  MythDeinterlacer: Add linearblend implementation as 'medium' option

- this replaces libavfilter's yadif as the 'medium' quality software
deinterlacer
- the high option is now yadif
- assistance is available from SSE2 and Neon on supported platforms
(which should be most)
- with SIMD support available, this is actually faster than onefield/bob
and offers better quality
- NOTE: Neon support must be explicity enabled at configure time
- for Pi2/3/4 this means:-
  ./configure --cpu=cortex-a7 --arch=armv7 --extra-cflags='-mfpu=neon'
--extra-cxxflags='-mfpu=neon'
