Fix comments that refer to <overlay-config-signature> as
<config-signature>.

Remove malloc/free of android::ResTable_entry for inline overlay
values.
Add `target_entry_inline` to the idmap format to encode inline overlay
values separate from direct mapping of target resource to overlay
resource. This reduces the number of bytes needed to represent a direct
mapping of target resource to overlay resource from 9 bytes to 8 bytes
per entry.
Fixed all idmap alignment issues that required the framework to use
"#pragma pack(push, 1)" when loading idmaps.

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.

If the fulfilled policies change without the contents of the target
and overlay APKs changing, the idmap for the overlay should be
regenerated. This change adds fulfilled policies and enforce
overlayable to the idmap header so that idmap2d can determine if the
polices or enforce overlayable changed from what was used to generate
the idmap.

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.

android:resourcesMap is not working at all with shared libraries.
This change fixes that so overlays built as shared libraries can
use the attribute.

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.

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.

Change-Id: Ib94684a3b4001240321801e21af8e132fbcf6609
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.

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.
