eo_step gdb script installation to help debugging of applications by

stepping over Eo.
To do it:
- Write in ~/.gdbinit "source prefix/share/eo/eo_step.py" (prefix is usually/opt/e17)
- in gdb, when arriving to eo_function (eo_do, eo_do_super), execute
eo_step. This script will step into the code until it reaches a function
that doesn't belong to libeo.

Because of a bug in gdb that will be fixed in 7.6, if after having used the
script once, you rerun your application and reexecute the script, a
segmentation fault can occur. Sorry for the inconvenience.
