[RFA] set/unset/show substitute-path commands (take 2)

[Joel Brobecker <brobecker at adacore dot com>]

Hello,

:ADDPATCH source.c:

Here is a second crack at implementing the substitute-path feature
taking into account all suggestions made so far (hopefully). It also
includes Eli's suggestion to have "show substitute-path FROM".

I have added a first attempt at making a test. It only tests the
manipulation of the list of substitution rules, but not the applying
of them while debugging a program, because I am not sure how to do
that without resorting to shell commands such as mkdir et al. It's
still better than nothing, though.

Documentatio will be revised as soon as the code goes it. It's a waste
of time to have Eli review it if anything during the review changes
the feature in such a way that the documentation needs to be updated.
