Ouch. This is not portable to POSIX, and while gnulib can guarantee
that it works, the current gnulib getcwd module is GPL (and relies on
openat, which is a rather heavy-weight replacement!).
I'm going to work on a gnulib module getcwd-lgpl which doesn't fix all
the known bugs in getcwd, but at least guarantees that getcwd(NULL,0)
will malloc insofar as the underlying getcwd is not buggy; we'll need to
import that into libvirt before applying the rest of this patch.
I haven't closely reviewed the rest of this patch yet, but like the
general idea once we have getcwd sorted out.
