguments to control what gets dumped. The output from dumpsys without args still dumps everything. When just dumping the activity service, we now dump a subset of all of the am state that is interesting without being overwhelming. You can use "dumpsys activity -h" to get help with other things that can be dumped.
