  avfoundation: Fix compilation for OSes other than macOS and iOS
  
  E.g. tvOS doesn't have devicesWithMediaType.
  
  In principle, we could probably disable building the whole
  input device on such OSes, but that would either require
  testing explicitly for the OS type in configure (which we don't
  do anywhere so far), or test for individual objective C methods.
  
  This approach allows the code to compile, but no input devices
  will be found at runtime.

  configure: Add a dependency for the audiotoolbox outdev
  
  The audiotoolbox outdev uses APIs that only are available on macOS,
  not on iOS or tvOS. Check for them in configure, and make sure the
  outdev is disabled otherwise.
  
  This allows building for iOS without explicitly having to disable
  the audiotoolbox outdev.

• avcodec/mpegvideo_enc : Don't use unnecessarily much stack

  avcodec/mpegvideo_enc: Don't use unnecessarily much stack
  
  encode_thread() puts two MPVEncContexts (2*6516B here)
  on the stack and zeroes one of them in order to
  temporarily store the variables that get changed
  during encoding a macroblock (when there is more than
  one candidate type for a macroblock). This is wasteful
  and therefore this commit adds a small (328B here) structure
  to store exactly the fields that actually need to be backed
  up. Then one can extend MPVEncContext without fearing
  too use up to much stack.
