The CustomFlags feature is a bit of a hack where we just join the flags
and store in the device metadata section as a string. This makes it
inefficient to check if just one flag exists as we have to split the
string to a temporary array each time.
Rather than adding to the hack by splitting, appending (if not exists)
then joining again, store the flags in the plugin privdata directly.
This allows us to support negating custom properties (e.g. ~hint) and
also allows quirks to append custom values without duplicating them on
each GUID match, e.g.
[USB\VID_17EF&PID_307F]
Plugin = customflag1
[USB\VID_17EF&PID_307F&HUB_0002]
Flags = customflag2
...would result in customflag1,customflag2 which is the same as you'd
get from an enumerated device flag doing the same thing.
This allows us to 'nest' firmware formats, and removes a ton of duplication.
The aim here is to deprecate FuFirmwareImage -- it's almost always acting
as a 'child' FuFirmware instance, and even copies most of the vfuncs to allow
custom types. If I'm struggling to work out what should be a FuFirmware and
what should be a FuFirmwareImage then a plugin author has no hope.
For simple payloads we were adding bytes into an image and then the image into
a firmware. This gets really messy when most plugins are treating the FuFirmware
*as* the binary firmware file.
The GBytes saved in the FuFirmware would be considered the payload with the
aim of not using FuFirmwareImage in the single-image case.
This means we can use the standard ->set_quirk_kv() vfunc rather than using
FuQuirks directly with a custom group. Also use a plugin prefix for quirk keys.
Devices may want to support more than one protocol, and for some devices
(e.g. Unifying peripherals stuck in bootloader mode) you might not even be able
to query for the correct protocol anyway.
This is typically when the OEM is using the reference hardware design.
Prevent updates, as there might be a new bug introduced in the reference
firmware that only manifests on one OEM's product. It's up to the OEM to do the
testing and validation.
We need something to tie it back to a physical device model if it's using a
reference firmware and we want to update it.
Also split out the firmware parsing to an object so we can check the firmware
using firmware-parse and also fuzz it.

This allows a device subclass to call the parent method after doing an initial
action, or even deliberately not call the *generic* parent method at all.
It also simplifies the plugins; you no longer have to remember what the plugin
is deriving from and accidentally clobber the wrong superclass method.
The end year is legally and functionally redundant, and more importantly causes
cherry-pick conflicts when trying to maintain old branches. Use git for history.
Asking the user for the UID mapping isn't working very well, as it requires lots
of manual handholding. It also doesn't work very well when the device vendor
does not actually have a PCI ID or if the vendor has split into two entities.
Just use the OUI address as an additional VendorID and match any of the device
IDs against any of the metadata-supplied values.
On failure, you get this:
no device found on drm_dp_aux5: Memory query failed: failed to write command
failed to get device after update: failed to wait for detach replug
The FWUPD_INSTALL_FLAG_FORCE flag has really unclear semantics, and ignoring a
file CRC, checksum or model ID should only be done when using fwupdtool actually
debugging a plugin or firmware parser.
Use the existing --force flag when we want a "gentle nudge" like reuploading
previously processed reports.
Print the sysfs path for devices deriving from FuUdevDevice, which also allows
us to use FU_UDEV_DEVICE_DEBUG without monkey-patching the plugins that also
define a device_class->to_string() vfunc.
Although they normally work, some failures have been reported in the field
related to the MST hub not responding in the MST plugin.
When these failures have occurred the dell_dock plugin also fails to
enumerate.
So rather than allow some people who don't have dell_dock compiled to
update their MST hub using synaptics_mst, perform ALL updates for
mst hub via dell_dock.
```
18:06:24:0324 FuPluginSynapticsMST no device found on drm_dp_aux1: VMM5331 inside Dell dock is only supported by dell_dock
```
This flag is used internally by plugins to indicate that they will
skip the phase of firmware installation that power cycles a device.
It is intended to be set by quirks or other environment settings.
Sometimes we only want to add the instance ID to get the quirk matches, and it
is confusing to see the "fake" IDs in the 'fwupdmgr get-devices' output.
If we say that the version format should be the same for the `version_lowest`
and the `version_bootloader` then it does not always make sense to set it at
the same time.
Moving the `version_format` to a standalone first-class property also means it
can be typically be set in the custom device `_init()` function, which means we
don't need to worry about *changing* ther version format as set by the USB and
UDev superclass helpers.
Synaptics versions are encoded as BCD, the largest version that will
ever be represented in this field is '99'.
Using 3 digits in this field has caused multiple problems in upgrades from
LVFS.
1. Devices are being upgraded when not necessary.
IE `5.3.10 > 5.3.010`
2. Device upgrades are deemed failures as follows:
