List device callback must be able to return valid list without opening device.
This callback should return input values for open function, not vice-versa.

Also the libavutil/ffversion.h will be installed.

Rationale:
* Applications might want to know FFmpeg's version besides the individual
  libraries'.
* Avoids file name clash between FFmpeg's ./version.h and lib*/version.h when
  a library source file includes both and is compiled on an out-of-tree build.

 (git pull for example), anything that includes config.h will be
 recompiled. And that means pretty much every single file in the tree.
"

Avoid clash with version.h of the libraries.
