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.

Fixes #1769.

This reverts commit ca21116b.

Revert suggested by Jamal:
"Bad secondary effect i just noticed: Every time version.h is changed
 (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.

Fixes commandline parsing on Cygwin (on 64 bit, and on very recent
32 bit), where the configure check does find the CommandLineToArgvW
function (since it exists in the link libraries and in the headers),
but whose GetCommandLineW() only returns the application's path.
(This is due to a cygwin internal optimization, see
http://cygwin.com/ml/cygwin/2013-07/msg00538.html for details.)
Arguments are only given through main's argc/argv, and they're already

Some C runtime implementations deadlock when calling threading functions
on the atexit() handler.

Use a simpler wrapper similar to av_log to call the cleanup function

Flag added in a few simple filters. A bunch of other filters can likely
use the feature as well.

Example:
Filter overlay
  Overlay a video source on top of the input.
    Inputs:
       #0: main (video)
       #1: overlay (video)
    Outputs:
       #0: default (video)
