5e03e2ca7d More multi-user stuff:
- New (hidden) isUserRunning() API.
- Maintain LRU list of visited users.
- New FLAG_IS_DATA_ONLY for ApplicationInfo.
- Clean up pending intent records when force-stopping a user (or package).
  (Also fixes bug #6880627: PendingIntent.getService() returns stale
  intent of force stopped app)
- Fix force-stopping when installing an app to do the force-stop across
  all users for that app.
- When selecting which processes to kill during a force stop, do this
  based on the actual packages loaded in the process, not just process
  name matching.
- You can now use --user option in am when starting activities, services,
  and instrumentation.
- The am --user option accepts "current" and "all" as arguments.
- The pm uninstall command now uninstalls for all users, so it matches
  the semantics of the install command.
- PhoneWindowManager now explicitly says to start home in the current
  user.
- Activity manager call to retrieve the MIME type from a content provider
  now takes a user argument, so it will direct this to the proper user.
- The package manager uninstall paths are now implemented around
  PackageSetting, not PackageParser.Package.  This allows them to work
  even if the application's apk has been removed (in which case it only
  exists as a PackageSetting, not the PackageParser.Package parsed from
  the apk).

4120375d46 Remove Binder.getOrigCallingUid().
Replaced all remaining places that used it with explicit user
specification.

While doing this, I ran into stuff that was creating PendingIntent
objects (that now need to specify the explicit user they are for),
which are also posting notifications...  but have no way to specify
the user for the notification.

So the notification manager in the system process now also gets a
formal concept of a user associated with the notification, which
is passed in to all the necessary aidl calls.  I also removed the
old deprecated aidl interface for posting/cancelling notifications,
since we now always need a user supplied.

There is more work that needs to be done here, though.  For example
I think we need to be able to specify USER_ALL for a notification that
should be shown to all users (such as low storage or low battery).
Along with that, the PendingIntent creation needs to be tweaked to
be able to handle USER_CURRENT by evaluating the user at the point the
pending intent is sent.

That's for another change, however.

This is the start of turning this into a formal public API.

8809004bc5 ProviderMap: remove hashmap when entire user specific entries are removed
User specific entries in  mProvidersByNamePerUser and mProvidersByClassPerUser
isn't cleared when entire user specific providers are removed. Fix is to remove
the user specific hashmap in such cases.

f88dd0b32e Small service cleanup.
Get rid of duplication between find/retrieve service funcs; when
a service in a persistent process crashes, restart it immediately
since the persistent process is going to be immediately restarted
anyway; when a new process is attaching, immediately restart any
services associated with it that are waiting to restart, since
it is weird to not let them run if the process comes back for some
other reason.

7d19e0242f More mult-user API work.
- You can now use android:singleUser with receivers and providers.
- New API to send ordered broadcasts as a user.
- New Process.myUserHandle() API.

For now I am trying out "user handle" as the name for the numbers
representing users.

6ae8d18218 Fix (mostly) issue #5109947: Race condition between retrieving a...
...content provider and updating its oom adj

This introduces the concept of an "unstable" reference on a content
provider.  When holding such a reference (and no normal stable ref),
the content provider dying will not cause the client process to be
killed.

This is used in ContentResolver.query(), .openAssetFileDescriptor(),
and .openTypedAssetFileDescriptor() to first access the provider
with an unstable reference, and if at the point of calling into the
provider we find it is dead then acquiring a new stable reference
and doing the operation again.  Thus if the provider process dies
at any point until we get the result back, our own process will not
be killed and we can safely retry the operation.

Arguably there is still the potential for a race -- if somehow the
provider is killed way late by the OOM killer after the query or
open has returned -- but this should now be *extremely* unlikely.
We also continue to have the issue with the other calls, but these
are much less critical, and the same model can't be used there (we
wouldn't want to execute two insert operations for example).

The implementation of this required some significant changes to the
underlying plumbing of content providers, now keeping track of the
two different reference counts, and managing them appropriately.  To
facilitate this, the activity manager now has a formal connection
object for a client reference on a content provider, which hands to
the application when opening the provider.

These changes have allowed a lot of the code to be cleaned up and
subtle issues closed.  For example, when a process is crashing, we
now have a much better idea of the state of content provider clients
(olding a stable ref, unstable ref, or waiting for it to launch), so
that we can correctly handle each of these.

The client side code is also a fair amount cleaner, though in the
future there is more than should be done.  In particular, the two
ProviderClientRecord and ProviderRefCount classes should be combined
into one, part of which is exposed to the ContentResolver internal
API as a reference on a content provider with methods for updating
reference counts and such.  Some day we'll do that.

9da2d40334 Fix swiping away recents to always kill processes.
This would only kill processes if there were activities associated
with the recent task; now it always kills processes.

Always fix some debug output.
