* apt-pkg/depcache.cc:

  - switch i{Download,Usr}Size from double to (un)signed long long

The biggest reason is that this saves a lot of float point operations
we do in AddSizes() on integers. The only reason i see that this was
a double is that it was 64bit long and can therefore store bigger
values than int/long, but with the availablity of (un)signed long long
we are now also at 64bit and can store sizes more than 8 Exabytes big -
by the time this will be a limit the C/C++ Standard will have bigger types,
hopefully.
