Thanks @ahresse! We will look at the best way to apply all of these changes internally and then publish them on GitHub.

[ahresse]

These two commit got applyed to debian.native:

• debian: set libcmocka-mocks-dev section to libdevel f402a94
• debian: set cmocka-mocks-doc section to doc d7407e5

I rebased the remaining one to branch main.

@ahresse we applied your changes to debian.native on the main branch. With the latest release for debian we published it for the debian/main.
Please have a look if you miss something otherwise we can close this as merged.

I re-based remaining commits on current main (7cf0b19) to make this PR ready for merge.

Yes, I see we have here different ideas on how to categorize our mock-libraries. Our thought is , the libmock-mylib provides mocks used to develop unit tests when I link against mylib.

@ahresse What are your thoughts about libmock-xy and section : lib vs libdevel ?
