fib: Table Replace

Type: feature

from the API doc, a table replace is:

"
    The use-case is that, for some unspecified reason, the control plane
    has a very different set of entries it wants in the table than VPP
    currently has. The CP would thus like to 'replace' VPP's current table
    only by specifying what the new set of entries shall be, i.e. it is not
    going to delete anything that already eixts.
    the CP delcartes the start of this procedure with this begin_replace
    API Call, and when it has populated all the entries it wants, it calls
    the below end_replace API. From this point on it is of coursce free
    to add and delete entries as usual.
    The underlying mechanism by which VPP implements this replace is
    purposefully left unspecified.
"

In the FIB, the algorithm is implemented using mark and sweep.

Algorithm goes:
1) replace_begin: this marks all the entries in that table as 'stale'
2) download all the entries that should be in this table
 - this clears the stale flag on those entries
3) signal the table converged: ip_table_replace_end
 - this removes all entries that are still stale

this procedure can be used when an agent first connects to VPP,
as an alternative to dump and diff state reconciliation.

dhcp: ipv6 prefix delegation improvements

Autoconfigure router advertisements for delegated prefixes.

Clean up a longstanding issue. If vpp receives a dhcpv6 renew reply,
do NOT reset per-delegated-prefix timers. That prevented vpp from
sending a solicit to renew the delegation on time. That, in turn
caused the RA code to send advertisements with valid_time =
preferred_time = 0.  That causes almost any downstream client to throw
away its delegated address.

Miscellaneous changes

o src/vnet/ip/ip6_neighbor.c - always memset elements allocated from pools
  to zero. DGMS.
o Remove debug spew from the ipv6 connection-tracker plugin
