    This is a partial revert of aa03004ace2fabb135a6208ef8c2d2b312aa7b0b. The
    approach that was taken leads to disagreement and the change was pushed
    too early. DISTRO_PR is going to say and will be used inside the package
    creation. There will be more disucssion on the list about where to continue
    from here.

    Allow a distribution to globally bump the PR of every package
    this is useful when there was a change in the toolchain and
    every package is going to be different.

    find packages/ \( -name '*.bb' -or -name '*.inc' \) -exec sed -i s/"^PR="/"FILE_PR ="/ {} \;
    find packages/ \( -name '*.bb' -or -name '*.inc' \) -exec sed -i s/"^PR ="/"FILE_PR ="/ {} \;

performing the update-alternatives actions.

    Rework the way patches are handled.  There are now two abstract base classes,
    initialized in patch.bbclass.  One for patchset operations on a directory, and
    another for patch failure resolution.  Currently includes 'patch' and 'quilt'
    concrete PatchSet classes, and a 'user' resolver class, which simply drops you
    into a shell in the source tree to fix the rejects.

    Use require for the BitBake files within packages. In contrast
    to the conf files the authors of these files expected these files
    to be included.
