OS String descriptor can be provided by using FunctionFS with configfs. In order for FunctionFS to support Feature Descriptors, corresponding Extended Compatibility and Extended Properties descriptors must be passed to ep0. This series adds parsing the said descriptors and setting up appropriate internal data structures. Rebased onto Felipe's testing/next. This is meant for 3.17. v1..v2: - changed confused naming of two existing functions - OS descriptors proper implementation with fixes suggested by Michal; thanks, Michal!
