netutils/netcat: implemented NETUTILS_NETCAT_SENDFILE option.
...
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.

netcat_server: do not loop forever
...
To make it similar to other implementations.
(I followed the behavior of NetBSD's nc, which came from OpenBSD.)

netcat: Rewrite the i/o loop
...
* Stop echoing back the input.
It isn't the responsibility of this app, IMO.
* Allow non-text data
* Error checks and cleanups

netcat: Fix a buffer overflow
...
The buffer doesn't have the space for the terminating NUL.
Fix it by replacing it with fwrite, as there seems to be little reason
to use fprintf and NUL-terminated string in the first place.
