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.

The BLS files are copied from /lib/modules/$(uname -r)/bls.conf and this
file has a SELinux label of "system_u:object_r:modules_object_t" like all
the other files that are installed by the kernel package.
But the files in the /boot directory are expected to have a SELinux label
of "system_u:object_r:boot_t". For all the other files that are copied to
/boot by the kernel-install script, the SELinux security contexts are
restored to the default but that was missing for the BLS files.

The btrfs snapshot submenu was removed because it broke the old grubby tool
since it searched for "menuentry". But now that a BLS config is supported,
this can be added again as long as grubby isn't used.
This patch also moves the grub2-probe tool to the tools-minimal package to
prevent a circular dependency since the grub2-tools package depends on the
os-prober package, but os-prober package needs grub2-probe as a dependency.
So instead of making os-prober to depend on grub2-tools, it can be made to
depend on the grub2-tools-minimal subpackage.

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.

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.

This is because while we made the CFLAGS get some new options, LDFLAGS never
got the same treatement, and we disabled %{_hardened_build} to avoid getting
its options in the TARGET_{C,LD}FLAGS variables.
This patch duplicates the infrastructure for {HOST,TARGET}_CFLAGS into
{HOST,TARGET}_LDFLAGS, and adds the %{_hardening_ldflags} and
%{_hardening_cflags} to both HOST_{C,LD}FLAGS.
Additionally, it fixes the CPPFLAGS definitions, since rpm doesn't define any
CPPFLAGS at all, and makes the -I$(pwd) be there exclusively, not on CFLAGS as
well, since they're always used in concert.

There's no point on executing the script if GRUB_ENABLE_BLSCFG has already

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.

os-prober 1.75 dropped all the code for handling device mapper
directly in favor of only supporting the use of grub2-mount.
Thus, we now need grub2-mount to be built and packaged so that
os-prober can depend on it. We ship it in the grub2-tools-minimal
package to avoid creating a dependency loop between grub2-tools and
os-prober.

The GRUB configuration is switched to BLS using the grub2-switch-to-blscfg
script, which is installed by the grub2-tools package. Among other things,
the script copies the blscfg module from the /usr/lib/grub/$arch directory
to /boot/grub2/$arch.
This is done because for non-UEFI installs (i386-pc and powerpc-ieee1275)
the GRUB core and modules aren't updated on package upgrade, so the blscfg
module won't be the latest that contains the current BLS support.
But the grub2-switch-to-blscfg script is currently executed in grub2-tools
%post scritplet, which means that if the grub2-tools package is installed
before the grub2-pc-modules package (that installs the blscfg module), the
grub2-switch-to-blscfg script won't copy the latest version of the module.
This will make systems to fail to populate the GRUB menu, since its config
will already be migrated to BLS but the blscfg module won't be the latest.
So to make sure that the latest blscfg module is copied regardless of the
grub2-tools and grub2-pc-modules packages install order, run the switch
script in a grub2-tools %posttrans so it's executed at the end of the RPM
transaction once all the packages have been installed.

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.

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.

The grub2-efi package create a /boot/grub2/grubenv symlink that points to
/boot/efi/EFI/fedora/grubenv that's where the real grubenv file is looked
up by GRUB on an EFI installation.
But currently if the grub2-efi is installed on a legacy BIOS install, it
will overwrite an existing /boot/grub2/grubenv file with a broken symlink.
So mark it as %config(noreplace) to avoid loosing an existing grubenv.

In rhbz#1638405, we worked around the issue of an existing initramfs
being in the way by removing it if it's older than the kernel we're in
the process of installing.
But it was buggy and only worked with some filesystem layouts and paths, and
also possibly had some issues with file creation times causing the shell -ot
comparison to fail in some cases.
This patch changes it to remove the existing kernel (as well as other
related files) in the case that it's going to do the copy, and also fixes the
path issues.
