b1ec94e63c Fix ZSTD_f_zstd1_magicless for small data 
* Fix `ZSTD_FRAMEHEADERSIZE_PREFIX` and `ZSTD_FRAMEHEADERSIZE_MIN` to
  take a `format` parameter, so it is impossible to get the wrong size.
* Fix the places that called `ZSTD_FRAMEHEADERSIZE_PREFIX` without
  taking the format into account, which is now impossible by design.
* Call `ZSTD_frameHeaderSize_internal()` with `dctx->format`.
* The added tests catch both bugs in `ZSTD_decompressFrame()`.

Fixes #1813.

37f47e51a8 fixed datagen 
to produce same content on both 32 and 64-bit platforms
by removing floating from literal table determination.

also : added checksum trace in compression control test,
so that it's easier to determine if test fails
as a consequence of compressing a different sample.
