Update the expression for a conditional block which should be executed
when an encrypted packet will be sent via IPv6. Coverity was
complaining that a NULL pointer could be dereferenced. It is unclear
whether that ever would have actually happened, but the updated
expression should quell the warning and should more accurately detect
whether the block for IPv6 should be executed.

bonding lacp: deleting virtual interface which was enslaved may cause crash

Virtual interfaces may be part of the bonding like physical interfaces. The
difference is virtual interfaces may disappear dynamically. As an example,
the following CLI sequence may crash the debug image

create vhost-user socket /tmp/sock1
create bond mode lacp
bond add BondEthernet0 VirtualEthernet0/0/0
delete vhost-user VirtualEhernet0/0/0

Notice the virtual interface is deleted without first doing bond delete.
The proper order is to first remove the slave interface from the bond prior
to deleting the virtual interface as shown below. But we should handle it
anyway.

create vhost-user socket /tmp/sock1
create bond mode lacp
bond add BondEthernet0 VirtualEthernet0/0/0
bond del VirtualEthernet0/0/0 <-----
delete vhost-user VirtualEhernet0/0/0

The fix is to register for VNET_SW_INTERFACE_ADD_DEL_FUNCTION and remove
the slave interface from the bond if the to-be-deleted interface is part of
the bond. We check the interface that it is actually up before we send
the lacp pdu. Up means both hw and sw admin up.

devices: vhost-user crashes displaying show trace for deleted interface

After the trace is collected and if the interface is then deleted, show
trace may crash for the debug image. This is due to the additional check
in pool_elt_at_index() to make sure that the block is not free.

The fix is to do the check in vhost format trace and return "interface deleted"

If an attempt was made to send an IPv6 packet over an IPv4 tunnel,

operations that were allocated. This results in a SEGV when
attempting to dequeue them in dpdk-crypto-input.

Allow IPv6 packets to be sent over a v4 tunnel when using the DPDK
plugin esp crypto nodes.

Adding a prefix to an interface was not permitted if it overlapped

Loosen the restriction. Allow 2 or more addresses from the same
prefix on a single interface. Reference count the prefix to figure
out when a glean/connected route for the prefix needs to be added
or removed.

Added unit tests to check that the route is only removed when all
addresses in the prefix are removed from the interface.

dpdk: initialize rte_mbuf during mempool dequeue

In some cases it may happen that buffer is allocated by DPDK, and freed
by VPP native code. In such cases dpdk metadata is not reset, so we need
to do that during mempool dequeue. Template approach is taken to reduce
cost of that operation.

api: enforce vla is last and fixed string type

Enforce that variable length fields are the last element of API messages.

Add a 'fixed' version of string type, since dealing with
multiple variable length strings turned out too painful
for the C language bindings.

The string type is now:
{
  string name[64]; // NUL terminated C-string. Essentially decays to u8 name[64]
  string name[];   // Variable length string with embedded len field (vl_api_string_t)
};

The latter notation could be made available to other types as well.
e.g.
{
  vl_api_address_t addresses[];
}
instead of

{
  u32 n_addr;
  vl_api_address_t addresses[n_addr];
};

session: allow closed transports to send

Transports like tcp may notify session layer of a close but they may

transports may still want to send packets. So, unless the session has no
transport (transport-deleted state), allow the transport to send.
