- New Activity.reportFullyDrawn() method that applicatins can call
when they know they are fully drawn, allowing us to have better
app launch time info. This data is also included in usage stats.
- Added total and free memory data "dumpsys meminfo".
- Tuned the moderate memory levels to be more aggressive about
considering the device getting low on RAM, and thus starting
to prune RAM from processes.
- Fixed issues in processstats when reading old data as well as
resetting and other various fixes.

We now persistent the current procstats to storage
to keep them across boots. Still need to do division
and pruning across days; right now they will just keep
collecting forever.
Also fix some bugs in the checkin output.

Because the DisplayAdjustment in Display can be modified it should not
use the reference of the DisplayAdjustment that is passed in to
construct the Display. Copy the members of the DisplayAdjustment
instead.

The activity manager now uses some heuristics to try to
sample PSS data from processes so that it can get enough
data to over reasonable time have something useful, without
doing it too aggressively.
The current policy is:
1. Whenever a significant global change happens (memory state,
sceen on or off), we collect PSS from all processes; this will
not happen more than every 10 minutes.
2. When all activities become idle, we will collect PSS from the
current top process; this will not happen more than every 2
minutes per process.
3. We will sample the top-most process's PSS every 5 minutes.
4. When an process's oom adj changes and it has been more than
30 minutes since PSS has been collected from it, we will
collect a new PSS sample.
5. If a process changes from service A to service B (meaning it
has been running a service for a long time), we will collect
a PSS sample from it.
6. If someone explicitly requests PSS data (for running services
UI or dumpsys), record that.
Also:
- Finish moving the procstats output all to the new format.
- Record information about processes being killed due to excessive
wake locks or CPU use in procstats.
- Rework how we structure common vs. per-package process stats to
make it simpler to deal with.
- Optimize the Debug.getPss() implementation (we use it a lot now).
Should probably optimize it further at some point.

Removes onWakeKey/Motion handling from keyguard since it's no longer used.
The legacy code was originally intended to have keyguard filter wake events
which is now done in PhoneWindowManager. Ultimately it just needs to call
PowerManager.wakeUp() since keyguard no longer filters these keys.

Bug #9425270
When a TextureView is detached from its window and immediately
re-attached, the display list is not destroyed but reused as is.
TextureView will however destroy the layer and surface texture
reference by the display list.
The solution is to force TextureView to invalidate its display
list on re-attach if it previously had a surface/layer pair.

I made the power manager more rigid, not allowing different uids
to use the same wake lock. This never should happen. I would
guess there is somewhere that the activity manager is acquiring
the wake lock without clearing the calling identity... but it is
hard to follow all the paths this may happen in. So here we add
some checks when acquiring/releasing the wake lock to make sure
it is being done as the system uid.
Also:
- Protect the new activity stack calls with a permission, and
make sure to clear the calling uid once past that.
- Collect uid data from process stats so we can correctly
associate CPU use with a uid even if we don't know about the
pid for some reason.
- Fix battery stats dump commands to clear calling uid before
executing so they aren't broken.
