netlink-socket: Make dumping and doing transactions on same nl_sock safe.
It's not safe to use a single Netlink fd to do multiple operations in an
synchronous way. Some of the limitations are fundamental; for example, the
kernel only supports a single "dump" operation at a time. Others are
limitations imposed by the OVS coding style; for example, our Netlink
library is not callback based, so nothing can be done about incoming
messages that can't be handled immediately. Regardless, in OVS multicast
groups, transactions, and dumps cannot coexist on a single nl_sock.
This is only mildly irritating at the moment, but it will become much worse
later on, when dpif-linux shifts to using Netlink dumps for listing various
kinds of datapath entities. When that happens, a dump will be in progress
in situations where the dpif-linux client might want to do other
operations. For example, it is reasonable for the client to list flows
and, in the middle, look up information on vports mentioned in those flows.
It might be possible to simply ban and avoid such nested operations--I have
not even audited the source tree to find out whether we do anything like
that already--but that seems like an unnecessary cramp on our coding style.
Furthermore, it's difficult to explain and justify without understanding
the implementation.
This patch takes another approach, by improving the Netlink socket library
to avoid artificial constraints. When an operation, or a dump, or joining
a multicast group would cause a problem, this patch makes the library
transparently create a separate Netlink socket. This solves the problem
without putting any onerous restrictions on use.
This commit also slightly simplifies netdev_vport_reset_names(). It had
been written to destroy the dump object before the Netlink socket that it
used, but this is no longer necessary and doing it in the opposite order
saved a few lines of code.

route-table: Handle route updates more robustly.
The kernel does not broadcast rtnetlink route messages in all cases
one would expect. This can cause stale entires to end up in the
route table which may cause incorrect results for
route_table_get_ifindex() queries. This commit causes rtnetlink
route messages to dump the entire route table on the next
route_table_get_ifindex() query.

lib: Simplify rtnetlink routing functionality.
This commit removes the rtnetlink-route module and replaces it with
a much simpler to use route-table module. The route-table uses
rtnetlink to maintain a routing table which may be used to query
the egress interface of particular addresses.
This commit also converts netdev-vport to use the new route-table
module.

debian: Modify ovs-bugtool to include collectd rrd logs
collectd is a utility that stores rrd logs in the directory
/var/lib/collectd/rrd/ by default. rrd logs are created when
collectd is configured to output logs in Round Robin Database
format.
With this change, ovs-bugtool will include collectd logs in the
output bundle from /var/lib/collectd/rrd. The output bundle will
include all sub-directories of the specified collectd directory.
ovs-bugtool checks if a directory exists before it attempts to
include the directory contents in the output bundle. So, running
ovs-bugtool on a system that does not have collectd logs should
not negatively affect the behavior of ovs-bugtool.

ofp-print: Add tests for OpenFlow message formatting.
It's become clear over the past few weeks that some people really depend
on the formatting of ofp-print output. It has also become clear that OVS
doesn't have anything that actually checks or enforces the formatting of
the output. The former is not something I want to encourage, but the
latter is somewhat worrisome because the formatting does change from time
to time and I want to make sure that that is intentional.
So this commit adds at least one test for each supported OpenFlow and
Nicira extension message, so that we can better keep track of changes.

72dfb3b (xenserver: Add LSB init info to scripts.) added LSB init

5.5, but newer versions of XenServer interpret these values and alter
when "openvswitch" gets called. This causes XenServer to not come up
with its networking configuration properly.
By removing the "Required-" parameters, OVS will properly come up. This
is just a temporary fix, and a more proper one will be forthcoming.
