Various infrastructure to support a running services UI.
Some of this is temporary (in particular the two approaches for getting
process memory, one working but horrible, the other not working but
preferred) until I figure out the best way to do it.

Various tweaks to try to improve low memory behavior.
- Reduce the amount that we ask processes to GC after a significant
operation occurs, but introducing a minimum time between GCs and
using this in various ways to schedule them.
- Don't spam all of the processes with onLowMemory(). Now deliver
these using the same gc facility, so we do the processes one at a
time, and don't allow the same process to get this call more than
once a minute.
- Increase the time a service must run before we will reset its
restart delay to 30 minutes (from 10).
- Increase the restart delay multiplication factor from 2 to 4.
- Ensure that we don't restart more than one service every 10 seconds
(unless some external event causes a service's process to be started
for some other reason of course).
- Increase the amount of time that a service must run before we
decide to lower it to a background process.
And some other things:
- Catch IllegalArgumentException in ViewRoot like we do for no
resources to avoid the system process crashing.
- Fix a number of places where we were missing breaks between the
activity manager's message dispatch func(!!).
- Fix reason printed for processes in the background.
- Print the list of processing waiting to GC.

Add more control over a service's start state.
One of the problems I have been noticing is background services
sitting around running and using resources. Some times this is
due to the app developer doing this when they shouldn't, but there
are also a number of issues with the current Service interaction
model that make it very difficult (or impossible) to avoid
getting services stuck in the started state. This is a
change/enhancement to the Service API to try to address this.
The main change is that Service.onStart() has been deprecated,
replaced with a new Service.onStartCommand() that allows the
service to better control how the system should manage it. The
key part here is a new result code returned by the function, telling
the system what it should do with the service afterwards:
- START_STICKY is basically the same as the previous behavior,
where we usually leave the service running. The only difference
is that it if it gets restarted because its process is killed,
onStartCommand() will be called on the new service with a null
Intent instead of not being called at all.
- START_NOT_STICKY says that, upon returning to the system, if
its process is killed with no remaining start commands to
deliver, then the service will be stopped instead of restarted.
This makes a lot more sense for services that are intended to
only run while executing commands sent to them.
- START_REDELIVER_INTENT is like START_NOT_STICKY, except if
the service's process is killed before it calls stopSelf()
for a given intent, that intent will be re-delivered to it
until it completes (unless after 4 or more tries it still
can't complete, at which point we give up).

invoke sendMessage instead of dispatchMessage to avoid deadlocks in ActivityManagerService
This API is becoming seriously abused, so now it is deprecated and has
become a no-op.
As an alternative, there is now a new API that allows you to make a service
be in the foreground but requires providing a persistent notification to
go along with this state, allowing the user to know about and control it.

Remove dead locks in system process when installing packages
This adds some new debugging code to make it easier to see why a process is at
a certain oom_adj level -- for example telling you that a certain other process
has a binding to a certain one of its services. This has helped a lot in
identifying cases where processes are holding references to other processes that
they don't need and thus not allowing the system to get memory it needs.
Also fix a few problems with leaking entries on the service restarting and
service stopping lists.
Re-arrange various things to ensure that the search dialog is told about system windows being
closed before it is told about the navigation back to home.
Create a new package setting object for updated system apps rather than moving
around the same setting. This updates the resource, code and version correctly.
For updating system packages, disable the package first which removes the entry
from internal structures, create a new package setting, add it to list of user id's
then rest of installation steps, kill the process if needed via ActivityManager
then add this setting if everything was successful. This also fixes issues with
updating values prematurely.
When a new version of system package is available via OTA, just physically remove
entries for pkg. Note that the component and other info will be eventually updated
later on when scanning the package.
Also move certificate verification slightly ahead before scanning packages.
Some null checks
New api's in ActivityManager to kill an application pkg before finishing installation
This was previously hard-coded to 0. Now set to the value of the
"ro.opengles.version" system property. The default value is
ConfigurationInfo.GL_ES_VERSION_UNDEFINED.

Issue #1969025: need api for launching intent as if it were coming from another component
This adds a new API with the activity manager to find out about movement between
activities. For my sanity, the old IActivityWatcher is now renamed to
IActivityController, and the new activity movement interface is named
IActivityWatcher.
This changes the search manager itself to use the new API to manage its state.
Note that there are still problems when going back to the search dialog after
it was hidden -- the suggestions window no longer appears until you explicitly
dismiss and re-show it.
This is the problem where various things are listening for broadcasts
(such as battery status, PIN/PUK/Network) that an application can send
to cause harm to the system.
Solving this is tricky because many of these broadcasts are sticky,
and I have never figured out how to do permissions with sticky
broadcasts in a sane way. So instead, I am going to punt on the
general problem and just brute force it:
There is new a way for system components to declare specific
broadcast actions to be protected, which means that only the system
and the phone can send them. This is good enough for now. None
of it is exposed in the public API so we can make something a little
less stupid in the future if we ever need to.
This adds a new <path-permission> tag you can use inside of a <provide>
to define additional path-based permissions that broaden the global
read and write permissions. The initial use for this will be global
search, so that a content provider that is protected by permissions
can make a part of itself available to global search under another
permission. This addresses the issue with global search not being able
to request permissions it would need of providers it doesn't know
about at build time.
