* use the new CacheFile::ListUpdate() code

* add example in doc/examples/update.py
* python/pkgrecords.cc:
  - export the Homepage field
* python/tar.cc:
  - fix .lzma extraction (thanks to bigjools)
* python/sourcelist.cc:
  - support GetIndexes() GetAll argument to implement
    something like --print-uris
* python/apt_pkgmodule.cc:
  - add InstState{Ok,ReInstReq,Hold,HoldReInstReq} constants
* apt/cache.py:
  - add reqReinstallPkgs property that lists all packages in
    ReInstReq or HoldReInstReq
