The purpose here is to provide support for selectively
enabling Runtime Resource Overlays (RROs) (specifically
those pertaining to a specific SKU, within a OEM's "single
build" covering multiple SKUs) at boot based on the value
of a pre-defined system property.
This mechanism is designed to be compatible with other,
recent changes to Runtime Resource Overlays - specifically:
- has no effect on 'isStatic'. Resource overlays must be
attributed as static in order to qualify for loading into
the system_server. The 'requiredSystemPropertyName/
requiredSystemPropertyValue' mechanism operates
independent of this and can be used on both static and
non static overlays. The effect of specifying a conditional
property on any overlay is that it will ONLY be enabled
in the event that the system reflects both the property
and the specified value (Note that in the ABSENCE of a
conditional property, overlays are assumed to be enabled).
- has no effect on OverlayManagerService (OMS) API. The
OMS provides the system with an interface through which
overlays can be enabled/disabled and even rearranged at
runtime. This provides the basis of support for various
user-level features (e.g. dynamic theme selection).
The 'requiredSystemPropertyName/requiredSystemPropertyValue'
mechanism operates independent of this -
with enablement being completely coupled to the available
system properties on the device and NOT subject to change
at runtime.
Note: as part of this change, original overlay tests have been
updated (fixed) and expanded to include tests to cover the
conditional property implementation.

(cherry picked from commit d5566c6c47faa6b9dda282741e25ac78c9487d58)
Static RRO package is designed to support resource overlay for system
server and they shouldn't be disabled or changed by a user.
The design details are in go/treble-static-rro.
Selection method for static RROs will be applied later when its design
is determined.
Test: building succeeded and tested on sailfish.

Hand over ownership of overlays to OverlayManagerService.
Changes to a package's overlays are propagated using the activity life
cycle. Affected activities will be recreated as needed. This provides a
well-defined point to modify an application's assets while the
application is paused.
Consolidate how overlays targeting the system and overlays targeting
regular applications are handled. Previously, system overlays were
handled as a special case. Now, everything is handled identically. As a
side effect, the call to idmap --scan during Zygote boot has become
obsolete and is removed.
Information on what overlays to use is recorded in
ApplicationInfo.resourceDirs. The PackageManagerService is responsible
for the creation of ApplicationInfo objects. The OverlayManagerService
is responsible for informing the PackageManagerService in advance about
what resourceDirs to use.
When launching an application, the ApplicationInfo is already populated
with up-to-date information about overlays.
When enabling or disabling an overlay for a running application, the
OverlayManagerService first notifies the PackageManagerService about the
updated resourceDirs. It then tells the ActivityManagerService to push
the new ApplicationInfo object to the application's ActivityThread.
Finally the application requests its ResourcesManager to create new
ResourcesImpl objects based on the updated paths.

idmap --scan is executed as a part of the pre-loading in ZygoteInit.
The pre loading is executed in parallel for each supported architecture
(32/64 bit). This will cause a race condition in the creation of the
overlays.list file and the idmap files for the system overlays.
Apply flock on overlays.list to prevent the file from being thrown away
and recreated when it is in use by another Zygote.
Cherry-picked from AOSP.

Multiple overlay packages with targetPackage="android" are loaded in the
wrong order due to the incorrect order they are listed in overlays.list.
This will cause runtime resource overlay to fail when multiple overlay
packages target the same resources in framework-res.apk.
Correct the order in which overlays are loaded by changing the sorting
of overlays.list.
Background: commit f90f2f8d changed the order in which overlay packages
should be added to ResTables. The expected order is now in ascending
priority. This must be reflected in overlays.list.

The 'idmap --scan' command was limited to only scan a single directory
for overlay packages. Update idmap to support any number of directories.

getEntryInfo crashes on 64-bit devices because "long" types
were being passed int pointers (that pointed to a stack frame)
that were reinterpret_cast'ed to long* (sigh.). To fix this issue
once and for all, use types with explicitly defined widths.
This change also removes some dead invariant checking from
Asset.cpp instead of cleaning it up.
Note that we've introduced a wart in NativeLibraryHelper, where
we need to deal with zlib's uLong type, which is "at least 32 bits
wide".

scan.cpp gets sys/stat.h inherited from
private/android_filesystem_config.h it should
not rely on this in the future. The intent is
to move fs_config function into libcutils and
thus deprecate any need for sys/stat.h in this
include file.

Shared libraries can now export resources for applications
to use.
Exporting resources works the same way the framework exports
resources, by defining the public symbols in res/values/public.xml.
Building a shared library requires aapt to be invoked with the
--shared-lib option. Shared libraries will be assigned a package
ID of 0x00 at build-time. At runtime, all loaded shared libraries
will be assigned a new package ID.
Currently, shared libraries should not import other shared libraries,
as those dependencies will not be loaded at runtime.
At runtime, reflection is used to update the package ID of resource
symbols in the shared library's R class file. The package name of
the R class file is assumed to be the same as the shared library's
package name declared in its manifest. This will be customizable in
a future commit.
See /tests/SharedLibrary/ for examples of a shared library and its
client.
