dumpsys: dump multiple types of info in one run
I was looking at which processes were using too many threads, since
almost all services in dumpsys report 0/16 threads out of use, and this
looks like a lot of (potentially wasted threads). However, almost all of
these come from system_server, so they are actually shared among all of
the services. Though, from the existing output of dumpsys, it was a bit
hard to actually understand this without comparing two outputs.
This still isn't quite like lshal (which has columns), but at least now
I can run `dumpsys --thread --pid` and I can see all the services and
see their processes to make this analysis easier.
