hwcontext : Add frame context mapping for nontrivial contexts
4 mars 2017, par Mark Thompsonhwcontext : Add frame context mapping for nontrivial contexts
Some frames contexts are not usable without additional format-specific

frames_derive_to to initialise this state appropriately when deriving
a frames context which will require it to be set.(cherry picked from commit 27978155bc661eec9f22bcf82c9cfc099cff4365)
