The functions were added in f2c4e2b5bd343e06635613e87463b4cabfe98b27 and
implicitly declared in iperf_api.c, but were never actually declared in
the api header file! External users of the api need access to the
declaration in the header file to use the function from the library.

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.

enh: Introduce iperf_set_test_logfile API function (#871)

To be able to set the test->outfile to a different file other than default
if using libiperf API.

Since logfile is now opened in iperf_parse_arguments() and this function
may not be used if running iperf using API, define a dedicated function
iperf_open_logfile() and move the opening of logfile into
iperf_run_client() and iperf_run_server() to make sure logfile will be
opened if iperf_parse_arguments() was not called.
