Sean McGovern cdd139d760 libavcodec/alpha: remove DSP & support code 
Introduced in 1992, the Alpha was a 64-bit RISC processor designed
to replace the VAX CISC machines sold by Digital Equipment Corporation.

After Digital was acquired by Compaq in 1998 -- who themselves would be
later purchased by Hewlett-Packard, the architecture was phased out over
the following decade. It became effectively defunct in 2007, the last
publicly available processor being the Alpha 21364.

FFmpeg has not added any DSP code for this architecture since lowres2
was introduced in 2012, and it is more than unlikely someone still wishes
to maintain it.

Remove the DSP and support code.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
