The BLS file "linux" and "initrd" fields expect a relative paths from the
root of the partition that contains the kernel and initramfs. The grubby
tool was printing the value of thse fields and not their full path.
So if there is a partition and /boot is a mount point, he BLS would have:
linux /vmlinuz-4.18.0-38.el8.x86_64
initrd /initramfs-4.18.0-38.el8.x86_64.img
And grubby would print:
kernel="/vmlinuz-4.18.0-38.el8.x86_64"
initrd="/initramfs-4.18.0-38.el8.x86_64.img"
But the old tool used to print the full paths of the images, so should be:
kernel="/boot/vmlinuz-4.18.0-38.el8.x86_64"
initrd="/boot/initramfs-4.18.0-38.el8.x86_64.img"

Most bootloaders use the BootLoaderSpec "title" field to name the entries
in their boot menu. The zipl bootloader used the "version" field instead,
since it was wrongly assumed that the zipl boot menu didn't support names
that contained spaces, which are usually present in a BLS "title" field.
But this is not the case, names with space characters are supported by the
IPL and is just a constraint of the section heading in the zipl.conf file.
To be consistent with all the other bootloaders, zipl now uses the "title"
field to populate the boot menu entries from BLS files. So change grubby
to use the "title" field to set the default entry of the "version" field.

The grub2 bootloader expects the BLS linux and initrd fields values to be
set to a relative path to the root of the boot partition and the zipl tool
expects these to be an absolute path to the kernel and initramfs images.
So the grubby wrapper was removing the prefixes from the kernel and initrd
paths before doing any comparision with the BLS fields. But this shouldn't
be done if the /boot directory isn't a mount point.

The BLS files name convention used is ${MACHINE_ID}-${KERNEL_VERSION}.conf
but this means that there can only be a single entry for a given kernel.
Allow the grubby wrapper to add many entries for the same kernel image,
since the old grubby tool was able to do that. To differentiate from the
original BLS entry and to specify that it's a customized entry, add a
[[:digit:]]~custom suffix after the kernel version number.
This will also sort the custom entries before the original entry, that's
also what the old grubby tool did.

For the debug BLS entries a -debug suffix was added so they are sorted after
the kernel entries, but that only works with version sort and not rpm sort.
So instead use ~debug prefix so rpm sort algorithm could sort it correctly.

The wrapper is using the title before to store the default entry, but we
are now using the entry id for grub2, so make the wrapper query the id.

The ! character was used as the delimiter, but this doesn't work when the

The BLS entries use a global kernel command line parameters that's set as
kernelopts variable in the grubenv file. But users may want to have custom
parameters for some entries, so make a copy of the current kernelopts and
set the "options" field value to the modified parameters.

The grubby --info option didn't check if an entry existed for a kernel and
printed wrong information about it. Fix this and also for --update-kernel
and --set-default options that have the same issue.

The grubby wrapper sets the saved_entry in grubenv to the entry title
field since that's done by grubby. But for BLS the id is the filename
without the .conf extension, this saved_entry is set to this when a
new kernel is installed.
So for consistency also use the entry id for the --set-default option.

The script uses sed to modify the options field in the BLS entries, but it
is using a ',' character as the sed delimiter. It's total valid to have a
kernel command line parameter that contains that character, for example:
$ grubby --add-kernel=/boot/vmlinuz --args="console=ttyS0,115200n81" \
--initrd=/boot/initrd.img --make-default --title=install
sed: -e expression #1, char 42: unknown option to `s'
Fix this by using a different delimiter that won't be present in a cmdline.

When a new BLS entry is added, the script checks if the kernel image exists
and also if it was installed from a rpm package. But the latter isn't really
needed, it should be valid to just copy a kernel image and add a BLS entry.

When booting an ppc64 machine on bare-metal (PowerNV) the OPAL firmware
interface is used. The firmware contains the Petitboot boot-loader that
can be used to parse the BootLoaderSpec (BLS) snippets in a BLS setup.
But machines could have an older version of Petitboot that doesn't have
BLS support, so on ppc64 machines can't be assumed that just modifying
the BLS files is enough for those changes to be reflected in the boot
menu. Instead, grub2-mkconfig is executed so the BLS can be parsed and
produce a grub config file that can be used by any Petitboot version.

Add a grubby wrapper script that allows to manage BootLoaderSpec files by
using the same command line options supported by the grubby tool. This is
provided for backward compatibility for grubby users that swtich to BLS.
