fixPermissions: simplify code, fix bugs

- avoid parsing permission strings - fix memory leaks, a fix new/free mismatch and a compiler warning - fix that only first updated-package was processed - fix a potential stack overflow if packages.xml is huge - minor refactoring for reducing duplicated code - don't process packages without codePath - fix path for deleting app data (currently unused anyway) - fix file ownership on libs - try not to mess up Android 5.0 app permissions Patch set 4 - make fixing SELinux contexts an option with a check box - add some notes / text to the themes Patch set 6 - decouple "fix permissions" from "fix contexts" Change-Id: Icc77ecc581befc5ce6e419b1f3b8ca189208c234
