chore: Change applicable function arguments from 'char *' to 'const char *' (#1006)

Fixes #946. Should not present any functional changes.

Add --repeating-payload option to the client side (#726)

This option simulates payload in iperf2, which is just repetitive pattern
(ASCII '0..9' repeating), as opposed to iperf3 where payload is random.
It might help in testing and reveal problems in networking gear with hardware
compression (including WiFi access points), where iperf2 and iperf3 perform
differently, just based on payload entropy.

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.

Implement daemon(3) for systems that don't have it.

Fixes (and based on a patch in) #369, with some reworking by @bmah888 and @pprindeville.

Add function declaration for our getline() compat implementation.
Should have been a part of #663, which fixes #607.

Include <sys/select.h> for select(2)

The sys/select.h include is the correct one and fixes building on Android.

See e.g. http://pubs.opengroup.org/onlinepubs/009604599/functions/pselect.html

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.

Fixed bug where -R mode selected on a closed file.

Also added a debugging routine to dump an fd_set.

Show user/system CPU usage as well as total.

Move the JSON initialization/finalization insode the API.

(Mostly) switched error reporting to a single routine that handles JSON mode.

Move non-timer routines from timer.[hc] to iperf_util.[hc]

Got rid of libuuid stuff, for portability.

update license info for all source files

Added support for adding new protocols. Slightly modified iperf_error()

rename uuid.[ch] to iperf_util.[ch] to avoid confusion on some platforms
