daff178403 DHCP Client Dump
- use types on the DHCP API so that the same data is sent in comfing messages and in dumps
- add the DHCP client dump API
- update VOM to refelct API changes
- rename VOM class dhcp_config* dhcp_client*
- the VOM dhcp_client class maintains the lease data (which it reads on a dump) for clients to read

Add a few dhcp client rx packet/state counters

Temporarily disable the dhcp client unit test, since it trips over the

54c6dc4500 For DHCP client configuration control the setting of the broadcast flag in the
DISCOVER message sent.

According to RFC2131:

   In the case of a client using DHCP for initial configuration (before
   the client's TCP/IP software has been completely configured), DHCP
   requires creative use of the client's TCP/IP software and liberal
   interpretation of RFC 1122.  The TCP/IP software SHOULD accept and
   forward to the IP layer any IP packets delivered to the client's
   hardware address before the IP address is configured; DHCP servers
   and BOOTP relay agents may not be able to deliver DHCP messages to
   clients that cannot accept hardware unicast datagrams before the
   TCP/IP software is configured.

   To work around some clients that cannot accept IP unicast datagrams
   before the TCP/IP software is configured as discussed in the previous
   paragraph, DHCP uses the 'flags' field [21].  The leftmost bit is
   defined as the BROADCAST (B) flag.  The semantics of this flag are
   discussed in section 4.1 of this document.  The remaining bits of the
   flags field are reserved for future use.  They MUST be set to zero by
   clients and ignored by servers and relay agents.  Figure 2 gives the
   format of the 'flags' field.

this changes means VPP conforms to the:
   "SHOULD accept and forward to the IP layer any IP packets delivered
    to the client's hardware address before the IP address is configured"
with the caveat that VPP allows DHCP packets destined to the stanard client
DHCP port to be delivered. With this enhancement the control-plane is now
able to choose the setting of the broadcast flag.

Enhence support of DHCP VSS (Virtual Subnet Selection) to include
VSS type 0 where VSS info is a NVT (Network Virtual Terminal)
ASCII VPN ID where the ASCII string MUST NOT be terminated with a
zero byte. Existing code already support VSS type 1, where VSS
information is a RFC 2685 VPN-ID of 7 bytes with 3 bytes OUI
and 4 bytes VPN index, and VSS type 255 indicating global VPN.

1500254bee FIB table add/delete API
part 2;
  - this adds the code to create an IP and MPLS table via the API.
  - but the enforcement that the table must be created before it is used is still missing, this is so that CSIT can pass.

808c5b21c2 DHCP Client: receive unicast ACKs
despite VPP DHCP client setting neither ciaddr nor giaddr and setting the broadcast bit (see RFC 2131 section 4.1) some DHCP servers will still send a unicast DCHPACK. So as not to drop this VPP must have both 1) a receive FIB entry for the OFFERED IP adress and 2) a 'don't drop me because of uRPF' FIB entry for the DHCP server's address.

3466c30261 DHCP Multiple Servers (VPP-602, VPP-605)
Multiple DHCP (4 and/or 6) servers can be added and removed through multiple calls to the 'set dhcp server' API.
All 4/6/ discover/solicit messages will then be replicated to all servers in the list. The expectation is that the servers/system is configured in such a way that this is viable.
If VSS information is providied for the clinet VRF which also has multiple servers configured, then the same VSS information is sent to each server. Likewise the source address of packets sent to from VPP to each server is the same.

2dd6852d81 Consolidate DHCP v4 and V6 implementation. No functional change intended
The DHCP proxy and VSS information maintained by VPP is the same for v4 and v6, so we can manage this state using the same code.
Packet handling is cleary different, so this is kept separate.

20a175a184 dhcp: multiple additions
DHCP additions:
1) DHCPv4 will only relay a message back to the client, if the Option82 information is present. So make this the default.
2) It is no longer possible to select via the API to "insert circuit ID" - since this is now default
3) Remove the version 2 API since it's now the same as version 1.
4) Adding the VSS option is now conditional only on the presence of VSS config (not the 'insert' option in the set API)
5) DHCP proxy dump via API

32e1c010b0 IP Multicast FIB (mfib)
- IPv[46] mfib tables with support for (*,G/m), (*,G) and (S,G) exact and longest prefix match
 - Replication represented via a new replicate DPO.
 - RPF configuration and data-plane checking
 - data-plane signals sent to listening control planes.

The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast.

'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests.

Updated applications to use the new MIFB functions;
  - IPv6 NS/RA.
  - DHCPv6
 unit tests for these are undated accordingly.
