The GRUB configuration files layout on EFI platforms isn't consistent with
other non-EFI platforms (e.g: legacy BIOS x86 and Open Firmware ppc64le).
On platforms using EFI, the GRUB config file (grub.cfg) and environment
variables block (grubenv) are stored in the EFI System Partition (ESP),
while for non-EFI platforms these are stored in the boot partition (or
/boot directory if not boot partition is used).
The reason for this is that the path where the GRUB bootloader searches
for its configuration file varies depending on the firmware interface.
For EFI the GRUB binary is located in the ESP and it expects to find its
config file in that location as well. But this creates the mentioned
inconsistency, because the GRUB configuration file has to be stored in
/boot/efi/EFI/fedora/grub.cfg while for non-EFI platforms it has to be
stored in /boot/grub2/grub.cfg.
To allow all platforms to have the GRUB config file in the same location,
only a minimal config file could be stored in the ESP and this will load
the one that is stored in /boot/grub2.

GRUB uses -march=i386 to build the x86 BIOS code but recent changes in the
default %{optflags} enabled the -fcf-protection flag that's not compatible
with pre-i686 CPUs.
This led to a build error in the grub2 package. To avoid this failure and
let the package to build again, remove the -fcf-protection flag for now.

The /boot/grub2/grubenv file is not installed by the grub2 packages but
is either a symbolic link created on %install or a regular file created
by Anaconda during installation.
This is causing the tps-rpmtest to fail in some architectures since the
file attributes don't match what's expected by the package. Because is
a special file, make verification to ignore the size, mode, checksum
and mtime attributes.

OSTree doesn't support installations that don't have a boot partition. The
BLS snippets assume that there will be one, so this has to be checked and
only mark GRUB as supporting BLS in OSTree systems have a boot partition.

The Default Boot Behavior for EFI if no BootOrder and Boot#### variables
are found is to look for an ESP and start \EFI\BOOT\BOOT{$arch}.efi.
This is usually fallback.efi installed by the shim package, but since shim
isn't used on armv7, there's no \EFI\BOOT\BOOTARM.EFI installed in the ESP.
So install GRUB as \EFI\BOOT\BOOTARM.EFI for armv7 so there is a default
EFI binary to be started.

Since GRUB 2.04 there is support for TPM measurements in a tpm module that
uses the verifiers framework. So this is used now instead of the previous
downstream patches that we were carrying.
But we forgot to enable this module when rebasing to 2.04 which leads to
GRUB no longer measuring the kernel, initrd and command line parameters.
One side effect of using the verifiers framework is that if measurements
fail, GRUB won't be able to open the files since the errors from the tpm
module are propagated. This means that a firmware with a buggy tpm support
will prevent the machine to boot, which was not the case with the previous
downstream patches. Don't propagate the measurement errors to prevent this.

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.

10_linux.in: fix early exit due error when reading petitboot version

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.

PV and PVH Xen DomU guests boot with pygrub that doesn't have BLS support.
Also Xen Dom0 use the menuentries from 20_linux_xen and not the ones from
10_linux. So BLS support needs to be disabled for both Xen Dom0 and DomU
and use a traditional grub.cfg file generated by the grub2-mkconfig tool.

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.
