libav/ffmpeg: Compile/Link 2 versions of native FFMPEGMediaPlayer methods FFMPEGNatives -> FFMPEGv08Natives + FFMPEGv09Natives

Enables FFMPEGMediaPlayer to work w/ either ffmpeg/libav version 8 or 9 w/ same JOGL binary

Same C source code is compiled against
  1: version 0.8  FFMPEGv08Natives lavc53.lavf53.lavu51
  2: version 0.9  FFMPEGv09Natives lavc54.lavf54.lavu52.lavr01

FFMPEGv08Natives and FFMPEGv09Natives implements FFMPEGNatives,
native C code uses CPP '##' macro concatenation to produce unique function names.

To enable 'cpp' to find the libav* header files matching the desired version,
we have placed them in the c-file's folder, issued '#include "path/file.h"
and added symbolic links to allow finding same module and 'sister modules':

ls -l libavformat/
..
lrwxrwxrwx 1 sven sven    13 Aug 26 12:56 libavcodec -> ../libavcodec
lrwxrwxrwx 1 sven sven    14 Aug 26 12:56 libavformat -> ../libavformat
lrwxrwxrwx 1 sven sven    12 Aug 26 12:57 libavutil -> ../libavutil
..

At static init FFMPEGDynamicLibraryBundleInfo, determines the runtime version
and instantiates the matching FFMPEGNatives, or null if non matches.

FFMPEGMediaPlayer still compares the compile-time and runtime versions.

FFMPEGMediaPlayer passes it's own instance to FFMPEGNatives for callbacks.
