enh: Add --rcv-timeout option (#1125)

Enhancement to PR #1101 - add --rcv-timeout option to allow setting the timeout for receiving packet from the sender in a running test, instead of the constant 120 seconds set in #1101. This is to allow short timeout, so the server will not be "busy" for long time doing nothing. Also, the resolution is set to ms (with minimum of 100ms), as at least in fast networks that may be required.

Since both the server and the client can be a sender, the option is allowed for both. The server setting is for all tests - the client is not sending its --rcv-timeout setting to the server.

While changing the help message, few printf constants from other help lines were changed to parameters.

fix (tcp): Fix behavior with partial sends when using -k with TCP (#1082)

We now only count an attempted send once all of its bytes are sent
(and will perform partial sends if necessary to finish sending all the bytes).
Previously, partial sends were counted as completed, for the purpose
of the -k option.

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.

Fix some compile-time warnings on macOS (#671)

* Attempt to quiet a warning with print(3) formatting. As a part of this, factor out PRIu64 support / compatibility (added in #664) into a header file and make it more portable by taking into account the size of a long integer. Based on email conversation with: @pprindeville.

* Follow-up to pull request #669, fixing compiler warnings on platforms that don't have HAVE_TCP_CONGESTION defined.
