   Merged from trunk 9274:9279

   | 9275    | don't record internal providers in NEEDED records as they    |
   | genone  | are pointless for all useful applications in portage and     |
   |         | complicate them instead (e.g. bug #205531)                   |

   | 9276    | display errors that occured during package set initalization |
   | genone  |                                                              |

   | 9277    | don't try to copy manually removed libraries (bug #208946)   |
   | genone  |                                                              |

   | 9278    | Make qa_source and qa_call save the return value and return  |
   | zmedico | it. Thanks to igli for suggesting.                           |

   | 9279    | For the useq() IUSE qa check, use [[ $u =~ $PORTAGE_IUSE ]]  |
   | zmedico | instead of egrep since apparently it's compatible in this    |
   |         | case. Thanks to igli for this.                               |
