Userinfo is urlencoded in URIs (RFC 3986)

Thanks to Jean-Baptiste Lallement for spotting and fixing it!

* apt-pkg/contrib/strutl.cc:
  - always escape '%' (LP: #130289) (Closes: #500560)
  - unescape '%' sequence only if followed by 2 hex digit
  - username/password are urlencoded in proxy string (RFC 3986)
