  FTBFS with libav9

Bug description:
  Imported from Debian bug http://bugs.debian.org/692809:

  Audacity currently FTBFS with libav 9:

  [Impact]
  Without libav support, you cannot import/export various audio file types (.ac3, .wma, .m4a, .opus, ...). Previous Ubuntu releases had libav support enabled.

  [Testcase]
  1) Create an .ac3 and/or .wma audio file.
  2) Open Audacity
  3) Select File -> Open -> Open the .ac3/.wma file.

  Audacity should open the .ac3 and .wma file instead of showing an
  error that Audacity does not support this file type.

  [Regression Potential]
  The patch re-introduces libav support again. Major changes in the FFmpeg module were needed to support libav 9 and newer. There could be (new) bugs in the libav import/export due to these changes. Because no other files were touched, there shouldn't be regressions in other parts of the program.
