  libfdk-aacdec: Correct buffer_size parameter
  
  The timeDataSize argument to aacDecoder_DecodeFrame() seems undocumented
  and until 2016 04 (203e3f28fbebec7011342017fafc2a0bda0ce530) unused.
  After that commit libfdk-aacdec interprets it as size in sample units
  and memsets that on error.
  
  FFmpeg as well as others (like GStreamer) did interpret it as size in
  bytes.
  
  Fixes: 1442/clusterfuzz-testcase-minimized-4540199973421056 (This requires recent libfdk to reproduce)

  configure: Fix handling of _select dependencies
  
  The handling of _select dependencies had two issues:
  
  1) extralibs from _select dependencies of a component were not added to
     the list of extralibs for that component.
  2) extralibs from dependencies were only added to the extralibs of a
     component if the component was enabled. This led to incorrect results
     if that component was enabled by another component later in the dependency
     resolution process. Instead, always generate the full list of component
     extralibs for use later in the dependency resolution process.
  
  Also remove a leftover unused variable.

  tls: Hide backend implementation details from users
  
  TLS is currently implemented over either OpenSSL or GnuTLS, with more
  backends likely to appear in the future. Currently, those backend libraries
  are part of the protocol names used during e.g. the configure stage of a
  build. Hide those details behind a generically-named declaration for the
  TLS protocol to avoid leaking those details into the configuration stage.
