* [BREAK] merged lp:~mvo/apt/history

  - this writes a /var/log/apt/history tagfile that contains details
    from the transaction (complements term.log)
* methods/http.cc:
  - add cache-control headers even if no cache is given to allow
    adding options for intercepting proxies
  - add Acquire::http::ProxyAutoDetect configuration that 
    can be used to call a external helper to figure out the 
    proxy configuration and return it to apt via stdout
    (this is a step towards WPAD and zeroconf/avahi support)
* abicheck/
  - add new abitest tester using the ABI Compliance Checker from
    http://ispras.linuxfoundation.org/index.php/ABI_compliance_checker
* Change the package index Info methods to allow apt-cache policy to be
  useful when using several different archives on the same host.
