make -C examples causes several errors and warnings.
And I read and executed each sample code and found some issues.
The attached diff file includes fixes for them.
Thanks.
--------------------------------------------
excallback.c
This code was contributed for readline-4.0.
change_prompt() can be implemented using rl_set_prompt(), introduced by readline-4.2.
I have updated it to allow selection by rl_readline_version.
The code to save and restore terminal settings can be removed by using rl_callback_handler_remove().
I have made it selectable with the USE_RL_CALLBACK_HANDLER_REMOVE macro.

rl-callbacktest.c
Fixed to be consistent with the sample code in "2.4.14 Alternative Interface Examples".
In addition, this modification simplifies the comparison of this code with rl-callbacktest3.c.
