* Simplify endianness checks

Linux can be built with too many types of C run-time library and it's
not reasonable to have to enumerate all of them, especially since at
least one of them (MUSL) goes out of its way to not be easily
detectable.

Instead, leverage autoconf better for Linux/BSD to detect either
<endian.h> or <sys/endian.h> directly.

Fix -F problems (#588)

Attempt to fix some brokenness in -F from #301.

In some work related to #125, we introduced a bug in which
chunks of a file being read for the -F option were not
completely sent, particularly with TCP sockets. We attempt
to fix this by detecting cases in which not all data passed
to a socket could be actually sent (for example due to full
socket buffers) and preserving that data for future send
iterations.

The ending statistics in the "diskfile" JSON structure were
wrong, and did not properly distinguish between sender-side
and receiver-side statistics. This has been fixed (at least
for the client side).

Specifically mention in the manpage that "iperf -F" is not
a file transfer tool.

Issue 216 (#581)

* Add configurable timeout for the setup of the control connection.
This is specified using the new --connect-timeout option, with an
integer parameter in ms. The iperf3 client will wait for this
amount of time for the setup of the control connection to the
server. If this option is not given, the OS default for TCP
connection setup is used. Specifying a smaller connection timeout
allows faster detection of a down / unresponsive iperf3 server.

The implementation uses a variation on the timeout_connect()
function from OpenBSD's netcat utility.

Fixes #216.

Normalize socket buffer debugging output, put socket buffer sizes in JSON.

These values show up in the start structure as sock_bufsize (requested
size), sndbuf_actual (actual SO_SNDBUF value) and rcvbuf_actual (actual

Both client and server emit these values in their JSON output for their
respective sides, but don't exchange them.

Add 1KB to default UDP socket buffer sizes under certain circumstances.

This fixes a problem observed on FreeBSD and macOS where the MTU on
the loopback interface is larger than the default socket buffer size.
We adjusted the socket buffer size upwards to match the UDP payload
size, but that's apparently not enough and we ended up dropping packets.
This is bad. Add a 1KB fudge factor, which seesm to avoid this problem.
Affects UDP tests only, not TCP or SCTP.

Issue 496 (#498)

* Dynamically determine an appropriate default UDP send size.

We use the TCP MSS for the control connection as the default UDP
sending length, if the --length parameter is not specified for a
UDP test. This computation replaces the former hard-coded 8K
default, which was way too large for non-jumbo-frame Ethernet
networks.

The concept for this solution was adapted from nuttcp. The
iperf3 implementation is pretty easy since we already were
getting the MSS for the control connection anyway (although we
needed to get it slightly earlier in the setup process to be
useful).

Towards issue #496.

While here, s/int/socklen_t/ in one place to fix a compile warning,
and bump a few copyright dates.

* Warn if doing a UDP test and the socket buffer isn't big enough.

This is surprisingly an issue on FreeBSD and macOS, where the MTU
over the loopback interface is actually larger than the default
UDP socket buffer size. In these cases, doing a UDP test over the
loopback interface (with the new UDP defaults) will fail unless a
smaller --length or a larger --window size is set explicitly.

Linux has larger UDP socket buffers by default (much larger than the
largest possible MTU), but even in the case that the socket buffers
are too small to hold an MTU-sized send, the kernel seems to do the
send correctly anyway.

Still working towards a good solution for issue #496.

* Further refinement on UDP buffer size settings.

If the default buffer size on a UDP test can't hold a packet,
then increase the buffer size to be large enough to hold one
packet payload. (If the buffer size was explicitly set, but too
small to hold a packet payload, then warn but don't change the
buffer size.)

Minor code refactoring to...factor out some common code into
a new iperf_udp_buffercheck() function.

Still working towards issue #496.

Separate out application-level and fair-queueing-based pacing (#488)

* First try to fix pacing issues. Code compiles, lightly run-tested.

Make --bandwidth only control application-level pacing, refecting
behavior of iperf 3.1.2 and earlier.

Add a new --fq-rate that controls only FQ-based per-socket pacing.
A given test can use application-level pacing, FQ pacing, both,
or neither.

Deprecate the --no-fq-socket-pacing option; specifying this generates
a warning and is equivalent to --fq-rate=0.

Towards issue #467 and related to issue #325.

* Move --fq-rate in the help text to be just below --b, tweak wording.

* Sigh. One more tweak on help text.

Some day I probably need to review and rewrite the whole thing.
