[Libguestfs] [nbdkit PATCH 0/3] Fix %m usage on BSD

Our use of "%m" in various error messages is testament to the project's initial life on Linux - but other than Cygwin, I know of no other platforms supporting that glibc extension. We COULD audit the code and manually turn "%m" into "%s"/strerror(errno), but that's a lot of churn. Instead, let's fix the few outliers that can't be easily wrapped, then wrap the remainder. While I was able to test this on Linux (both that no wrapper is used by default, and that faking that %m fails causes the wrapper to do the right thing), I haven't actually tried it on a BSD box, hence I'll wait for review before pushing.
