I recommend just using string_t for now.

Eventually, we need to salvage the string_t disaster (i.e. that string_t
is a fixed-size char array which arbitrarily limits values like
filenames and blows up message sizes).  The annoying thing is that MIG
does support variable-sized character arrays (iirc, the terminology
for the Mach types could be different), so the Hurd could have used it
in the first place.  We could a) simply change it and rebuild clients
and servers, or b) try to provide a smooth upgrade path.
