* 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.

There's usually a top-level header which then includes the sys/

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.

Service Authentication (#517)

Add an optional mode that requires clients to authenticate with the server.

In this mode, clients need to provide a username and a password, which are checked against a password file on the server. The authentication credentials are protected by an RSA public keypair...the encrypted credentials are sent along with the test parameters.

Operationally the use of this feature places the following additional requirements on the build and installation of iperf3:

o The presence of the OpenSSL headers and libraries to build iperf3, and the libraries available on the client and server at runtime.

o Generation of an RSA public keypair; the private part is used by the server and the public part must be distributed to the clients.

o Username/password pairs for all authorized users, to be stored in a file on the server.

o Loose time synchronization between the server and clients (to within approximately 30 seconds).

o Appropriate command-line flags given on the client and server.

Note that iperf3 can be built and run as before, without fulfilling any of these requirements.

Partial documentation for this feature is included in this commit. It is anticipated that additional documentation text and editing will follow this merge.

Submitted by @ralcini. First suggested by @codyhanson in pull request #242.

Add some documentation for fair-queueing per-socket pacing.

For #325.

commit 5571059870f7aefefb574816de70b6406848888f

Change the fair-queueing socket pacing logic in response to feedback.

By default, on platforms where per-socket pacing is available, it
will be used. If not available, iperf3 will fall back to application-
level pacing.

The --no-fq-socket-pacing option can be used to forcibly disable
fair-queueing per-socket pacing. (The earlier --socket-pacing option
has been removed.)

Tested on CentOS 7, more testing on other platforms is required to
be sure it didn't break the old application-level pacing behavior.

For #325.

Checkpoint for initial work on #325 to add socket pacing.

This works only on Linux and depends on the availability of
the SO_MAX_PACING_RATE socket option and the fq queue discipline.
Use --socket-pacing to use SO_MAX_PACING_RATE instead of the
default iperf3 user-level rate limiting; in either case, the
--bandwidth parameter controls the desired rate.

Lightly tested with both --tcp and --udp, normal and --reverse.
Real testing requires analysis of packet timestamps between
multiple hosts.

Fix breakage due to iperf.h depending on the autoconf config.h file but
not including it.

To fix this required us to change config.h to iperf_config.h (to
avoid potential filename collisions with this generic name). Then
iperf.h could include this.

Adjust the existing header file inclusions to track this, and also
canonicalize their inclusion to be at the top of *.c files.
