/**
  Compress a block of data in the input buffer and returns the size of
  compressed block. The size of input buffer is specified by
  length. The minimum input buffer size is 16.

  The output buffer must be at least 5% larger than the input buffer
  and can not be smaller than 66 bytes.

  If the input is not compressible, or output does not fit in maxout
  bytes, the return value will be 0 and you will have to discard the
  output buffer.

  The acceleration parameter is related with the frequency for
  updating the internal hash.  An acceleration of 1 means that the
  internal hash is updated at full rate.  A value < 1 is not allowed
  and will be silently set to 1.

  The input buffer and the output buffer can not overlap.
