...ActivityManagerService.updateLruProcessInternalLocked on bluetooth
Don't try to move process records associated with dead service
connections.
Technically we should probably be clearing the binding/service's
app entry so we don't get into this case, but the least intrusive
change for now is this check.

Changed public constants from integers to strings. Internally
everything is still integers, since we want that more efficient
representation for most things.
Changed the Callback interface to OnOpChangedListener. We also
have a private versin that again takes an int, and tricks to
make both work.
Reworked the class documentation to be appropriate to the SDK
(as much as it can be); most of the existing documentation is
moved to the private implementation. Also added documentation
of the MODE constants.

TLDR: Having a resumed activity behind keyguard can cause the keyguard
not to be dismissed.
Swiping the home button to launch Google Now causes an ASSIST intent
to be launched. The ASSIST intent starts SearchActivity which then
launches GEL. If an activity is resumed behind the keyguard when this
happens then that activity will be paused.
Because that activity is PAUSING, ActivityStackSupervisor
startActivityLocked() doesn't call dismissKeyguard() immediately.
Instead dismissKeyguard will be called later when GEL switches from
not-visible to visible. However, if the paused activity happens to be
GEL then there is never a not-visible to visible transition and
dismissKeyguard never gets called.
This fix removes an unnecessary call to resumeTopActivitiesLocked
which was causing activities behind the lockscreen to be resumed.
This fixes bug 10732489 except immediately after boot. Pausing the
initial activity if the lockscreen is visible after boot is deferred
for another CL.

...in ActivityManagerService.updateLruProcessInternalLocked on bluetooth
Add more debug output to help track down what is going on.
Also fix a little problem where, when a service ANRs, if you ask to
wait and it still wasn't responding, the ANR dialog wouldn't be
shown again.

Gah I messed up when refactoring so it would always be told
RAM is low.
Also slightly tune the low memory parameters to go into low
memory states a bit more aggressively.

The user has to explicitly enable a print service from the settings UI
before using it. Usually, users very rarely if at all interact with print
services, therefore all print service management task are performed from
the print settings. We also have to get user consent warning that the
user's data is about to be given to a third-party app. We now post a
notification allowing the user to go directly to the settings screen to
turn the service on.

Apps without sdcard_r or sdcard_rw are still able to write to
their package-specific directory, but someone needs to first make
that directory on their behalf. This change will delegate the
mkdirs() call through to vold when an app fails to create directly.
MountService validates that the path belongs to the calling user, and
that it's actually on external storage, before passing to vold.
Update Environment to make app-vs-vold paths clearer.

Moving a task to the bottom was also moving its stack to the back.
Since chrome always finishes by calling moveTaskToBack this put
the home stack in front of the application stack and would cause
bizarre window layering effects.

When transitioning from activity-over-launcher to task-over-launcher
ensureActivitiesVisibleLocked() was too aggressive in showing the
launcher. If there were any non-fullscreen activities in a task that
sits over the launcher then the launcher would be shown.
This fix adds a test to make sure the launcher will only be shown if
the bottommost activity in such a task is non-fullscreen.
Fixes bug 10840919.

...be uncached and too large
When the device is in a low RAM state, when we go to pull a cached
process out to use for some background operation, we can now kill
the current process if we consider its size to be too large.
Note that the current implementation for killing processes is to
just use the same killUnneededProcessLocked() method that we already
have for other things like too many cached processes. This is a
little wrong here, though, because in this case we are at the
point where the caller is actually looking for a process to use.
This current code is not actually removing or cleaning up the
process, so we still need to return the now killed ProcessRecord
and let things fall out from there, which typically means the caller
trying to make an IPC on it and failing and falling into its "oh
no the process died unexpectedly" path. All code using this
*should* be able to handle this correctly, anyway, since processes
really can be killed at any time.
At some point we may to make this implementation cleaner, where it
actually tears down the process right in the call and returns a
null ProcessRecord. That is very dangerous however (we'd need to
go through all paths into this to make sure they are going to be
okay with process state changing on them like that), and I'm not
sure it is really worthwhile. This intention is that killing
processes like this is unusual, due to processes being too large,
and anyway as I wrote all of our incoming code paths must already
be able to handle the process being killed at this point and one
could argue this is just another way to excercise those code paths.
Really, the main negative to this is that we will often have spam
in the log with exceptions about processes dying unexpectedly.
If that is the only issue, we could just add some conditions to
quiet that up at in this case.
We don't want to compute the size of the process each time we try
to evaluate it here (it takes 10s or ms to do so), so there is now
a new field associated with the process to give us the last pss
size we computed for it while it was in the cached state.
To be able to have better cached pss data when we now need it, the
timing for computing process pss has been tuned to use a much
shorter delay for the situations when the process has first switch
into a new state. This may result in us having a fair amount more
pss data overall, which is good, as long as it doesn't cause us to
be computing pss excessively and burning cpu.
Procstats now also has new state to keep track of the number of
times each process has been killed by this new system, along with
the min, avg, max pss of all the times it has happened. This has
slightly changed the checkin format to include this additional data
at the end of pkgkills/prockills lines.
Other changes here:
- Fixed a problem where GPU RAM was not being seen when dumping
the full RAM details of a process. This was because in that
case the system would ask the process to compute its own MemInfo,
which it returned, but the process doesn't have permission to
access the files containing the GPU RAM data. So now the system
always computes the MemInfo and hands it to the app.
- Improved broadcast delays to not apply the delay if the next receiver
of the broadcast is going to run in the same process as the last
one. A situation I was seeing was an application that had two
receivers, one of which started a service; we are better off letting
the second receiver run while the service is running.
- Changed the alarm manager's TIME_TICK broadcast to be a foreground
broadcast. This really should have been anyway (it is supposed to
go out even minute, on the minute, very accurately, for UI elements
to update), and is even more important now that we are doing more
things to delay background broadcasts.
- Reworked how we maintain the LRU process list. It is now divided
into the two parts, the top always containing the processes holding
activities. This better matches the semantics we want (always try
to keep those around modulated by the LRU order we interleave with
other cached processes), and we now know whether a process is being
moved on the LRU list because of an activity operation so we can
only change the order of these activity processes when user operations
happen. Further, this just makes that common code path a lot simpler
and gets rid of all the old complexity that doesn't make sense any
more.

At some point during refactoring of ActivityStack, the code to pause the current
activity got deleted. Added back that line of code. Activity will now pause
as soon as the screen is turned off, rather than after 5 seconds (sleep timeout).

Some services do periodic network time lookups and can wedge the other operations on
BackgroundThread and IO Thread, causing Watchdog to kill the runtime. So best to put
those handlers on separate threads.
Going forward, should convert NTP lookups to be async with callbacks.
