CONFIG_FILE_STREAMS now defaults to 'n' when DEFAULT_SMALL is enabled. This
is a good change, but this source file fails to compile when file streams
are disabled.
Fix this by using dprintf.
Let remote machine handle special character except Ctrl-C, make cu's behavior more close to linux/bsd system.

Previously, if the read bytes were less than the requested, the
file was closed immediately. This behavior, however, does not
consider the fact that the read operation may be blocking when
no bytes are available at the moment. That is true for a named pipe
(FIFO), for instance. Thus, reading it again lets to the underlying
file system the decision of 1) blocking until bytes become
available or 2) return 0 immediately (the case for actual files) or
3) read available bytes.
If the code only change c_oflag, c_iflag and c_lflag, not c_cflag in termios.

Fix https://github.com/apache/nuttx/issues/8731, don't rely on the vt100 to report
the cursor position.
This avoid the implicit input (response of get cursor command) during the user inputs.
Notice: This assume that the nsh prompt is always shown at line start.

Since termcurse will control whole echo and vt100 command itself.
This fix the dupped character in VI's command mode and some display issue in editor mode, like:
```
~
~
~
~
:qq!!
```

Let's echo character by serial driver,
this will imporve the experience of telnetd,
which will display input command and newline twice.
And also enhance the compatiblity with some third party
linux readline based application (like WAMR repl).

Replace all fwrite/fread/fgets/... to write/read/...
Before:
```
text data bss dec hex filename
109827 601 6608 117036 1c92c nuttx/nuttx
```
After:
```
text data bss dec hex filename
108053 601 6608 115262 1c23e nuttx/nuttx
```
After with CONFIG_FILE_STREAM disabled:
```
text data bss dec hex filename
105667 601 6608 112876 1b8ec nuttx/nuttx
```

The old flagging was insufficient, only '\r' was accepted as a line terminator
if CONFIG_EOL_IS_EITHER_CRLF was set.
I noticed this regression after:
