2d34e76dac Add --trace_folder to aapt2
Add a tracing API and instrument key functions in order to profile
aapt2 bottleneck. The API allows to generate systrace fragment files.

Impact on performance is neglibible with each Trace requiring less
than 1us and the final Flush operation at the end of a command
requiring around 40us.

54237ffed4 Add actor and name parsing for overlayable
Add parsing of two overlayable attributes:
 name : The unnique identifying name of the overlayable set of resources
 actor: The component responsible for enabling and disabling overlays
        targeting the specified set of resources

1bb1fe068a Refactor policy parsing
This change removes the ability for an overlayable resource to be
defined in multiple policy blocks within the same overlayable. This
change also changes aapt2 to use a bit mask to keep track of the parsed
policies.

A resource marked SPEC_OVERLAYABLE in the base package was not marked as
such in the corresponding split packages. Add missing copy statement.

9fbdf89dda Don't allow splitting on an empty configuration
When aapt breaks out splits, it may remove the SDK constraint [if
it's lower than the min sdk]. If that is the only constraint, we
would create a resource split with no constraints. Don't allow
that situation. There must always be _some_ constraint.

71be70507d AAPT2: Propagate SPEC_OVERLAYABLE flag to final APK
Resources can be marked as overlayable, which means they can
be overlaid by runtime resource overlays.

This change propagates this state to the final resource table that
is installed on device.

Future work:
- Have the idmap tool respect the overlayable state and ignore
  entries that overlay anything else.

0a5b201156 AAPT2: Add a APK filtering.
Allow resource files to be removed from the final artifact based on the
density and locale configuration in the config file. The APK is split
along the density, locale and ABI axis. Each split is generated from the
original APK without modifying the original. The new resource table is
written back to the file system with unneeded assets etc removed.

Test: Unit tests
Test: Manually run optimize command against an APK and inspect results
Test: Installed split searchlite APK (after resigning) and ran on N6

libandroidfw needs to make use of StringPiece, so
move it to libandroidfw and update all code referencing
StringPiece in aapt2.

ce5e56e243 AAPT2: Rename to match new style
Use Google3 naming style to match new
projects' and open source google projects' style.

Preferred to do this in a massive CL so as to avoid
style inconsistencies that plague legacy code bases.
This is a relatively NEW code base, may as well keep
it up to date.

Test: name/style refactor - existing tests pass

58a20a6482 AAPT2: Change accepted notation for resource names in tests
Previously the way to name resources in tests was to use reference
notation (@[package:][type/]name). Now we use name notation (no @).

d0f116b619 AAPT2: Remove usage of u16string
For legacy reasons, we kept around the use of UTF-16 internally
in AAPT2. We don't need this and this CL removes all instances of
std::u16string and StringPiece16. The only places still needed
are when interacting with the ResTable APIs that only operate in
UTF16.

fb6312fe93 AAPT2: Add version collapsing
When an app specifies (or imports) resources with various
configurations for different SDK versions, specifying
a minSdk will make many of those resources unreachable.

Version collapsing will prune out the resources specified
for SDK versions less than the minSdk.

If, however, there is no exact matching resource for the
minSdk version, the next smallest SDK version is kept.

Mingw32 4.8 is kind of picky with macros and some complicated template
stuff. Luckily there was another way to represent the
SFINAE code that works on all platforms. Yay!

355f285ffd AAPT2: Implement density stripping and initial Split support
When a preferred density is supplied, the closest matching densities
will be selected, the rest stripped from the APK.

Split support will be enabled in a later CL. Command line support is still
needed, but the foundation is ready.
