Julian Stecklina 5de0b3e54a stub: rename sections for UKI compatibility
systemd 255 is stricter in what it considers UKIs. It demands .linux
and .initrd sections. Rename our sections that contain the respective
filenames to match these names.

tool: fix atomic write
Atomic write works by first writing a temporary file, then syncing that
temporary file to ensure it is fully on disk before the program can
continue, and in the last step renaming the temporary file to the
target. The middle step was missing, which is likely to lead to a
truncated target file being present after power loss. Add this step.

Furthermore, even with this fix, atomicity is not fully guaranteed,
because FAT32 can become corrupted after power loss due to its design
shortcomings. Even though we cannot really do anything about this case,
adjust the comment to at least acknowledge the situation.

tool: stop most overwriting in the ESP
Since most files (stubs, kernels and initrds) on the ESP are properly
input-addressed or content-addressed now, there is no point in
overwriting them any more. Hence we detect what generations are already
properly installed, and don't reinstall them any more.

This approach leads to two distinct improvements:
* Rollbacks are more reliable, because initrd secrets and stubs do not
  change any more for existing generations (with the necessary exception
  of stubs in case of signature key rotation). In particular, the risk
  of a newer stub breaking (for example, because of bad interactions
  with certain firmware) old and previously working generations is
  avoided.
* Kernels and initrds that are not going to be (re)installed anyway are
  not read and hashed any more. This significantly reduces the I/O and
  CPU time required for the installation process, particularly when
  there is a large number of generations.

The following drawbacks are noted:
* The first time installation is performed after these changes, most of
  the ESP is re-written at a different path; as a result, the disk usage
  increases to roughly the double until the GC is performed.
* If multiple generations share a bare initrd, but have different
  secrets scripts, the final initrds will now be separated, leading to
  increased disk usage. However, this situation should be rare, and the
  previous behavior was arguably incorrect anyway.
* If the files on the ESP are corrupted, running the installation again
  will not overwrite them with the correct versions. Since the files are
  written atomically, this situation should not happen except in case of
  file system corruption, and it is questionable whether overwriting
  really fixes the problem in this case.

tool: make stubs input-addressed
The stubs on the ESP are now input-addressed, where the inputs are the
system toplevel and the public key used for signature. This way, it is
guaranteed that any stub at a given path will boot the desired system,
even in the presence of one of the two edge-cases where it was not
previously guaranteed:
* The latest generation was deleted at one point, and its generation
  number was reused by a different system configuration. This is
  detected because the toplevel will change.
* The secure boot signing key was rotated, so old stubs would not boot
  at all any more. This is detected because the public key will change.

Avoiding these two cases will allow to skip reinstallation of stubs that
are already in place at the correct path.

tool: make kernels and initrds content-addressed
Kernels and initrds on the ESP are now content-addressed. By definition,
it is impossible for two different kernels or initrds to ever end up at
the same place, even in the presence of changing initrd secrets or other
unreproducibility.

The basic advantage of this is that installing the kernel or initrd for
a generation can never break another generation. In turn, this enables
the following two improvements:
* All generations can be installed independently. In particular, the
  installation can be performed in one pass, one generation at a time.
  As a result, the code is significantly simplified, and memory usage
  (due to the temporary files) does not grow with the number of
  generations any more.
* Generations that already have their files in place on the ESP do not
  need to be reinstalled. This will be taken advantage of in a
  subsequent commit.

Raito Bezarius 0107754d62 tool(architecture): make it generic
Architecture is now a generic structure that can be specialized
via an "external" trait for generating the paths you care about
depending on your target bootloader.

Raito Bezarius 609c11f26d tool(systemd-boot): install it once instead of checking for each generation
systemd-boot is now installed once for many generations rather than multiple times.

This means it is not really possible to manage different system in the same "machine", which is a very
obscure usecase, theoretically possible, but not yet encountered.
