  Migrate to github actions (#920)
  
  Not all combinations are migrated to the initial configuration; corresponding TODOs added.
  
  Drive-by: additional combinations uncovered minor portability problems -> fixed
  Drive-by: remove no-longer used "script" files.

  .SS "#define BROTLI_LARGE_MAX_DISTANCE_BITS   62U"
  
  .PP
  The theoretical maximum number of distance bits specified for large window brotli, for 64-bit encoders and decoders\&. Even when in practice 32-bit encoders and decoders only support up to 30 max distance bits, the value is set to 62 because it affects the large window brotli file format\&. Specifically, it affects the encoding of simple huffman tree for distances, see Specification RFC 7932 chapter 3\&.4\&. 
  .SS "#define BROTLI_LARGE_MAX_WBITS   30"
  
  .PP
  The maximum supported large brotli window bits by the encoder and decoder\&. Large window brotli allows up to 62 bits, however the current encoder and decoder, designed for 32-bit integers, only support up to 30 bits maximum\&. 
  .SS "#define BROTLI_MAX_NPOSTFIX   3"
  
  .PP
  Maximal number of 'postfix' bits\&. Number of 'postfix' bits is stored as 2 bits in meta-block header\&. 
  .SH "Author"
