For interfaces which are slave links to a bounded interface, do not
allow sub-interface creation nor interface state to be changed.
Change "show interface" to display interface state as "bond-slave"
for slave links to a bonded interface.
Change "show hardware" to support a "bond" keyword and display slave
links to a bonded interface.

Control Plane
-------------
In essence, this introduces basic support for map-request/reply
processing, the logic to generate and consume such messages, including
SMRs, a control-plane backend, consisting of an eid-table, locator and
locator-set tables, and CLI to interact with it. Naturally, we can now
serialize/deserialize LISP specific types: addresses, locators,
mappings, messages. An important caveat is that IPv6 support is not
complete, both for EIDs and RLOCs.
Functionally, the DP forwards all packets it can't handle to the CP
(lisp_cp_lookup node) which takes care of obtaining a mapping for the
packet's destination from a pre-configured map-resolver using the LISP
protocol. The CP then caches this information and programs the DP such
that all new packets with the same destination (or within the covering
prefix) are encapsulated to one of the locators retrieved in the
mapping. Ingress traffic-engineering is not yet supported.
Data Plane
----------
First of all, to enable punting to the CP, when LISP GPE is turned on a
default route that points to lisp_cp_lookup is now inserted. The DP
also exposes an API the CP can use to program forwarding for a given
mapping. This mainly consists in allocating a tunnel and programming the
FIB such that all packets destined to the mapping's prefix are forwarded
to a lisp-gpe encapsulating node.
Another important change done for lisp forwarding is that both source
and destination IP addresses are considered when encapsulating a packet.
To this end, a new FIB/mtrie is introduced as a second stage, src
lookup, post dst lookup. The latter is still done in the IP FIB but for
source-dest entries, in the dest adjacency the lookup_next_index points
to a lisp lookup node and the rewrite_header.sw_if_index points to the
src FIB. This is read by the lisp lookup node which then walks the src
mtrie, finds the associated adjacency, marks the buffer with the index
and forwards the packet to the appropriate next node (typically,
lisp-gpe-encap).

This patch defines a new l2input feature: l2-rw
It makes use of vnet_classify in order to match
packets and applies mask/value changes depending
on the matched classify entry.

The check for input sw_if_index against output sw_if_index is not correct
for the interface on the replication order after VXLAN tunnel because the
encap code overwrite packet sw_if_index[VLIB_RX] with that of the VXLAN
tunnel sw_if_index. The check should be done using sw_if_index[VLIB_RX]
saved in the packet context.

tapcli interfaces were creating single-packet frames.
It now calls readv until the frame is full, or
readv returns error EAGAIN.
This is usefull when a significant amount of traffic
flows through tap interfaces.
This patch also fixes a memory leak by correctly
initializing b->clone_count to zero.

classifier used to crash when packet data was not aligned.
This commit also includes:
- writer lock initialization bugfix
- CLI help was missing opaque-index
- ip_input_acl was applying the mask on buffer->data instead of packet head
On a side note, my tests failed to show any improvements
when using SSE. Further tests might be interesting to see if they
actually perform better.

...
Looking at vlib_node_registration_t, I think the reason is that
the char * next_nodes[] could be bigger where the variable is defined
in .c file.
We should mark global variables as external in header files.
Some of them can be made static.

In case socket-mem was set to <1024 and no 1G page long hupepages were
available, the condition was evaluated in unexpected manner. In other
words use_1g == 1, and that fails later in mount().
This patch makes sure this is prevented - if there are no pages_available,
do not even try to use that pagesize.

Both ARP and NDP need to be called when hi->output_node_index is changed.
It does not look like a perfect solution though. Maybe an actual up-down
