b4e1249493 Add new ActivityManager.isLowRamDevice().
This and the old isHighEndGfx() is set up through a
device configuration, rather than trying to compute it
automatically.

13ac041b9f Update procstats to start collecting/reporting pss.
Completely reworked how it manages its data, since trying
to keep track of all of the possible pss data with the old
data structures would have made it huge.  Now we have a sparse
data structure for pss and process times.  (Will switch service
times over to it soon.)

Currently the only thing that collects pss data is running
"dumpsys meminfo".  More will be added later.

Modified checkin output to also scale better as more distinct
data categories are added, and added output of pss data.  Now
instead of dumping every possible entry as a comma-separated
list, it dumps a comma-separated list of only the entries with
data, tagged with the state they go with.

Also fixed some problems in the checkin reporting of batterystats
(it needs to escape commas), added checkin reporting of the history
list, fixed parsing of kernel wake locks to strip quotes, fixed
wake lock name that the sync manager generates to be more sane.

a17c0f5e16 More procstats work: separate global proc account, more dumping.
We now keep track of the time actually process run independently
of the time packages run in process, so we can give an accurate
summary of how long each physical process runs.

New command line options can be supplied to restrict printing to
a specific package, dump in a new csv format, control what is
printed in the csv format, and print a checkin report.

Add toString methods to ArrayMap and ArraySet.

91268cf21e More work on process tracking.
Re-arranged code to be more flexible, now track
state of services, dump ordered list of running
processes while memory was critical and low.

Also rename battery stats service from "batteryinfo" to "batterystats".

78a369c90f Improve process tracking.
We now keep track of when each process is running, batched
by the current memory status of the device.  In addition,
the stats are organized by package first, and then processes
associated with each package inside of that.  Finally, we
also keep track of the overall time spent in each memory
status.

This should start to actually get us to some information
we can reach some conclusions about.  The total time spent
in each memory status gives us some indication of how much
we are running while memory is low; the new package organization
batched by memory status lets us see what packages have
what processes running when memory is low.

be4e6aaa02 Initial super-primitive process tracker.
The goal of this is to keep track of what app processes
are doing, to determine who is being abusive, when the system
is getting into memory constrained situations, and help the
user determine how to resolve this.

Right now it doesn't really do any of that, just keeps track
of how long every process has been running since boot.

Also update the activity manager to use "cached" as the terminology
for what it used to interchangeably call hidden and background
processes, and switch ProcessMap over to using ArrayMap.
