Adds output of chroma sub-sampling information to
ffprobe -show_pixel_formats option.
Note: This patch just prints the "raw" log2_charoma_w/h values instead
of the previously suggested mapping into a chroma sub-sampling pattern
string like "4:2:2".

The old API required this clearing in the past, the new API does not
require it.

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 ca21116b3f.
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.

Fix warning:
ffprobe.c:1684:21: warning: ‘start’ may be used uninitialized in this function [-Wmaybe-uninitialized] end = start + interval->end;
The warning is a false positive, since the variable is accessed only if
has_start is set, and in that case start has been already set.
The option is used to sort the streams by program.

This fixes rendering of sections containing nested elements followed by
an array, for example as in the case:
programs->streams->stream
enabled by the -show_programs option.
Without this fix, ffprobe would exit with a failure exit code if a stream
specifier is given that selects the last stream.

Avoid access to uninitialized values, which may result in a crash.
This happens for example in case of option parsing failure, since in that
case the internal AVBprint buffers are not initialized.
