5cdc6a4ac8 Keep track of SACKs and snd_cwnd from tcp_info (Linux only for now).
Committing this WIP so we can get some experimentation done with it.

cfe8c5fb47 Make "iperf3 -s" accept both IPv4 and IPv6 connections on FreeBSD.
(Formerly it was just accepting IPv6.)

The problem here was that FreeBSD by default wasn't allowing IPv4
mapped addresses on IPv6 sockets, whereas other platforms
(specifically Linux and OS X) both do permit this.  We tried to turn
on mapped addresses via a setsockopt(IPV6_V6ONLY) call, but this call
was broken because the level argument was incorrect.  We didn't know
about this because we never checked the return value.

Fix this by providing the correct argument to setsockopt().  Add some
error checking to this and one other setsockopt() call, so we at least
don't fail silently in similar situations.

Issue:		126 (FreeBSD:  iperf3 -s only accepts IPv6
		connections)

d04c7bd0a4 Support setting the IPv6 flow label on Linux systems (only).
This functionality uses some setsockopt(2) calls that unfortunately
don't seem to have an analog on other platforms.

To the extent possible, anyway - on the sender side,
only the packet counts are available.

ba123d5c1e Use setitimer() instead of alarm().
This lets us check timers every tenth second instead of every second,
so we can switch out of the more expensive select() mode even with
the default reporting interval of a second.

fe4a13ab4d Support daemonizing with -D flag.
Possible related work still under consideration:

o Use syslog in daemon mode for output that would normally go to
  stdout / stderr.

o Write a PID file.

This is basically the gist of Issue 105.

ba7b91d26e Changed bug report email to google code link.
Also bumped package id from 3.0a4 to 3.0a5.

This changeset consists of a one-line edit to configure.ac, plus
about fifty kilolines of diffs to a bunch of other config files
generated by bootstrap.sh.

082cbb0ee6 The ctrl_sck does not need to be in the select write_set, and indeed
having it there may cause the select to return immediately every
time. Which is bad, m'kay?

Also, changed the coding idiom used to keep track of the maximum fd
in the fd sets, to be clearer.

d2b9eb1a87 Another potentially protocol-breaking but necessary change.
The error numbers sent for SERVER_ERROR state were declared
as ints, and therefore could be 32 or 64 bits depending on
architecture.  I changed them to be explicitly 32 bits.

This should be the last of these, I've checked out at every network
read/write call and they look ok.

And bumped the version to 3.0-RC5.

4e2ef5070b More sizeof changes.
A couple more sizeof issues found and fixed.  One of them is
actually another protocol change, but due to a fortuitous accident
it should remain compatible with older versions.

Detailed explanation: When a client attempts to connect to a server that
is already busy, the server is supposed to return ACCESS_DENIED as a
state value.  It was doing so, but was writing it as an int, even though
state values are supposed to be signed chars.  The client read the value
correctly as a signed char, getting one byte and throwing away the rest.
So why did this ever work?  Because ACCESS_DENIED is the value -1, and
any byte of an int -1 equals a signed char -1.  If ACCESS_DENIED had been
any other value, this would have been an opvious bug and would have long
since been fixed.  As is, it stuck around working by accident until now.

2944aaa05b State is signed char.
test->state is an explicitly signed char, so the two routines that
manipulate it must use explicitly signed chars too.

One could argue that the two negative state values should have been
positive like the rest, but changing them now would be a protocol change.

3651fa29e2 Bump version.
On further reflection, last night's seemingly trivial change to
the JSON sending/receiving routines is actually a protocol change,
on some machines, and therefore merits a version number change.
