linux: simplify adding new extensions
Curently, all three linux extensions follow the same layout: - test if the extension is enabled - add itself to linux' patch-dependencies - declare a macro, added as the pre-patch hook Except for the macro, all can be commonalised. Add a simple infrastructure for that: - extensions declare themselves in the list of extensions - extensions define their macro - the infra adds them to the patch-dependencies and pre-patch hooks as appropriate Signed-off-by: "Yann E.
