[Libguestfs] [PATCH V5] NEW API: add new api xfs_info

[Richard W.M. Jones]

You must enable warnings (./configure --enable-gcc-warnings)
and fix all the problems that gcc finds:

cc1: all warnings being treated as errors
make[3]: *** [guestfsd-xfs.o] Error 1

Secondly you have to create the xfs optional group:

    proc_nr = Some 337;
    optional = Some "xfs";
    tests = [

I couldn't test it any further because the warning-as-errors above
stop me from compiling it.
