Remove a few unnecessary headers and unused functions. (#667)

* 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.

Programs using definitions from iperf_config.h (in particular
HAVE_STDINT_H) need to include that header.

Aftermath of #174.

Check HAVE_STDINT_H before trying to include <stdint.h>.

Partial fix for compilation on some Solaris versions. Fixes #175.

Add a few API calls to the client-side example program so we can
exercise recently-added JSON-related functionality.

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).
