b0643302c7 Enable obfuscation of resource names, with whitelisting support.
Test: Built aapt2, ran optimize on gmail apk with sample whitelist
config file, and flags enabled. Added two unit tests to TableFlattener
covering obfuscation logic.

490595a5fc AAPT2: Workaround for feature splits without namespacing
Android Instant Apps in its current iteration does not use namespaces,
but due to limitations on the Android resource runtime, needs to make
it look like it does.

This is due to a bug that treats any package ID that's not 0x01 or 0x7F
as a shared library. Shared libraries require unique package names.

As a workaround, and since Android Instant Apps can not have a feature
depend on another feature, we can alter the resource package name of a
feature split just before writing it out to disk. This avoids using a
unique package name while linking, thereby avoiding namespace issues.

This command allows a developer to convert their proto APK
(generated from the link phase using --proto-format) into
a binary APK suitable for use on device.

  phase.

0045116606 AAPT2: Define and Implement AAPT Container Format
AAPT Container Format (.apc) is a simple container that
enumerates the various intermediate files that AAPT2 generates
during the compile phase.

The format is defined in formats.md.

For now, continue using the .flat extension for the container file,
and keep making use of the .flata zip for storing multiple files.
This will allow easier integration with existing build systems and allow
the evolution of the APC format to better handle arbitrarily large
files.

ea13c1a234 AAPT2: Flatten AndroidManifest.xml stringpool in UTF16
A few OEM devices have introduced a memory corruption bug
that is only triggered when an application's AndroidManifest.xml
uses UTF8 string pools. Workaround this by only encoding
AndroidManifest.xml with UTF16 strings.
