The only uses of 'af_inet_sock', in both drivers, were ioctls, so it seemed
like a good abstraction to write a function that just does such an ioctl,
and to factor out shared code into socket-util.

These will be used in upcoming commits.
This commit also adds corresponding definitions to the "sparse" header,
so that sparse still works.

Nothing in the tree ever tries to send or receive credentials over a Unix

There are two sensible ways to represent the 6 DSCP bits of an IP
packet. One could represent them as an integer in the range 0 to
63. Or one could represent them as they would appear in the tos
field (0 to 63) << 2. Before this patch, OVS had used the former
method for the DSCP bits in the Queue Table, and the latter for the
DSCP in the Controller and Manager tables. Since the ability to
set DSCP bits in the Controller and Manager tables is so new that
it hasn't been released yet, this patch changes it to use the
existing style employed in the Queue table. Hopefully this should
make the code and configuration less confusing.

The DSCP_INVALID flag allowed callers to prevent socket-util from
modify the DSCP bits of newly created sockets. However, the two
really important callers (implementations of the controller and
manager tables) never used it. Furthermore, the other callers
would be fine always setting the DSCP bits to zero. This patch
removes the DSCP_INVALID option in an effort to simplify the code.

The changes allow the user to specify a separate dscp value for the
controller connection and the manager connection. The value will take
effect on resetting the connections. If no value is specified a default
value of 192 is chosen for each of the connections.

This patch fixes the following compiler warning:

This is equivalent to lookup_ip() except that it accepts DNS names also.

I looked at almost every uint<N>_t in the tree to determine whether it was
really in network byte order, and converted the ones that were.
The only remaining ones, modulo my mistakes, are in openflow.h. I'm not
sure whether we should convert those, because there might be some value
in remaining close to upstream for this header.

Until now, when the poll_loop module's log level was turned up to "debug",
it would log a backtrace of the call stack for the event that caused poll()
to wake up in poll_block(). This was pretty useful from time to time to
find out why ovs-vswitchd was using more CPU than expected, because we
could find out what was causing it to wake up.
But there were some issues. One is simply that the backtrace was printed
as a series of hexadecimal numbers, so GDB or another debugger was needed
to translate it into human-readable format. Compiler optimizations meant
that even the human-readable backtrace wasn't, in my experience, as helpful
as it could have been. And, of course, one needed to have the binary to
interpret the backtrace. When the backtrace couldn't be interpreted or
wasn't meaningful, there was essentially nothing to fall back on.
This commit changes the way that "debug" logging for poll_block() wakeups
works. Instead of logging a backtrace, it logs the source code file name
and line number of the call to a poll_loop function, using __FILE__ and
__LINE__. This is by itself much more meaningful than a sequence of
hexadecimal numbers, since no additional interpretation is necessary. It
can be useful even if the Open vSwitch version is only approximately known.
In addition to the file and line, this commit adds, for wakeups caused by
file descriptors, information about the file descriptor itself: what kind
of file it is (regular file, directory, socket, etc.), the name of the file
(on Linux only), and the local and remote endpoints for socket file
descriptors.
Here are a few examples of the new output format:
932-ms timeout at ../ofproto/in-band.c:507
[POLLIN] on fd 20 (192.168.0.20:35388<->192.168.0.3:6633) at ../lib/stream-fd.c:149
[POLLIN] on fd 7 (FIFO pipe:[48049]) at ../lib/fatal-signal.c:168

If a daemon doesn't start, we need to know why. Being able to
consistently consult the log to find out is helpful.

Provides ability to match over IPv6 traffic in the same manner as IPv4.
Currently, the matching fields include:
- IPv6 source and destination addresses (ipv6_src and ipv6_dst)
- Traffic Class (nw_tos)
- Next Header (nw_proto)
- ICMPv6 Type and Code (icmp_type and icmp_code)
- TCP and UDP Ports over IPv6 (tp_src and tp_dst)
When defining IPv6 rules, the Nicira Extensible Match (NXM) extension to
OVS must be used.

An upcoming commit will add a new user for this function in another file,
so export it and move it to a common library file.

An upcoming commit needs to parse connection strings without connecting to
them, so this change enables that.

In an upcoming commit, another function wants to do the same thing, so

The test-vconn program binds a socket to a nonspecific port number. To
add SSL support to this program, it needs to be able to use SSL, and the
stream library is the easiest way to do that. But the stream library
can't bind to a nonspecific port. This commit adds that feature, by adding
it to the function that the stream SSL library uses as a building block.

The tcp_open_active() and tcp_open_passive() functions don't really have
any strong dependencies on TCP. With a couple of simple changes they
can be used for UDP also. Since this is useful for Netflow, this commit
does so.

The TCP and SSL vconn implementations had a lot of common code to make
and accept TCP connections, which this commit factors out into common
functions in socket-util.c.
Also adds the ability to bind ptcp and pssl vconns to a particular IP
address instead of the wildcard address.
