This lets iperf work better with multi-homed machines and
VRF.
Fixes#1089.
Based on a patch by Ben Greear <greearb@candelatech.com> via PR #817.

* EXIT_SUCCESS and EXIT_FAILURE are defined in stdlib.h, not sysexits.h
so no need to include the latter.
* No need to include pthread.h.
* Remove the no longer used delay() function.
This also removes the reliance on nanosleep().
* Remove get_tcp_windowsize() and set_tcp_windowsize() which are unused.
These days, iperf uses get/setsockopt() with SO_SNDBUF SO_RCVBUF directly.

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.
Only do -Wall by default if on GCC (or something that looks like
GCC, such as clang/llvm).
Turn on -Werror so we can get some better error-checking, but
we also need -Wno-deprecated-declarations at least for MacOS,
because daemon(3) is deprecated starting with MacOS 10.5.
Fixes#174 (I think).

Revert part of earlier change.
We still want to save the JSON for libiperf consumers that might want it,
but preserve the prior behavior of writing that JSON to stdout. This
maintains (roughly) the behavior of older libiperf, in which libiperf
consumers (such as the iperf3 executable) do not need to explicitly print
the JSON if that's all they're doing with it.

Allow consumers of libiperf3 to get the JSON output for a just-completed test.
This changes the behavior of iperf_json_finish() so that it no longer
outputs JSON output, but saves the rendered output in a NUL-terminated
string buffer. After calling iperf_run_server() or iperf_run_client(),
the client application should check iperf_get_test_json_output() to see
if it returns a non-NULL pointer. If so, there is JSON data available
for it to print or otherwise consume. The buffer is automatically
deallocated when the containing iperf_test structure is deallocated
with iperf_free_test().
Also adds a new API call iperf_get_test_outfile() to find the output
FILE* structure.
Modifies the iperf3 application to use the new API. Users of iperf3
will not notice any functional change.
No effect in "normal" output mode (non-JSON).
