* feat(bls): read PE sections without loading the whole image
* feat(bls): produce entries from unified kernel images
* feat(bls): boot unified kernel images as type 2 entries
Scan the EFI/Linux directory, or the new uki-path option of the BLS
generator, for .efi files and turn each one into an entry using the
metadata in its PE sections. Autoconfigure now also detects a disk that
only has unified kernel images. An image with the id of a type 1 entry is
skipped, and boot counting works on the .efi file name.
* fix(boot): rename boot counter files in place instead of copying them
* fix(bls): skip hidden files and keep unified kernel images when the type 1 scan fails
Check file name suffixes without slicing by byte offset, drop the PE
section bytes once an image has been parsed, and only fail the generator
on a type 1 error when unified kernel images are disabled.
* feat(bls): parse and render boot counters
* feat(bls): sort entries with no boot tries left last
* feat(boot): strip boot counters from bls entry ids
* feat(boot): consume bls boot counter tries before booting
* fix(boot): never default to a bad boot counter entry while a good one exists
