Port TrueZip revision 6207 to Android:
- Downgraded to fully comply with JS6 (required to build in Android)
- Removed NIO2, ServiceLocator, Swing and console classes (not availaible in Android)
- Stripped down to use the minimal subset of classes to run File, Zip and RAES engines
- Removed javax/findBugs annotations (not availaible in Android)
- Removed registered implementations (fsdrivers and keyproviders) from locators,
  which doesn't have any implementation. Implemetators should define its own subsets of
  drivers and keyproviders.
