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)

a45a0d37b4 Mention -D, -C, -L in release notes. 
These go to a new section that might be merged with the prior 3.0.0
section pending a release engineering discussion.

Also fix a typo:  s/vebose/verbose/

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.

Slightly tweaked version of a patch that was...

c8a0a2229d Added a check for malloc fail. 
Eventually we need to add a whole bunch more of these.

95360b2046 Show UDP stats in interval reports.

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.
