This reverts commit fa254368.

It is too dangerous to not pin the version rados to exact version.

Removed the changelog entries for 4.0-2 from cta.spec.in.  The updated version of these should be put back when the next release is made

[cta-admin] Corrected the showqueues command in the case ArchiveForUser and ArchiveForRepack exist for the same tapepool

utils::trimString() now returns an empty string if the string passed in parameter contains only white-space characters

Fixed.
