We also now ignore attempts to set preferred resolutions with
intent filters for which no actions are defined.

We need to be able to perform very lengthy operations on some threads
(e.g. the I/O thread responsible for installing multi-gigabyte APKs) but
still have long-run deadlock/hang detection applied to those threads.
Previously the watchdog mechanism applied the same policy to all
monitored threads: unresponsive after 60 seconds => restart the system.
Now, each monitored entity can have its own independent timeout after
which the watchdog declares deadlock and restarts the runtime. The
halfway-finished intermediate thread stacks are dumped based on the
specific entity's declared timeout, not the global 30 second checking
interval.
With that new mechanism in place, the Package Manager's lengthy-I/O
thread watchdog timeout is raised to 10 minutes.

Because properly continuing permission grants post-OTA has changed
policy to include privilege considerations based on install location,
make sure that we re-evaluate when we determine that the apk has
moved from its pre-OTA location.

In this case:
1. Privileged system app FOO is overlain by an installed update,
2. FOO was replaced during an OTA,
3. The new in-system FOO introduced new privileged permission requests
that had not been requested by the original FOO,
4. the update version of FOO still had a higher version code than
the new FOO on the system disk, and
5. the update version of FOO had been requesting these same (newly-
added-to-system-apk) permissions all along;
then the newly-added privileged permission requests were incorrectly being
refused. FOO should be able to use any privileged permission used by the
APK sited on the system disk; but instead, it was only being granted the
permissions used by the *original* version of FOO, even though the system
FOO now attempted to use them.
Still with me?
The fix is to (a) properly track privileged-install state when processing
known-to-be-hidden system packages, and (b) to tie the semantics of the
permission grant more explicitly to that evaluated state, rather than
using the prior (rather fragile) fixed-up privilege calculation applied
to the overlain apk's parse records.

When an apk is installed on ordinary unmountable media, a broadcast
is sent when the OS wants to unmount it so that interested parties
can cleanly close any files they have open to read that apk's
resources or similar. We now send that broadcast when we are
about to unmount the ASEC fs container that holds a forward-locked
apk as well, so that e.g. Home knows to release the resources that
it was using for widget hosting or similar.

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.

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.

This is an extension from the existing data/etc/perferred-apps
facility. Now applications pre-installed on the system image
can declare which intents they would like to be considered the
preferred app for. When the system firsts initializes, or the
application settings are reset, these are used to configured
the current preferred app settings appropriately.
You use this with a new <preferred> tag under your activity,
which indicates which intents you would like to be the preferred
handler for. The syntax for this is written much like an
intent filter, however semantically it is not really an intent
filter and so has some important differences:
- You can not use globbing patterns (for SSPs or paths).
- You can use only one action (if you use more than one it
will only use the first one, so be careful).
Semantically what this is actually used for is a template
from which to generate a set of Intent objects, which are used
to probe the current environment in order to see if there are
multiple activities that can handle the Intent and, if so,
generate a new preferred setting for that pointing to your app.
As an example, here is how the preferred tag might be written
for the Maps application:
<preferred>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" />
<data android:scheme="https" />
<data android:host="maps.google.com" />
<data android:path="/" />
<data android:pathPrefix="/maps" />
</preferred>
<preferred>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="geo" />
</preferred>
From this, we generate the following set of potential Intents
to be matched, all with ACTION_VIEW, CATEGORY_DEFAULT+CATEGORY_BROWSABLE:
