* apt-pkg/pkgcache.h:

  - switch {,Install-}Size to unsigned long long
  - deal with long long, not with int to remove 2GB Limit (LP: #250909)
  - deprecate AddSize with Multiplier as it is unused and switch to
    boolean instead to handle the sizes more gracefully.
  - switch i{Download,Usr}Size from double to (un)signed long long
* cmdline/apt-get.cc:
  - use unsigned long long instead of double to store values it gets
