Some aspects of the method for querying dock firmware do work in 'dell' plugin
but that is not useful for fwupd because it's incomplete.
Due to this the following error shows up in fwupd journal if run on a Dell system
when the new Dell dock is plugged in:
failed to add USB device 0bda:8153: failed to add device using on dell: invalid dock component request Query 3 0 2 4 0
Detect this scenario, and prevent showing errors in logs.
Unfortunately the previous fix (6131f5d) introduced this bug.
The code previously was actually looking for the non-zero case
which was correct, but non-obvious since `efi_guid_cmp` works like
`g_strcmp0` where a match returns zero.
So rather than revert 6131f5d make this completly explicit.
Affected drives should have a prominent statement in the update description,
possibly even the first line so it shows up by default in the updates panel.
Microsoft description about the Status is:
The Status field of the BGRT describes whether the image is currently
displayed on the screen. This is not applicable to the firmware update
display capsule.
Many thanks to Steven Chang for identifying this issue.

Do not unset the quirks when closing the device, the _NO_DFU_RUNTIME quirk is
needed when re-opening the device during detach.
Fixes https://github.com/hughsie/fwupd/issues/927
On any devices that normally would require checking for AC also
check that at least one battery on the system has at least 30% to
perform an update.

Some SKUs of board 4 and later have silicon that will not work with anything
but EC19 or later. So once flashed up to EC19 prohibit downgrades below that
to keep from bricking devices.
This is probably fall out from a previous code re-shuffling.
The EC version is already set elsewhere, and in many cases `self->ec_version`
is `NULL` at this time.
Board 4 was manufactured with package version 89.16.01.00 and this
will prevent properly upgrading between releases. Reset this version
to 00.00.00.00 if detected on this board.
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.
Future metadata from the LVFS will set the protocol the firmware is expected to
use. As vendors love to re-use common terms like DFU for incompatible protocols,
namespace them with the controlling company ID with an approximate reverse DNS
namespace.
This also allows more than one plugin to define support for the same protocol,
for instance rts54hid+rts54hub and synapticsmst+dell-dock.
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.
