148c7b7687 stats: counters data model
This adds a new data model for counters.
Specifying the errors severity and unit.
A later patch will update vpp_get_stats to take advantage of this.
Only the map plugin is updates as an example.

New .api language:
A new "counters" keyword to define counter sets.

counters map {
  none {
    severity info;
    type counter64;
    units "packets";
    description "valid MAP packets";
  };
  bad_protocol {
    severity error;
    type counter64;
    units "packets";
    description "bad protocol";
  };
};

Each counter has 4 keywords. severity, which is one of error, info or warn.
A type, which is one of counter64 or gauge64.
units, which is a text field using units from YANG.

paths {
  "/err/ip4-map" "map";
  "/err/ip6-map" "map";
  "/err/ip4-t-map" "map";
  "/err/ip6-t-map" "map";
};

A new paths keyword that maps the counter-set to a path in the stats segment KV store.

Updated VPP CLI to include severity so user can see error counter severity.
DBGvpp# show errors
   Count               Node                    Reason        Severity
        13        ethernet-input              no error         error

f145c15631 map: honor pre-resolve param in map-t
With this commit, forward the translated packet directly to the
specified next-hop if pre-resolve param is enabled in MAP-T.

Type: fix

360b523b52 map: fix coverity issue 205684
ip4_map_get_domain returns d0 = 0 in case of no domain,
and sets error MAP_ERROR_NO_DOMAIN. Rearrange the clauses
in the logical check that relies on dereferencing d0
such that boolean shortcutting takes care of not
referencing the null pointer.

eb284a1f8f ip: functional interface to ip fragmentation
This provides a functional interface to IP fragmentation.
Allowing external features to fragment. Supports
arbitrary encap size, for e.g. MPLS or inner fragmentation
of tunnels.

This also removed dual loop in MAP that was fundamentally broken.

7b2e9fb1a8 map: use ip6-full-reassembly instead of own code
Remove map's implementation of reassembly and use common
ip6-full-reassembly functionality. This makes it easier to maintain by
removing duplicate code/functionality.

Type: refactor

640edcd901 map: use SVR for MAP-T
This change is part of an effort to unify reassembly code. By removing
shallow virtual reassembly functionality in MAP and using the common
vnet provided shallow virtual reassembly, code size and complexity
is reduced.

282093f1fe IPIP and IPv6 fragmentation
- Error where ICMPv6 error code doesn't reset VLIB_TX = -1
  Leading to crash for ICMP generated on tunnelled packets
- Missed setting VNET_BUFFER_F_LOCALLY_ORIGINATED, so
  IP in IPv6 packets never got fragmented.
- Add support for fragmentation of buffer chains.
- Remove support for inner fragmentation in frag code itself.
