[PATCH 0/1] MR3620: crypt32: Fix CMS SignedData encoding.

[Torge Matthies (＠tmatthies)]

Several items here were encoded conditionally even though they aren't marked as optional in the spec.

I put the tests into the same commit as the fix because the helper function used throughout the file, check_param, does not support marking only some of the tests inside of it as todo_wine.
