Some points of the refactor not sorted by importance:
* Fixed immutability of readers and factories (there are exceptions...)
* Fixed copy constructors and = operators
* Removed messaging system
* Removed reader types
* Added const where possible
* Using initalisers when possible
* Avoided use of pointers when possible
* Removed AUD_NEW and AUD_DELETE macros
* Removed useless NULL pointer checks
* Fixed exception catching
* Fixed some yet unknown bugs
* Lots of other stuff
Error was cased by undefined UINT64_C in stdint.h for c++
programs. As I understand from ffmpeg mailing list the simpliest
solution is to define __STDC_CONSTANT_MACROS before including
ffmpeg libraries. There already was some amout of such definitions in
the code and I've tested this with newer and older ffmpeg
libraries -- this should work and should be safe, but maybe
there is better way of fixing this problem.
