  This patchset implements the support for reverse bitmap scanning along with
test support. Reverse scanning is quite useful when bit position signifies
an ordering according to some attribute, e.g., priority ordering.

Prerequisite:
* Note that this patchset is dependent on patch:-

This patchset has had no feedback in 5 years.
* There was never an application that needed it.
* EAL directory structure changed.
* It would cause an ABI breakage.

If you have an example that needs it, then rebase and follow ABI
rules and the next ABI change will be for 23.11
