LCppC backport: Replaced check for pipe() buffer size by ordinary CheckBufferOverrun

[PKEuS]

As a follow-up to the discussion in PR4143, I am starting to provide a few fixes/improvements from LCppC to cppcheck, starting with those I backported and sent do danmar a year ago, but were not applied to cppcheck for unknown reasons.

I tried to fix/update this rng file, but apparently I failed. Can someone please explain how this has to look like?

[danmar]

Did you try this:

<optional>
    <attribute name="baseType"><text/></attribute>
</optional>

[PKEuS]

Thanks, trying that out.

[danmar]

👍 for replacing hard coded checking with configuration

man/reference-cfg-format.md documentation should be updated about this new attribute.

Also, with all these PRs, you should consider updating release-notes.txt with all these new features so it will be added to the notes for next release.

yes. however for this PR there is no new checker so I guess the release-notes.txt can be kept.
