85307c34e8 loopback: Do not automaticaly replace existing loopback dev, error instead
If there is a loopback device with the same name as the one to be created,
instead of closing the old one and replacing it with the new one, return an
error instead. If the loopback device was created, its probably being used
by something and just replacing it may cause GRUB to crash unexpectedly.
This fixes obvious problems like "loopback d (d)/somefile". Its not too
onerous to force the user to delete the loopback first with the "-d" switch.

384091967d Rename grub_disk members
Otherwise it horribly clashes with gnulib when it's
replacing open/write/read/close

ca0a4f689a verifiers: File type for fine-grained signature-verification controlling
Let's provide file type info to the I/O layer. This way verifiers
framework and its users will be able to differentiate files and verify
only required ones.

This is preparatory patch.

8ae6704517 * grub-core/disk/loopback.c: Use sequential IDs rather than pointer.
In case of quick removal of loopback and adding another one it may
	get same ID, confusing the cache system.
