Plumbing in PackageManager and installd for multi-user support.
- Create /data/user directory and symlink /data/user/0 -> /data/data for
backward compatibility
- Create data directories for all packages for new user
- Remove data directories when removing a user
- Create data directories for all users when a package is created
- Clear / Remove data for multiple users
- Fixed a bug in verifying the location of a system app
- pm commands for createUser and removeUser (will be disabled later)
- symlink duplicate lib directories to the original lib directory
