Fixes use of the example with encoders which use tha AVFrame w/h/pix_fmt fields
FFV1 is one of these codecs
We cannot easily workaround the not set fields in common code because the API
has AVFrame constant for the encoders.
Alternatives would be to fix the API or to duplicate the struct and fill in
missing fields. Or as is to require all user apps to set this correctly and
maybe simplify for that case

This reverts commit 792845e436, reversing
changes made to 1d6666a6b8.
Bumping libavutil requires all libraries that use libavutil to have their
major version bumped (yes breakage has been confirmed this is not a hypotheses)
One case of breakage is due to new types being added to AVOptions and
applications that linked to old libavutil and libswresample
then trying to use old libavutil (its soname changed so the old isnt updated)
and new swresample (its soame didnt change so it is updated)
the new swresample contains AVOption types that the old libavutil doesnt
know of thus the application attempting to access these avoptions
fails
AVOptions are used by all libs so the issue can potentially happen with
any other lib, libswresample was just the first that showed the problem
ive not checked if the other libs are affected currently by the same issue
or not
Also in addition to AVOptions, AVFrames are also defined in
libavutil, bumping it without all libs that use AVFrames could lead to
serious inconsistencies when 2 libs/app end up using 2 different libavutils
The alternative of bumping all is still possible after this revert, if it
turns out to be the preferred solution

Signed-off-by: Stefano Sabatini <stefasab@gmail.com>
Applications that have been linked against an older release of Libav and pick up
updated libraries experience segmentation faults because they pick up the new
libavfilter, which assumes AVFrames have been allocated by libavutil and thus
contain new reference-counting related fields. This will break for AVFrames that
have been allocated by old libavcodec.
All scheduled API changes are deferred to the next bump.
Commit 41578f70cf changed the LLS API, which was
called from libavcodec. Thus using an old libavcodec with a new libavutil will
break.
All scheduled API changes are deferred to the next bump.
The open_codec_context function, when it fails to find a codec, now
return AVERROR(EINVAL) to signal an error.
Before it would return the stream index, which was always >= 0, and
continue as if a codec was found. This change make it fail faster,
instead of repeated failed tries to decode frames with no codec.

Replace the inline awk script with a Perl script which tracks the
dependencies recursively.
This allows to correctly track dependencies for files including files
with a second level include (for example: ffmpeg-devices.texi ->
devices.texi -> outdevs.texi).
This also adds a dependency on perl for computing the dependencies, which
should not be a problem since perl is already required all the way for
building documentation.
This is a variant of commit 628ceac652
which was reverted due to out-of-tree build failure.
Support the case when multiple frames are contained in a single packet.
In particular, fix fate-samples/lossless-audio/luckynight-partial.shn
sample decoding.

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.

XvMC has long ago been superseded by newer acceleration APIs, such as
VDPAU, and few downstreams still support it. Furthermore XvMC is not
implemented within the hwaccel framework, but requires its own specific
code in the MPEG-1/2 decoder, which is a maintenance burden.
The file was written in 2006, it was never updated nor really used as
