Patch for debugapp.in

[Kazunobu Kuriyama]

Hi,

This patch adds the switch --gui[=front_end] to debugapp so that
it can invokes gdb together with your favorite graphical front
end for gdb. The default value is set to ddd.

For example,

$ debugapp --gui <your_application>.debug

invokes gdb with ddd, whereas

$ debugapp --gui=xgdb <your_application>.debug

with xgdb.

Of course, gdb should be 6.0 or higher. Otherwise, a front end
won't display source lists correctly, and thus its use doesn't
make much sense.

I hope some people find it convenient.
