* Of course, since Grub4DOS's grldr.mbr hasn't changed from previous releases
there's not much to update there, but then again, people like version bumps.
* GRUB have cherry-picked patches from the "BootHole" vulnerability fix at
https://lists.gnu.org/archive/html/grub-devel/2020-07/msg00034.html and
have applied them to their 2.04 GRUB loader.
* This results in breakage with "error: symbol 'grub_calloc' not found" when
using the release GRUB 2.04 version of core.img.
* Therefore, we too cherry-picked some patches to apply on top of GRUB 2.04
release to make our core.img compatible with Ubuntu 20.10.
* Closes#1616
* Also increase the maximum write stride for ms-sys to 64 KB (required to
write the GRUB 2.05 bootloader which is larger than 32 KB) and update hash DB.
* Also fix Grub4DOS and Grub2.0 versioning issues
* Also ensures that operation gets canceled on missing download
* Also fix German translation and remove trailing whitespaces in .loc file
* Also fix inverted display status for VMWare disk detection
