[ofw] [Patch 39/62] Reference implementation of NDv2

[Fab Tillier]

Export UVP entry points directly.

This patch makes it so that the ND provider can call directly into the UVP, without having to query/user the UVP interface structure from IBAL.  Going forward, these entry points will be optimized for performance, taking native ND structures as input, optimizing locking, etc.
