merge FAAD2 - the GPL AAC decoder library.

xine_decoder.c is working, but demux_qt must send some needed
initialization data. currently it's hardcoded to play my test stream, so
it's not usable yet.

+/* fftwf77.c:
+
+   FORTRAN-callable "wrappers" for some of the FFTW routines.  To
+   make these routines callable from FORTRAN, three things had to
+   be done:
+
+   * The routine names have to be in the style that is expected by
+     the FORTRAN linker.  This is accomplished with the F77_FUNC_
+     macro.  (See the file "f77_func.h".)
+
+   * All parameters must be passed by reference.
+
+   * Return values had to be converted into parameters (some
+     Fortran implementations seem to have trouble calling C functions
+     that return a value).
+
+   Note that the "fftw_plan" and "fftwnd_plan" types are pointers.
+   The calling FORTRAN code should use a type of the same size
+   (probably "integer").
+
+   The wrapper routines have the same name as the wrapped routine,
+   except that "fftw" and "fftwnd" are replaced by "fftw_f77" and
+   "fftwnd_f77".
