The device name is only used by guestfish (when using the -N option to
prepare drives). We constructed the device name very naively,
basically ‘sprintf ("/dev/sd%c", next_drive)’.
This stores the device index instead, and only constructs the device
name in guestfish. Also the device name is constructed properly using
guestfs_int_drive_name so it can cope with #drives > 26.
As a side effect of this change we can remove the extra parameter of
the add_drives macro.

This is the third rewrite of the virt-df program. It very much
follows the outline of the Perl program which this replaced in
libguestfs 1.7.14.
main.c - main program
domains.c - dealing with libvirt, only used if libvirt is around
at compile time
df.c - getting the stats from libguestfs
output.c - writing the output, CSV output
virt-df.h - header file
Note this also uses the shared options parsing code in
'fish/options.[ch]'.
