* the repository plist index file in the "unsorted_deps" array.
*
* When a package has no rundeps or all rundeps are satisfied, the package
* dictionary is added into the "packages" array and it is removed from the
* "unsorted_deps" array; that means the package has been sorted in the
* transaction.
* dictionary is added into the sorted "packages" array and it is marked as
* sorted in its dictionary with a boolean object.
*
* It will loop until all packages are processed and will check that
* the number of packages added into the "packages" array is the same than
* it was in the "unsorted_deps" array.
*
* Sure I could make it not iterate so many times but probably it will
* also be slower! that's why XBPS uses proplib with its red-black trees,
* iterating over them is fast.
