Description
RPM databases can be either in BerkeleyDB format or optionally in the newer "native" NDB format. there are linux distributions that switched their implementation of the rpm database away from BerkeleyDB out of concerns about the future levels of maintenance after its license change.
See https://rpm.org/wiki/Releases/4.14.0
See also https://fedoraproject.org/wiki/Changes/NewRpmDBFormat
This PR supports NDB format reading.
