b56015ed3f uefi: Add the PCR0 value as the device checksum for system firmware
We can't actually access the UEFI ROM from userspace, but the PCR0 is a hash
built from the ROM itself. We could use this value to ensure the firmware has
been written correctly, and that the PCR0 matches the expected value specified
in the metadata.

8612318158 uefi: When adding headers set the header size to 4k
This solves issues with implementations that require 4k alignment
of pages in BIOS which is seen on certain architectures.

The UEFI spec prescribes that the "minimum" size is the size of
the EFI header but that this may be increased up to larger sizes
due to extended header entries.

2ac3aca2a7 uefi: Append the header on capsules without headers from Linux
This allows using better heuristics and potentially phasing this out
in the future.

a0da340b60 uefi: Do not add devices with invalid GUIDs
Note: We deliberately don't add the device without 'UPDATABLE' as there's
nothing the user can actually do to repair this themselves.

ce712426f8 uefi: Set the quirks on created devices
Ensure the quirk object is set, and then add the GUIDs first so that the
version format can be set from a quirk file.

Additionally, only overwrite the fallback name if the name has not already been
set manually from a quirk.

c125ec02ed Clarify what the platform ID actually is by renaming it
It wasn't hugely clear what the platform ID was actually meant to represent. In
some cases it was being used like a physical ID, in others it was a logical ID,
and in others it was both. In some cases it was even used as a sysfs path.

Clear up all the confusion by splitting the platform ID into two parts, an
optional *physical* ID to represent the electrical connection, and an optional
*logical* ID to disambiguate composite devices with the same physical ID.

Also create an explicit sysfs_path getter for FuUdevDevice to make this clear.

This allows WAIT_FOR_REPLUG to always work, rather than depending on the order
that the GUIDs were added, and that the kernel would always return the same
sysfs path (which it doesn't have to do, especially for hidraw devices).

29129ed4f4 uefi: Allow upgrades using a self-signed fwupd.efi binary
This doesn't require shim, so for this uncommon case add a configure option.

fwupdate prefix is used by fwupdate and this will prevent clashes in case
its used instead.

This will prevent potentially clashing with fwupdate's EFI application
and allow them to remain co-installable.
