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.

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.

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.

...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.

Add new intent flag to not allow receivers to abort broadcasts, which

We now have the activity manager kill long-running processes
during idle maintanence.
This involved adding some more information to the activity manager
about the current memory state, so that it could know if it really
should bother killing anything. While doing this, I also improved
how we determine when memory is getting low by better ignoring cases
where processes are going away for other reasons (such as now idle
maintenance). We now won't raise our memory state if either a process
is going away because we wanted it gone for another reason or the
total number of processes is not decreasing.
The idle maintanence killing also uses new per-process information
about whether the process has ever gone into the cached state since
the last idle maintenance, and the initial pss and current pss size
over its run time.

This significantly reworks the logging we do when
all cached processes are killed:
- We now collect the list of processes in-place so we
have a snapshot of exactly when the low memory situation
happened.
- In that snapshot we include the key process state: oom
adj, proc state, adj reasons.
- The report then asynchronously collects pss information
for those processes.
- The ultimate data printed to the log looks like a mix
between the "dumpsys meminfo" and "dumpsys activity"
output. This code no longer uses "dumpsys meminfo"
itself, so some of that data is no longer included,
in particular pss organized by allocation type.
In doing this, I realized that the existing code that is
supposed to run "procstats" is not currently working. And
at that point I realized, really, when we are collecting
this pss data we'd really like to include all those native
processes using ghod-only-knows how much RAM. And guess
what, we have a list of processes available in
ProcessCpuTracker.
So we now also collect and print information for native
processes, and we also do this for "dumpsys meminfo" which
really seems like a good thing when we are printing summaries
of all pss and such.
I also improved the code for reading /proc/meminfo to be
able to load all the interesting fields from there, and
am now printing that as well.

it does not try to operate on one of these structures when not in

Also some other fixes:
- We now keep track of process names associated with services, for

- Keep track of total run time for each service, also for UI.
- The parceled format is more efficient, not storing duplicates of
process/package names, and writing times as ints when possible.
- Reduced commit period from 1 day to 12 hours, so that our UI can
