package_manager.py, rootfs.py, sdk.py: add Indexer class

Because the package-index.bb needs to create package indexes outside
do_rootfs environment, move the indexing capability out of
PackageManager class to a smaller Indexer class.

This commit:
 * simply moves the indexing functions for ipk/deb with no changes;
 * rewrites the RPM indexing function so that it can be easily moved out
   of the PackageManager class;
 * removes some RPM duplicate code, moves it into a method inside
   RpmPM class and changes the RpmPM constructor so that the new method
   is effective;
