[RFC][PATCH 0/2][PR 28406] gdb: add exit command as an alias for quit

[Enze Li <lienze2010@hotmail.com>]

As described in PR28406, I think it is a good idea to add an exit command.
Many years ago, when I used the gdb debugger for the first time, I often
input the "quit" command incorrectly. Adding this "exit" command may be
friendly to new users, regardless of whether they have used other similar
software before.

The specific implementation of this idea is simple, only using the
add_com_alias method. Eventually, the quit_cmd function will be invoked. 

Is this a good idea? Or, do these modifications make sense?
