[pacman-dev] [PATCH] Clean up handling of size fields

We currently have csize, isize, and size concepts, and sometimes the
difference isn't clear. Ensure the following holds:
* size (aka csize): always the compressed size of the package; available
for everything except local packages (where it will return 0)
* isize: always the installed size of the package; available for all
three package types
