Mårten Kongstad 57f4b77c89 Runtime resource overlay, iteration 1.
Runtime resource overlay allows unmodified applications to appear
as if they had been compiled with additional resources defined. See
libs/utils/README for more information.

This commit is the first iteration of runtime resource overlay. It
provides the actual overlay modifications and loading of trusted overlay
packages (ie residing in /vendor) targeting framework-res.apk.

This commit loads exactly one overlay package. The overlay,
if present, must target framework-res.apk and be located at
/vendor/overlay/framework/framework-res.apk.

Unit tests for runtime resource overlay
=======================================

As of this writing, runtime resource overlay is only triggered for
/system/framework/framework-res.apk. Because of this, installation of
overlay packages require the Android platform be rebooted. However, the
regular unit tests (triggered via development/testrunner/runtest.py)
cannot handle reboots. As a workaround, this directory contains a shell
script which will trigger the tests in a non-standard way.

Once runtime resource overlay may be applied to applications, the tests
in this directory should be moved to core/tests/coretests. Also, by
applying runtime resource overlay to a dedicated test application, the
test cases would not need to assume default values for non-overlaid
resources.
