system-traffic: use appropriate nc options for installed version
Test cases using netcat ("ICMP related" and "ICMP related with NAT")
currently fail on systems using the nmap version of nc because this
version does not support the -q command-line option.
Fix this by detecting which version of netcat is is in use and
using the "--send-only" command-line option when the nmap flavor
is detected, and using "-q 1" otherwise (openbsd and traditional
versions).
Tested via "make check-kernel" on RHEL7 (nmap version of nc),
Debian 8.2 (openbsd version of nc), and Ubuntu 14.04 ("traditional" nc).

ofproto-dpif-xlate: Fix recirculation for resubmit to current table.
When recirculation defers actions for processing later, it decides
based on the actions being saved whether it needs to record the table
and cookie from which they originated. Until now, it was thought that
this was only important for actions that send packets to the controller
(because those actions send the table ID and cookie). This overlooked
a special case of the "resubmit" action which also depends on the
current table ID, which meant that this special case malfunctioned if
it came after recirculation. This commit fixes the problem, and adds
a test.

openflow: Better abstract handling of packet-in messages.
Packet-in messages have been a bit of a mess. First, their abstraction
in the form of struct ofputil_packet_in has some fields that are used
in a clear way for incoming and outgoing packet-ins, and others
(packet_len, total_len, buffer_id) have have confusing meanings or
usage pattern depending on their direction.
Second, it's very confusing how a packet-in has both a reason (OFPR_*)
and a miss type (OFPROTO_PACKET_IN_*) and how those add up to the
actual reason that is used "on the wire" for each OpenFlow version (and
even whether the packet-in is sent at all!).
Finally, there's all kind of low-level detail randomly scattered between
connmgr, ofproto-dpif-xlate, and ofp-util.
This commit attempts to clear up some of the confusion. It simplifies
the struct ofputil_packet_in abstraction by removing the members that
didn't have a clear and consistent meaning between incoming and outgoing
packet-ins. It gets rid of OFPROTO_PACKET_IN_*, instead adding a couple
of nonstandard OFPR_* reasons that add up to what OFPROTO_PACKET_IN_*
was meant to say (in what I hope is a clearer way). And it consolidates
the tricky parts into ofp-util, where I hope it will be easier to

ofp-util: Fix OF1.4+ version of ofputil_decode_set_async_config().
The OF1.0 through OF1.3 "set async config" set the whole configuration,
OF1.4+ only update parts of it piecemeal, but the decoding function always
set the whole configuration. This commit fixes the problem by changing the
interface to require the caller to provide an initial state. (It would

ofp-util: Rewrite async config encoding and decoding to be table-driven.
The encoding and decoding of the OpenFlow and Open vSwitch async config
messages was, until now, a collection of disjoint code that had a lot of
redundancy. This commit changes it all to be driven using a single central
table.
This rewrite fixes a bug in the OF1.4+ version of the code, which until
now assumed that every TLV in an OF1.4+ asynchronous configuration message
was exactly 8 bytes long, and reported an error if any was a different
length. This invariant is true of all the standard TLVs already defined,
but it won't be true of any experimenter TLVs (and won't necessarily be
true of any new standard TLVs), so this commit changes it to be more
tolerant.
The OFPACPT_* constants are no longer useful (they are encoded directly
in the table and do not need to be anywhere else), so this removes them.
This commit also adds support for experimenter async config messages.
We don't have any yet but an upcoming commit will add one.

multipart message OFPMP_QUEUE_DESC, which Open vSwitch has not until now

the message is a replacement for the former one, this commit implements it

ofproto: Fix memory leak and memory exhaustion bugs in group_mod.
In handle_group_mod() cases where adding a group failed, nothing freed the
list of buckets, causing a leak. The same was true in every case of
modifying a group. This commit fixes the problem by changing add_group()
to never steal or free the buckets (modify_group() already acted this way)
and then making handle_group_mod() always free the buckets when it's done.
This approach might at first raise objections, because it makes add_group()
copy the buckets instead of just take the existing ones. But it actually
fixes a worse problem too: when OF1.4+ REQUESTFORWARD is enabled, the
group_mod is reused for the request forwarding. Until now, for a group_mod
that adds a new group and that has some buckets, the previous stealing of
buckets in add_group() meant that the group_mod's buckets were no longer
valid; in practice, the list of buckets became linked in a way that
iteration never terminated, which caused memory to be exhausted while
composing the requestforward message. By making add_group() no longer
modify the group_mod, we also fix this problem.
The requestforward test in the testsuite did not find the latter problem
because it only added a group without any buckets. This commit also
updates the testsuite to include a bucket in its group_mod, which would
have found the problem.

python: Stop use of tuple parameter unpacking
Python 3 removed support for tuple parameter unpacking.
https://www.python.org/dev/peps/pep-3113/
Instead of:
def foo((a, b)):
print(a)
print(b)
you should do:
def foo(a_b):
a, b = a_b
print(a)
print(b)
but in both uses here, the values were never used so the fix is even
simpler.

flow: fix compilation of MINIFLOW_ASSERT
Often MINIFLOW_ASSERT is a no-op and compilation of code that uses
it is optimised out. This patch fixes compilation errors that occur
when that is not the case:
* FLOWMAP_MAX does not exist. Use MAP_MAP instead.
* FLOWMAP_IS_SET does not exist. Use flowmap_is_set instead.

1. Create a new function "lldp_destroy_dummy()" because
many structures and its elements, ex: lldp_hardware and lldp_chassis,
are from stack not heap (see test_aa_send). As a result, calling
lldpd_cleanup() is incorrect.
2. Remove lchassis->c_id = xmalloc(ETH_ADDR_LEN);
because it is overwritten at test_aa_send()
3. remove memcpy(&hw->h_lport.p_element.system_id.system_mac,
lchassis->c_id, lchassis->c_id_len);
because the source buf is empty
