Issue:
Let iperf3 server run via ldp and vcl on top of vpp's host stack. If
iperf3 client connects this iperf3 server with tcp MSS setting option,
iperf3 server will always crash.
Root cause:
When MSS option is specified by iperf3 client, iperf3 server will
recreate the listening socket firstly, then call setsockopt() to set MSS
immediately. Iperf3 code can be referred here:
58332f8154/src/iperf_tcp.c (L186).
However, in vcl layer vpp_evt_q of this recreated session is not
allocated yet. So iperf3 server crashes with vpp_evt_q null pointer access.
Fix:
Add session vpp_evt_q null pointer check in vcl_session_transport_attr().
Add a vcl test case for this MSS option scenario.

If ip4_neighbor_probe (or any other) is sending packet to a deleted interface,
ASSERT trips and dataplane crashes. Example:
create loopback interface instance 0
set interface ip address loop0 10.0.0.1/32
set interface state GigabitEthernet3/0/1 up
set interface state loop0 up
set interface state loop0 down
set interface ip address del loop0 10.0.0.1/32
delete loopback interface intfc loop0
set interface state GigabitEthernet3/0/1 down
set interface state GigabitEthernet3/0/1 up
comment { the following crashes VPP }
set interface state GigabitEthernet3/0/1 down
This sequence reliably crashes VPP:
(gdb)p n->name
$4 = (u8 *) 0x7fff82b47578 "interface-3-output-deleted”
If the interface doesn't exist, return ~0 and be tolerant of this in the
two call sites of counter_index()

Currently, neighbor adjacencies on a wg interface are converted into a
midchain only if one of the peers has a matching allowed prefix
configured. If create a route that goes through a wg interface but the
next-hop address does not match any allowed prefixes, an ARP/ND request
will try to be sent via the wg interface to resolve the next-hop address
when matching traffic occurs. And sending an ARP request will cause VPP
to crash while copying hardware address of the wg interface which is
NULL. Sending an ND message will not cause VPP to crash but the error
logged will be unclear (no source address).
With this fix, convert all neighbor adjacencies on a wg interface into a
midchain and update tests to cover the case. If there is no matching
allowed prefix configured, traffic going such routes will be dropped
because of "Peer error". No changes if there is matching allowed prefix
configured.
Also, fix getting peer by adjacency index.

The flow_report_process_send() function always allocates a frame.
However, when no template_send is needed, template_bi is ~0.
When this happens, no vectors are placed in the frame. When
the frame is then "put", a check for n_vectors == 0 prevents
the frame from actually being placed back on the free list.
Fix that by using a direct call to vlib_frame_free() when
there are no frame vctors.

A packet passing through nat44-ei-in2out-output,
has its ttl value validated in earlier nodes.
"ip4-input" node checks ttl for locally generated packets.
"ip4-rewrite" node validates ttl in forwarded packets.
Thus for example, the ED counterpart disables ttl checks
in its "nat44-ed-in2out-output" node.
This patch updates nat44 EI conditions for ttl checks to
those currently used in nat44 ED case, meaning no extra ttl
validation for in2out when output-feature is enabled.

This patch makes the `make docs` directive incremental
avoiding re-running the siphon when the source hasn't
changed, and leveraging sphinx internal cache.
It adds a `make rebuild-docs` directive for cases where
this caching logic might break, e.g. in CI.
The virtualenv doesn't also get recreated on each build,
which might be enough when writing docs, provided
automated process leverage its rebuild counterpart.

A node name is not bound to a node index. For example, if an interface
is deleted and re-added, the indexes of its nodes "<itfc_name>-tx"
and "<itfc_name>-output" may change. Thus, when the collector updates
the nodes stats, it should first delete all the symlinks for nodes that
have changed their names before adding new symlinks. Otherwise, it
could attempt to add already existing symlinks or delete valid ones.
Example of a series of command that triggers a crash in the assert
`ASSERT (node_data[i].symlinks[j] != CLIB_U32_MAX);`:
```
create loopback interface
create loopback interface
```
Wait for the nodes stats to update, then:
```
delete loopback interface intfc loop0
delete loopback interface intfc loop1
create loopback interface
create loopback interface
```
