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 Change-Id: Id9fdfcf0e62406a8896aa811314dfc08d5f6ed95
