GRUB has an user-space program emulator that allows to parse config files
and execute boot entries using the kexec tool. Add a grub2-emu subpackage
to install the emulator.
The subpackage is disabled on ppc64le architecture for now since grub2-emu
fails to build there.

The generated menu entries have a --users $grub_users option but this will
fail on old versions of GRUB, since it expects the --users option argument
to either be a constant or a variable that has been set.
The latest GRUB version fix this but the GRUB core isn't updated on a GRUB
package update, so this will cause the entries to not be shown in the menu
after a system upgrade.
Since can cause issues and because the entries that weren't generated from
the BLS snippets didn't have the --users option either, just don't add it.

There was an error in the logic that stored the parsed BLS snippets in the
sorted linked list that is used to populate the GRUB boot menu entries.
Also add a fix found by coverity scan about a possible undefined behaviour
due grub_efi_status_t having the wrong type.

Commit bfc756f8d86 ("Set blsdir if the BLS directory path isn't one of the
looked up by default") attempted to set blsdir if /boot/loader/entries was
not the real path of the directory containing the BLS snippets. Which may
be the case if for example /boot/loader/entries is in a btrfs subvolume.
But in the case of ostree, /boot/loader is a symlink to the directory with
the entries for the current deployment. So with ostree the blsdir will be
wrongly set, since GRUB is able to follow the symlinks just fine. In fact,
it has to follow the symlink since otherwise GRUB will always use the BLS
files for the deployment that the symlink pointed out when blsdir was set.
So only set blsdir if /boot/loader/entries is in a btrfs or zfs partition.

- Limit grub_malloc() on x86_64 to < 31bit addresses, as some devices seem to
have a colossally broken storage controller (or UEFI driver) that can't do
DMA to higher memory addresses, but fails silently.
Resolves: rhbz#1626844 (possibly really resolving it this time.)
- Also integrate Hans's attempt to fix the related error from -54, but do it
the other way around: try the low addresses first and *then* the high one if
the allocation fails. This way we'll get low regions by default, and if
kernel/initramfs don't fit anywhere, it'll try the higher addresses.

- Try to fix things for new compiler madness.
I really don't know why gcc decided __attribute__((packed)) on a "typedef
struct" should imply __attribute__((align (1))) and that it should have a
warning that it does so. The obvious behavior would be to keep the alignment
of the first element unless it's used in another object or type that /also/
hask the packed attribute. Why should it change the default alignment at
all?
