PKCS#7 and CMS overlap heavily - deprecate (part of) PKCS7 #18919
Description
As already mentioned in #18915, there is enormous overlap between the implementations of CMS and PKCS#7, which is no wonder because these two standards are basically the same.
This causes confusion and extra maintenance effort and is evidently prone to inconsistencies.
Would be good to
- consolidate the two implementations
- deprecate the export of detailed data structures for PKCS#7 and many related functions.
Looks like the issue originates from

And so it begins...
Initial support for CMS.
Add zlib compression BIO.
Add AES key wrap implementation.
Generalize S/MIME MIME code to support CMS and/or PKCS7.
while the PKCS7 implementation was of course older:
