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.

Change idmap to iterate over the resources in the overlay package
instead of the target package when scanning for resources defined in
both packages. This cuts down the runtime cost of creating an idmap
considerably since the algorithm now scales with the number of resources
in the overlay package (a handful) and not the number of resources in
the target package (android: 10k, SystemUI: 8k) at a minor cost to code
complexity.
Improvements on the runtime of ResTable::createIdmap (systrace on an
emulator running aosp_x86_64-eng):
- target=android: 12.5 ms -> 3.0 ms
- target=SystemUI: 8.6 ms -> 1.0 ms
The bulk of the cost of creating an idmap from installd is now the fork
and execl to call "idmap --fd ..." which weigh in at 16 ms.

The entry pool is encoded in UTF-8 not UTF-16. This would cause stringAt
to return a pointer to a cache that holds the UTF-8 string converted to
UTF-16. If the cache becomes invalidated, the UTF-16 pointer is no
longer valid and causes seg faults when looked up.

The docuemntation of setTo states that the resources two styles from
different AssetManagers have in common will be set in the destination
theme. This change adds this functionality. The package ids of the
attributes, the package ids of reference values, and the cookie of
attribute values have to be rewritten to match the destination
AssetManager. This change can later be made more generic if rewriting
references between packages is needed elsewhere.

AAPT would allow for ids to be declared in the form:
<item name="name" type="id>@id/other</item>
@id/name should hold a reference to @id/other. When
getResources().getValue() is called on R.id.name with resolveRefs
enabled, the resuling reference should be R.id.other.

AAPT incorrectly writes a truncated string length when the string size
exceeded the maximum possible encode length value (0x7FFF). To decode a
truncated length, this change iterates through length values that end
in the encode length bits. Strings that exceed the maximum encode length
are not placed into StringPools in AAPT2.

AssetManager2 assumes that RES_TABLE_TYPE_SPEC_TYPEs must immediately
precede their associated RES_TABLE_TYPE_TYPEs. This is not correct.
RES_TABLE_TYPE_SPEC_TYPEs must precede their associated
RES_TABLE_TYPE_TYPEs, but they do not need to immediately precede them.
For example, this is what we currently expect:
RES_TABLE_TYPE_SPEC_TYPE id=1
RES_TABLE_TYPE_TYPE id=1
RES_TABLE_TYPE_SPEC_TYPE id=2
RES_TABLE_TYPE_TYPE id=2
but this is also valid:
RES_TABLE_TYPE_SPEC_TYPE id=1
RES_TABLE_TYPE_SPEC_TYPE id=2
RES_TABLE_TYPE_TYPE id=1
RES_TABLE_TYPE_TYPE id=2

AssetManager2 relied on creating a list of configurations
present in the resource table so as to avoid copying and
converting ResTable_config's from the APK on every
resource retrieval.
ResTable, however, had a better optimization that pruned
the configurations that didn't match the currently set
configuration. This vastly reduced the number of ResTable_configs
to test.
In this CL, AssetManager2 follows suite with this optimization
and only maintains the filtered ResTable_configs, falling back
to the slow path when the configuration is overridden.

If the value passed to AssetManager::ResolveReference is not a
reference, the caller may be expecting for the last reference to
not be cleared, as a more appropriate value should most likely be
retained.
This was causing an issue when a caller was manually resolving
references and expecting the last resource ID resolved to be propagated
across calls to ResolveReference.
