This is a cherry-pick of https://googleplex-android-review.git.corp.google.com/#/c/399886/ Instead of storing a kb layout per device descriptor (which is expected to be unique), store it for each vendor/product. This way we can keep a consistent layout between identical but physically different keyboards. There are some corner cases this is expected to fail on, namely devices that incorrectly have the same vendor/product id. Devices that don't define a vendor/product id will continue to use the descriptor to store layout files. Change-Id: I1f2508561992080459310d5a644dad65a9c24f1a
