Overlays targeting shared libraries should be loaded into the
resources of every target that depends on the shared library.
Static shared libraries are currently not supported because overlays
should override all versions of static shared libraries and there is
not currently support for an overlay targeting multiple APKs.
Also created a test instrumentation and host test suite for testing
overlays and packages on the system image.

When a shared library package is loaded into an AssetManager, the
shared library will be assigned a unique package id. Subsequent
AssetManaagers that load a shared library of the same package name
as the original shared library will use previously assigned package
name. Shared libraries will have stable package ids throughout the
lifetime of application.

Add a new variable length string to the idmap file format. This string will
hold debug information like fulfilled policies and any warnings triggered while
generating the file.
Bump the idmap version to 3.
Adjust the idmap header definition in ResourceType.h to take the new string
into account.

Also, tell cpplint to accept non-const references as function parameters:
they make more sense as out-parameters than pointers that are assumed to
be non-null.
Also, switch to regular expressions in the RawPrintVisitorTests: no more
manual fixups of the stream offsets! Tell cpplint that the <regex>
header is OK to use.

DisplayEventDispatcher will live in libgui for now, as a shim over
DisplayEventReceiver. This is so that we can keep libgui out of the
UI-renderer module while we can work on stabilizing the interface with
libandroidfw for asset management required by graphics classes.
It also doesn't make much sense to have display-event functionality in a
separate grab-bag library, especially when there's two users, and
there is potentially an opportunity to somehow merge with
DisplayEventReceiver to simplify code a bit.

Validates that the caller of an OverlayManager API that mutates state
is actually allowed to act on the target as defined in the target's
overlayable tag.
<overlayable name="MyResources" actor="namespace/name">
An actor is valid if any of the following is true:
- is root/system
- is the target overlay package
- has the CHANGE_OVERLAY_PACKAGES permission and an actor is not defined
- is the same package name as the sole resolved Activity for the actor specified
in the overlayable definition, with only pre-installed, namespaced actors
currently supported

Now that RROs are loaded as shared libraries,
LoadedApk#makeApplication is attempting to find the onResourcesLoaded
method of the overlays. This is a performance hit and causes more
memory than necessary to be allocated during application start up.

This change allows RROs to reference their own internal resources as
expected.
Overlays are loaded as shared libraries so they can have their own
resource id space that does not conflict with the resource id space of
the target or other overlays.
References to overlay resources that override target resources now
appear as references to the target resources.
Overlay values that are inlined into the xml file specified using
android:overlayResources are now able to be used at runtime.
See go/rro-references for more information.

This change modifies the idmap file format to allow for target resources
to map to arbitrary type/value combinations and to allow overlay
resources to be mapped back to target resource ids so references to
overlay resources can appear as references to target resources at
runtime.
The mappings of target resources to overlay resources and vice-versa are
both encoded as sparse arrays. Instead of looking up a resource by
indexing into an array that maps to the overlay resource id, the runtime
will binary search over the sparse array to find the type and value that
overlays the target resource.

ResourceLoaders allow inserting another .apk/.arsc into AssetManager's
resource resolution search. The effect is similar to overlays,
where a entry of >= config later in the path list will return that
ApkAsset's resource value instead.
Because loading from an .arsc is supported, which doesn't contain
any actual files, ResourceLoader exposes loadDrawable and
loadXmlResourceParser to allow an application load those files from
anywhere or create them in code.
The data being loaded is either pushed into an .apk or .arsc that
mocks itself as the package being "overlaid" and is passed in
through ResourcesProvider, an interface with static methods that
supports loading from a readable path on disk or a FileDescriptor.
The APIs are accessed through a Context's getResources(), which
has been changed to be unique per "Context-scope", which is usually
the lifetime of the Java object. The exception is that Activities
who get their Resources object persisted across recreations
maintain that logic for persisting ResourceLoaders.

This change introduces idmap parsing of <overlay> tags.
The <overlay> tag allows one to explicitly map resources in the target
to either a resource in the overlay or an inline attribute value.
Use the android:resourcesMap atttribute on the <overlay> tag in the
android manifest to specify a file to provide the resource mapping.
