Patches often need to be applied in a specific order. For OE recipes we
were always storing the Patch objects correct order as they are
refreshed every time the recipe itself is refreshed, however for other
distro comparisons, import_otherdistro.py attempts to preserve existing
records, adds new ones and then deletes whatever is left over, which may
result in the order getting messed up over time. To avoid this issue,
record the order next to the patch and set the model meta-info to use
this to sort Patch queries by default.
