c3e12e0f03 fib: add dataplane algorithm for IPv6
Add fib implementation for ipv6 using modified DIR24_8 algorithm.
Implementation is similar to current LPM6 implementation but has
few enhancements:
faster control plane operations
more bits for userdata in table entries
configurable userdata size

40d41a8a7b fib: support IPv6
Add FIB library support for IPv6.
It implements a dataplane structures and algorithms designed for
fast IPv6 longest prefix match.

39e9272484 fib: add FIB library
Add FIB (Forwarding Information Base) library. This library
implements a dataplane structures and algorithms designed for
fast longest prefix match.
Internally it consists of two parts - RIB (control plane ops) and
implementation for the dataplane tasks.
Initial version provides two implementations for both IPv4 and IPv6:
dummy (uses RIB as a dataplane) and DIR24_8 (same as current LPM)
Due to proposed design it allows to extend FIB with new algorithms
in future (for example DXR, poptrie, etc).
