Patchbot failure metaticket

[Maarten Derickx]

The goal of this metaticket is to make it easy to see if there is already a ticket for failures of some patchbots. If a patchbot failure is not on the list, please make a ticket for it if it does not yet exist and add it here together with a list of the affected files!
