*: Rearrange vrf_bitmap_X api to reduce memory footprint
When running all daemons with config for most of them, FRR has
sharpd@janelle:~/frr$ vtysh -c "show debug hashtable" | grep "VRF BIT HASH" | wc -l
3570
3570 hashes for bitmaps associated with the vrf. This is a very
large number of hashes. Let's do two things:
a) Reduce the created size of the actually created hashes to 2
instead of 32.
b) Delay generation of the hash *until* a set operation happens.
As that no hash directly implies a unset value if/when checked.
This reduces the number of hashes to 61 in my setup for normal
operation.
