This lets iperf work better with multi-homed machines and
VRF.
Fixes#1089.

The netinet/sctp.h header file defines HAVE_SCTP, so we have this
warning while building:
In file included from ../../src/iperf.h:30,
from ../../src/iperf_sctp.c:46:
./iperf_config.h:44: warning: "HAVE_SCTP" redefined
44 | #define HAVE_SCTP 1
|
In file included from ../../src/iperf_sctp.c:43:
/usr/include/netinet/sctp.h:56: note: this is the location of the previous definition
56 | #define HAVE_SCTP
|
This patch replaces our HAVE_SCTP definition with HAVE_SCTP_H to avoid
this warning.

Got the following error when running server side with -B option:
Server side:
./iperf3 -s -B <server_ipv4_address>
-----------------------------------------------------------
Server listening on 5201

iperf3: error - unable to start stream listener: Bad file descriptor

Client side:
./iperf3 -c <server_ipv4_address> --sctp

Another iteration on issue #193, fixes -B with some TCP tests.

Don't count data for tests received after the end of a test.
This prevents is from reporting an incorrect number of bytes
received at the end of the test, which doesn't match up with the
sum of the data received during the test intervals.
Log late receives if debugging mode enabled.
Fixes#692.

Solaris implements an (older?) version of the API for SCTP_MAXSEG,
which takes an integer argument rather than a struct sctp_assoc_val.
We need to test for that and handle it appropriately. There are some
signs it doesn't even work correctly if we do this, so quietly ignore
errors that happen if the OS complains it's unsupported.
Also, Solaris doesn't support SCTP_DISABLE_FRAGMENTS even though it
defines the preprocessor symbol for this. Rather than aborting when
we try to unsuccessfully unset this option, just ignore the error.
Lightly tested with SCTP over IPv6 on localhost.
Contains an alternate implementation of previously-submitted patches
to set the maximum segment size and no-delay options.
As a result of this change, SCTP functionality on Linux will generally
require the libsctp library (on CentOS and similar distributions this
is provided by the lksctp-tools RPM).
Part of #131.

setsockopt(3) returns an error if passing 0 to this option (which
we do if no address family is specified when we bind to the wildcard
address, say by invoking "iperf3 -s" with no other options). This
is because OpenBSD explicitly does not support IPv4-mapped addresses,
so even though the IPV6_V6ONLY socket options exists, it only works
with a non-zero argument.
Fixes#196.
Should fix#177, in which compilation failed on older Solaris systems
that didn't have it. This is a different approach than a patch
suggested in that issue.
Weakly regression-tested on other platforms (test this by specifying
-6, -4, or neither to the server when binding to the wildcard address,
and seeing if a client can connect with various of -6, -4, or neither).
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.
Rather than doing checks for platforms that we believe support SCTP,
instead look for an indication (notably the presence of <netinet/sctp.h>)
that it's supported. This makes the conditionals for SCTP more obvious.
In addition, it opens up the possibility that SCTP might work on some
new OS that's not FreeBSD or Linux.
This change may force some additional build-time requirements on Linux,
such as lksctp-tools-devel on CentOS / Fedora or libsctp-dev on
Ubuntu.
Committing this first cut for review and to enable testing on multiple
platforms. So far this works correctly on Linux (SCTP support) and
MacOS (no SCTP support).
Note this option only has a long option flag; we're running out of
letters for short options.
Based heavily on a patch submitted in Issue 131 (SCTP support for
iperf); I added support for FreeBSD and did some other packaging and
documentation improvements.
We probably shouldn't tie SCTP support to looking specifically for
Linux or FreeBSD; we probably leave support enabled all the time if
possible, possibly with some configure-time checks.
