Unbreak the build against recent Clang by backporting two patches from the

upstream (issue #1537368):

  - Unconditional usage of std::auto_ptr<> in "vigra_ext" code:
    http://hg.code.sf.net/p/enblend/code/rev/467a73754dbb

  - Get rid of `boost::assign::map_list_of' (additional patch):
    http://hg.code.sf.net/p/enblend/code/rev/73e6f16de80a
