When killing a task from the recents UI, the activities in
the task would be scheduled for destruction, and the task would
be forcefully removed from the ActivityStack, destroying the
ActivityStack in the process if this was the last task. Since the
ActivityStack was removed, any activities calling back to report
their onDestroy was called (or any timeouts that trigger if
activities fail to do this) would be dropped and certain cleanup
routines would not be called.
Tasks and their ActivityStacks are removed automatically when the
activities within them are removed, so this manual removal was
preventing the cleanup routines from running.

Reduce the number of recent tasks to 10 on lowram devices
Use RGB_565 on low ram devices for thumbnails instead of ARGB_8888
Combined this saves ~9MB across system_process and systemui

The main problem here was a mistake when turning a single process
structure to a multi-package-process structure with a common
process. When we cloned the original process state, if there were
any services already created for the process for that package, they
would be left with their process pointer still referencing the
original now common process instead of the package-specific process,
allowing the active counts to get bad. Now we switch any of those
processes over to the new package-specific process.
There was also another smaller issue with how ServiceRecord is
associated with a ServiceState -- we could be waiting for an
old ServiceRecord to be destroyed while at the same time creating
a new ServiceRecord for that same service class. These would share
the same ServiceState, so when the old record finally finished
destroying itself it would trample over whatever the new service
is doing.
This is fixed by changing the model to instead of using an "active"
reference count, we have an object identifying the current owner
of the ServiceState. Then when the old ServiceRecord is cleaning
up, we know if it is still the owner at that point.
Also some other small things along the way -- new Log.wtfStack()
method that is convenient, new suite of Slog.wtf methods, fixed
some services to use Slog.wtf when catching exceptions being
returned to the caller so that we actually know about them.

If two activities are started at the same time the first activity can
add a starting window but never start. In that case there is no event
that will clear the starting window. This change adds a 10 second
timeout for the starting window to be cleared after which it will
clear the starting window automatically.

All ContentProvider calls are currently blocking, making it hard for
an app to recover when a remote provider is wedged. This change adds
hidden support to ContentProviderClient to timeout remote calls,
treating them as ANRs. This behavior is disabled by default.
Update DocumentsUI to use a 20 second timeout whenever interacting
with a storage provider.

Not dealing with the case where there is a null list.
Also fixed some bugs I found while looking at this:
- When resetting the stats, we would use a newly computed time stamp
for the total durations rather than the one we used to reset the
proc/service entries. This would result in them being able to be
slightly > 100%.
- There was a bug in how we split a single process state into its
per-package representation, where we would but the cloned process
state into the new package's entry (instead of properly for its
own package entry), to be immediately overwritten by the new
process state we make for that package. This could result in
bad data for processes that have multiple packages.
- There was a bug in resetting service stats, where we wouldn't
update the overall run timestamp, allowing that time to sometimes
be > 100%.
- There was a bug in computing pss data for processes with multiple
packages, where the pss data was not distributed across all of the
activity per-package process states.
- There was a bug in computing the zram information that would cause
it to compute the wrong value, and then never be displayed.
Finally a little code refactoring so that ProcessState and ServiceState
can now share a common implementation for the table of duration values.

Now when memory low, if a service's process is above
a selected pss, then the process is not allowed to go
in to the service a list.
Also simplified the normal meminfo details dump to not
include the shared dirty and shared clean sizes by
default, since these can be very confusing. You will
still get to see them with the "-a" flag.
Finally some small steps to better managing service
processes in the LRU list, so hopefully we can some
day be better about letting them drop down in the list
when there isn't really much interesting happening in
the process. Not yet used at this point.

Change our Intent flag to indicate that a Uri permission grant is
persistable, but don't actually persist it until explicitly taken by
the receiving app. This prevents apps from spamming each other if
persisted permissions aren't really required.
Remember the last time a persisted grant was taken by an app, and
use this to prune away the oldest grants when the number of grants
grows too large. Allow apps to query persisted grants they are
holding, and allow them to release previously persisted grants. Add
public UriPermission class to return grant details and timestamp.
Track various permission strengths separately, and combine together
after each mutation pass. Persistable grants are currently treated
like global grants, but they could be moved to have owners in the
future. Require that grant holders trying to extend a persistable
permission actually hold a persistable permission themselves.

The problem was that the ResolverActivity filters some activities
out of the list it shows, but it uses that display list as the
list of components the preference is set against when ultimately
setting it on the package manager... but that filtered list is *not*
the right component set, since it is not the same as the package
manager's view on it.
The fix here is to retain the original set of matching components
and use that when setting the preferred activity. Note that this
does mean that in very unusual cases where filtering is happeing
(such as one of the activities not being exported but being seen
as a possible completion from another app), then you will be setting
the preference for the complete set. Ultimately we probably need
to have the package manager apply these filtering rules up-front so
this is all consistent, but this is a very rare case so not that
important.
And then most of the change here is just improving the debug
output for intent resolution.
