描述

ZSTD_estimateCCtxSize_usingCCtxParams_internal() currently takes a long list of parameters. Some (all?) of the parameters are extracted from external ZSTD_CCtx_params objects and passed in one by one. It would be cleaner to reduce the number of parameters by directly passing in a ZSTD_CCtx_params const*.

This should be an easy refactor. Code pointer: https://github.com/facebook/zstd/blob/90597d78eadadae7acf3633ab4d81ef7c4e6057f/lib/compress/zstd_compress.c#L1488-L1495

研究方向
Modify the function signature of ZSTD estimateCCtxSize usingCCtxParams internal in lib/compress/zstd compress.c (line 1488) to accept a const pointer to ZSTD CCtx params instead of the individual parameters. Then update all callers of this function to pass the pointer. There may be internal and external callers to consider. Ensure the change is consistent with the existing code style and passes tests.
