# qemu_add_drive_args <index> <args> <filename> <id-name> [<bootindex>]
#
# index: name of the index variable (set to 0 at start)
# args: name of the argument array variable (set to () at start)
# filename: filename of the raw disk image
# id-name: name of the disk in /dev/disk/by-id -> /dev/disk/by-id/ata-disk_$name
# size: optional file size in MiB (0 implies size is not set)
# bootindex: optional bootindex number
#
# to be used later with `qemu … "${args[@]}" …`
# The <index> variable will be incremented each time the function is called.
