lib: Convert vrf bit-map to a hash.

Memory sizes of the vrf bit-map was insane for a system
with a moderate number of data on it:

Zebra:
VRF bit-map                   :        601   65536            39391944

Having a full 32bit integer bit space is problematically large,
switch over to a hash to store bit data.  We do not need to waste
so much space.

VRF bit-map                   :         13       8                 312
