For future macro support, aapt2 must be able to convert Reference
values into other Value types. Currently a DescendingValueVisitor is
used to visit all of the References in a ResourceTable or a compiled
XML file to set their resource ids during the link phase. This was fine
since we were only mutating the resource id of the visited Reference.
A macro may reference a String, BinaryPrimitive, or any other Item
type. During the link phase, we will need to transform references to
macros into the values of the macros.
The only parameter in the methods of the ValueVisitor interface is a
raw pointer to the type being visited. The visitor interface does not
support reassigning the visited type to a different type.
ValueTransformer is a new interface for consuming a Value type and
transforming it into a compatible Value type. This change refactors
Value::Clone to use this interface.

Migrate libandroifw to using incfs::util::map_ptr to prevent processes
from crashing when parsing the resources.arsc, parsing compiled xml,
files, and retrieving resource values.
This change propagates incremental failures to the JNI level where they
are raised as ResourcesNotFoundException.

Alongside SIGNATURE and ACTOR_SIGNATURE policies, add CONFIG_SIGNATURE
policy to overlayable that overlay fulfills if it is signed with the
same certificate as the reference package whose package name is
declared in 'config-signature' tag of SystemConfig and is vetted by
OMS that it's a system pre-installed package.

There are cases where an app can ship overlays for itself,
but the "signature" policy as described would open up
a vulnerability by allowing the system actor to create
and sign any arbitrary overlay that will apply to the target.
To prevent this, redefine "signature" as target package only,
and introduce "actor" for checking against the actor signature.
Any app that wishes to use both can include both policies.

To make it easier to add the actor policy in a follow up CL,
move most of the policy handling to a central location.
The strings and transformation between strings and flags is
now handled in libidmap2policies, with libandroidfw
containing the single source of policy flags.
This also extracts all the test resource IDs into an R.h
so they can be swapped without having to edit a dozen files
each time.

AssetManager2.cpp expects style attribute IDs to be in sorted order when
applying a style (see AssetManager2::GetBag). Shared libraries have a
package ID of 0x00, which will mean any attribute defined in a shared
library will be put before all other attributes. Once the attribute ID
is looked up in the dynamic ref table, the package ID is no longer 0x00,
which means this ID is no longer in sorted order. This messes up the
logic in AssetManager2::GetBag, and results in some style attributes
getting dropped from shared libraries.
This change modifies how aapt2 sorts the style entries, sorting entries
with dynamic IDs after entries with the android framework ID. This means
the entries will still be in sorted order when the IDs are looked up.

Removed the --whitelist-path flag, which is poorly named and we can
already specify these resources with --resources-config-path.
Renamed TableFlattenerOptions.whitelisted_resources to keep_resources.
It holds ResourceName instead of std::string. This lets us include type
when specifying what gets exempted, for correctness.

Add encoding/decoding of new policy for overlays. Signature enforces
that an overlay package is signed with the same key as the actor of
the target resource, so that an overlay can be installed by the user
as a normal app but restricted to those built by the author of the
actor (which can be the same as the target).
This also enforces that a valid policy is specified.
This doesn't implement the actors nor the signature check.

This change defines two new chunks for encoding overlayable information.
RES_TABLE_OVERLAYABLE_POLICY_TYPE contains flags that represent
restrictions enforced on overlays that try to overlay a specific set of
resource ids. The chunk header is followed by ResTable_ref for each id
that belongs to the policy type. A policy chunk will be created for
every unique combination of policies that are defined in overlayable
declarations.
RES_TABLE_OVERLAYABLE_TYPE holds policy blocks. Since <overlayable>
does not currently have any attributes, only one overlayable block is
encoded in an APK.
This change also removes the SPEC_OVERLAYABLE flag because the runtime
does not use the flag, and the overlayable chunk encoding renders it
obsolete.

<overlayable> tags can now have policy elements that indicate which
partition the overlay apk must reside on in order to be allowed to
overlay a resource. This change only adds parsing of <policy> and
encoding of policy in the proto ResourceTable. A later change will add
the encoding of policy and overlayable in the binary APK.

If a resource XML file defines two compatible Attributes, they should
be merged without throwing an error. Ex:
<declare-styleable>
<attr name="conflict" format="string" />
</declare-styleable>
<declare-styleable>
<attr name="conflict" format="string|reference" />
</declare-styleable>
In this case, string|reference and string are the same, so these should
merge correctly.

Resources can be marked as overlayable, which means they can
be overlaid by runtime resource overlays.
This change propagates this state to the final resource table that
is installed on device.
Future work:
- Have the idmap tool respect the overlayable state and ignore
entries that overlay anything else.
