Bug#333423: linphonec doesn't like Ctrl-D

[Martin Samuelsson]

This bug is because linphonec_parse_command_line() is passed a string in
cl even when fgets() in linphonec_main_loop() returns NULL;

A simple fix is attached. It makes the application exit cleanly if
that fgets() return zero, or giving a Ctrl-D alone as a command ends
the program.

There are at least one more fgets() which never gets its return value
checked in linphone_prompt_for_auth_final(). Possibly others.
