Store cmdline in BLS snippets instead of using a grubenv variable
The kernel cmdline was stored as a kernelopts variable in the grubenv file
and the BLS snippets used that. But this turned out to be fragile since the
grubenv file could be removed or get corrupted easily.

To prevent the entries to not have a cmdline if the grubenv can't be read,
a fallback variable was set in the GRUB config file. But this still caused
issues since the config needs to be re-generated to change the parameters.

Instead, let's store the cmdline in the BLS snippets. This will make the
configuration more robust, since it will work even without the grubenv
file and the BLS entries will contain all the information needed to boot.

Drop 10_linux_bls and avoid corner case of blsdir set with ostree
The logic to parse the BLS configs to generate a set of menuentry commands
that's needed on ppc64le machines with bootloaders that don't have support
to parse BLS config directly, was implemented in a 10_linux_bls script.

But there's no need to have a separate script just for this and this logic
can be merged into the 10_linux script to avoid code duplication.

Also since the blscfg module will also now be used by ostree-based distros
there is a possible corner case in which a user set the blsdir variable to
a BLS directory path that is different than the default used by ostree.

So to avoid possible issues, only drop the marker file to specify that the
bootloader has support to parse BLS files if this variable hasn't been set.

Update to grub 2.04
This change updates grub to the 2.04 release. The new release changed how
grub is built, so the bootstrap and bootstrap.conf files have to be added
to the dist-git. Also, the gitignore file changed so it has to be updated.

Since the patches have been forward ported to 2.04, there's no need for a
logic to maintain a patch with the delta between the release and the grub
master branch. So the release-to-master.patch is dropped and no longer is
updated by the do-rebase script.

Also since gnulib isn't part of the grub repository anymore and cloned by
the boostrap tool, a gnulib tarball is included as other source file and
copied before calling the bootstrap tool. That way grub can be built even
in builders that only have access to the sources lookaside cache.

Cleanup our patchset to reduce the number of patches
This change reorganizes and cleanups our patches to reduce the patch number
from 314 patches to 187. That's achieved by dropping patches that are later
reverted and squashing fixes for earlier patches that introduced features.

There are no code changes and the diff with upstream is the same before and
after the cleanup. Having fewer patches makes easier to manage the patchset
and also will ease to rebase them on top of the latest grub-2.04 release.

Enable again multiboot and multiboot2 modules on EFI builds
Building the multiboot and multiboot2 modules was disabled for EFI builds.
But that made the menu entries created by the Xen package to stop working
since they use the multiboot2 module.

The modules were disabled modules because they can be used to bypass the
Secure Boot mechanism. But it's enough to not include these modules in the
grub2 EFI binary that's signed, which is the case already in the grub2 pkg.

Having them as modules if the user installs the grub2-efi-x64-modules is
a valid use case. And since module loading isn't allowed when Secure Boot
is enabled, it doesn't represent any security threat.

Make blscfg module compatible at least up to the Fedora 19 GRUB core
The blscfg module isn't compatible with the GRUB core.img installed by any
release older than Fedora 21.

This is because the blscfg module calls to the grub_file_size() function to
check if the BLS file size is correct, but the struct grub_file used as the
parameter for this function changed in the GRUB version used in Fedora 21.

So the function returns a wrong file size due the .size field offset being
different in the older GRUB from Fedora 20 and earlier.

This is causing all the BLS files to be ignored due having a wrong size and
leading to GRUB menu not being populated on boot.

10_linux_bls: don't add --users option to generated menu entries
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.

Only set blsdir if /boot/loader/entries is in a btrfs or zfs partition
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.
