This option enables using sendfile() in netcat client mode
if a normal file (not stdin) is sent. If the option is enabled
but stdin is sent rather than a normal file, netcat falls back
to the combination of read() and write().
Using sendfile() provides a higher performance compared to
the combination of read() and write().
Also this option is useful for testing / debugging tcp_sendfile()
functionality of NuttX TCP/IP stack.
The logic changes are as follows:
1、Loop sending the DISCOVER up to CONFIG_NETUTILS_DHCPC_RETRIES times
and exit if failure
2、Loop sending the REQUEST up to CONFIG_NETUTILS_DHCPC_RETRIES times
and exit if failure

* webclient_perform
* Add a new flag to use non-blocking mode (WEBCLIENT_FLAG_NON_BLOCKING)
* Implement restarting
* Add a few associated API functions
* webclient_get_poll_info: get the descriptor info for poll/select
* webclient_abort: abort the operation (instead of restarting)
- check for minimum packet length (44 bytes, which includes the fields we
read next)
- pass the correct remaining buffer length to dhcpc_parseoptions()
- dhcpc_parseoptions(): ensure we never read past the end of the buffer

It matches the original iperf behavior.
Note: -t is a client-only option for the original iperf 2.xx.
Note: You can still choose the previous behavior by
explictly specifying -t.

Similarly to the fix in wget_parseheaders.
But simply always bail out as i guess it's very rare to see
that long status line.
Tested with an aritifically small CONFIG_WEBCLIENT_MAXHTTPLINE=20,
which is smaller than "HTTP/1.1 301 Moved Permanently".
* Detect a long header line which doesn't fit the buffer.
* If the header line in question doesn't seem important for us,
just ignore it.
* Otherwise, bail out with -E2BIG.
The overrun was found by LLVM UBSan on macOS.
The following is an example of a long header line,
which doesn't fit the default CONFIG_WEBCLIENT_MAXHTTPLINE=200.
