Neale Ranns 097fa66b98 fib: fib api updates 
Enhance the route add/del APIs to take a set of paths rather than just one.
Most unicast routing protocols calcualte all the available paths in one
run of the algorithm so updating all the paths at once is beneficial for the client.
two knobs control the behaviour:
  is_multipath - if set the the set of paths passed will be added to those
                 that already exist, otherwise the set will replace them.
  is_add - add or remove the set

is_add=0, is_multipath=1 and an empty set, results in deleting the route.

It is also considerably faster to add multiple paths at once, than one at a time:

vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11
100000 routes in .572240 secs, 174751.80 routes/sec
vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.12
100000 routes in .528383 secs, 189256.54 routes/sec
