b0352b1997 avcodec: export motion vectors in frame side data on demand 
The reasoning behind this addition is that various third party
applications are interested in getting some motion information out of a
video "for free" when it is available.

It was considered to export other information as well (such as the intra
information about the block, or the quantization) but the structure
might have ended up into a half full-generic, half full of codec
specific cruft. If more information is necessary, it should either be
added in the "flags" field of the AVMotionVector structure, or in
another side-data.

This commit also includes an example exporting them in a CSV stream.

bf411fffd4 examples: rename avcodec.c to decoding_encoding.c 
Restore the old name, which was more meaningful and consistent with the
names of the other examples.

e53becc70f examples/Makefile: give priority to pkg-config flags 
In case CFLAGS/LDLIBS are already defined and conflicting with the
pkg-config flags, give priority to the latter since they are used to
detect compilation flags.

This should fix for example the case where there are many different
instances of a library, CFLAGS=-I/foo/include and pkg-config cflags say
-I/bar/include.

c0bca6425d examples/decoding_encoding: store temporary files in current dir

Also add the clean-test Makefile rule, which will clean the generated
files.

aecf0cf5ed doc/examples: add audio decoding/filtering example. 
Mostly based on doc/examples/filtering.c. lavfi API is still limited to
"buffer feeding" instead of "frame feeding" at the moment, so this
example code sticks with it.
