The files are no longer generated by configure, so they should not
be removed by the distclean target any longer.

Now works with --disable-stripping.

Split it off from install-data.

Among other things, this prevents spamming triplicate log lines during install.

This also adds support to avconv (which is trivial due to the new
hwaccel API being generic enough).

The new decoder setup code in dxva2.c is significantly based on work by
Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites.

Merges Libav commit f9e7a2f95a.
Also adds untested VP9 support.
The check for DXVA2 COBJs is removed. Just update your MinGW to
something newer than a 5 year old release.

It's not used by anything, has dubious usefulness, the reasons for which
it was introduced are no longer valid, and only serves to add complexity
to the build system.

Fixes ticket #5546.

Previously, all link-time dependencies were added for all libraries,
resulting in bogus link-time dependencies since not all dependencies
are shared across libraries. Also, in some cases like libavutil, not
all dependencies were taken into account, resulting in some cases of
underlinking.

To address all this mess a machinery is added for tracking which
dependency belongs to which library component and then leveraged
to determine correct dependencies for all individual libraries.

This unclutters the top-level directory and groups related files together.

This moves work from the configure to the Make stage where it can
be parallelized and ensures that pkgconfig files are updated when
library versions change.

Bug-Id: 449

This moves work from the configure to the Make stage where it can
be parallelized and ensures that shared libraries are built with
the right version number in the filename.

This unclutters the top-level directory and groups related files together.

This makes naming more consistent and simplifies extralibs-related changes.

Otherwise builds without explicit target result in silent no-ops.

The library versions are stored in the config.mak file and are used
to derive shared library names.

EXTRALIBS contains general and platform-specific extra libraries
that should be part of all linker commands.

Supporting the system was a nice joke for the 9 release, but it has
run its course. Nowadays Plan 9 receives no testing and has no
practical usefulness.

Since avversion.h is a generated header it must be created before
dependencies can be determined as a side effect of compilation.
Otherwise Make stops and restarts the build process to generate
avversion.h and produces related error messages.

It didn't take into account the new pattern used for bitstream filters
and protocols.

The variable needs to be reset for each subdirectory.

And move the asm recipe to the top-level Makefile next to the other
local pattern rules for .o files.

Generate the files in a single postprocessing step w/o intermediate files.

Split version files into one line per symbol/directive to allow compatibility
with the Solaris linker without preprocessing and eliminate $ from version file
templates to simplify the postprocessing shell command.

Restore alphabetical order in lists, break overly long lines, do some
prettyprinting, add some explanatory section comments, group parts
together that belong together logically.
