Only load extra table positions for CDicts Zstdmt uses prefixes to load the overlap between segments. Loading extra positions makes compression non-deterministic, depending on the previous job the context was used for. Since loading extra position takes extra time as well, only do it when creating a `ZSTD_CDict`. Fixes #1077. 2018-04-02 21:41:30 +00:00			`void const* end, ZSTD_dictTableLoadMethod_e dtlm);`
