alex ca01353df4 feat(boot): make strict mode follow systemd-boot's selection and menu rules
In strict mode a one-shot entry only becomes the default, the default
entry may be one with no boot counter tries left, no menu timeout means a
hidden menu, the menu is shown again when a started image returns, and
entries that mix linux, efi and uki, entries whose file is missing, and
unified kernel images with no name are hidden. Plain EFI entries are not
counted, the XBOOTLDR partition is always read, and a devicetree that
can't be installed fails the entry.

Outside of strict mode these keep working as they did, and each one is
now logged where it applies. The initrd limit of BLS entries is 32.
A devicetree that can't be installed is skipped with a warning.

alex 50f62f5bb6 feat(bls): one entry for each profile of a unified kernel image
A unified kernel image can have several profiles, each started by a
.profile section and made of the sections after it on top of the base.
Every profile is an entry. The first has the id of the file, and the
others add @ and the identifier or the number of the profile, with a
title that names the profile and the profile number as the load options.
The profiles share the boot counter of the file, sort in the order they
are in the image, and a profile after the first is not picked as the
default entry when no default was asked for.

The PE reader keeps every section in order, so repeated names and the
sections that a profile removes can be told apart, and reads images with
more than 96 sections.

alex f4221131f1 feat(bls): boot unified kernel images (Type #2 entries) (#111)
* 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.
