Rework cpufeature implementation to allow for various cpu feature indications, which is not only limited to hwcap bits. This is achieved by adding a sequential list of cpu feature numbers, where each of them is mapped to an entry which indicates what this number is about. Each entry contains a type member, which indicates what feature name space to look into (e.g. hwcap, or cpu facility). If wanted this allows also to automatically load modules only in e.g. z/VM configurations.
