[v3,0/7] Enhance rawdev APIs

  This patchset proposes some internal and externally-visible changes to the
rawdev API, the ABI change of which were previously announced.

The changes are in two main areas:
* For any APIs which take a void * parameter for driver-specific structs,
  add an additional parameter to provide the struct length. This allows
  some runtime type-checking, as well as possible ABI-compatibility support
  in the future as structure change generally involve a change in the size
  of the structure.
* Ensure all APIs which can return error values have int type, rather than
  void. Since functions like info_get and queue_default_get can now do some
  typechecking, they need to be modified to allow them to return error
  codes on failure.

V3:
  - fix doxygen error
  - add release note update for changes to public APIs
V2:
  - add additional patch to make start/stop functions optional
  - remove deprecation notice once changes applied


Bruce Richardson (7):
  rawdev: add private data length parameter to info fn
  rawdev: allow drivers to return error from info function
  rawdev: add private data length parameter to config fn
  rawdev: add private data length parameter to queue fns
  rawdev: allow queue config query to return error
  rawdev: mark start and stop functions optional
  doc: remove rawdev deprecation notice
