AAPT2

First checking of AAPT2. The individual phases of AAPT2 work, but there
are some missing pieces.

For early testing we are missing:
- Need to properly mark file references and include them in package
- Need to package into zip

Final AAPT for apps we are missing:
- Need to crush PNGs
- Need to parse 9-patches
- Need to validate all of AndroidManifest.xml
- Need to write align method to align resource tables for splits.

Final AAPT for apps + system we are missing:
- Need to handle overlays
- Need to store comments for R file
- Need to handle --shared-lib (dynamic references too).

New AAPT features coming:
- Need to import compiled libraries
    - Name mangling
    - R file generation for library code
