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.
It appears to only happen on non-dell systems trying to look up system
ID through `sysinfo_get_dell_system_id`
Other than CI non-dell systems won't be running this code.
There are some packaging problems in some distributions that lead
to TSS stack emitting warnings that will fail self tests.
These don't occur as root, and furthermore those distributions run
CI as root already.
And in the dell plugin make it non-fatal to have TPM register read failures
in case the system has TPM1.2 not TPM2.0
These are a more scalable way to apply firmware across a variety of
platforms.
An example:
```

This removes the 'two-layer' FuDevice and FuSyanpticsmstDevice model, where
a complicated plugin cache was used to add and remove devices to the daemon.
By making FuSynapticsmstDevice derive from FuDevice rather than GObject we can
also use a lot of the helper functionality like the other plugins, for instance
->prepare_firmware().
The `drm_dp_aux_dev` devices do not emit uevents on unplug/re-plug and so all
devices of `drm` class are watched and the actual DP AUX devices rescanned after
a small delay. When the AUX devices emit changes from the kernel this workaround
can be removed.
Also drop force power support for MST controllers in the Dell plugin. Overall
this has just led to more problems than it's helped.
* Monitor flickers when turned on
* Crashing graphics drivers from time to time
* Fragile logic that doesn't always represent the device state
This difficult to debug bug only showed up when the fwupd service was stopped,
which the user never noticed, but services like abrt were still keen to report.
The root issue was that the call to fu_plugin_get_smbios_data() in
fu-plugin-uefi.c:fu_plugin_startup() was freeing the returned const GBytes,
which rippled down all the way to a double-free deep in libxmlb.
It's somewhat unusual to have a const GBytes, so just change the plugin helper
to returned a ref'd copy, on the logic a potential 16 byte memory leak is better
than a double-free when the next plugin gets the logic the wrong way around.

This leads to madness, as some formats are supersets of the detected types,
e.g. 'intel-me' is detected as 'quad' and 'bcd' is detected as 'pair'.
Where the version format is defined in a specification or hardcoded in the
source use a hardcoded enum value, otherwise use a quirk override.
Additionally, warn if the version does not match the defined version format
This also allows us to write mixed-endian structures and adds tests. As part of
this commit we've also changed the API of something that's not yet been in any
tarball release, so no pitchforks please.
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.
Since it matches the Realtek dongle, shouldn't show this error:
failed to add USB device 0bda:8153: no dock detected
All the time when that dongle is plugged in
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).
The daemon creates a baseclass of either FuUsbDevice or FuUdevDevice when the
devices are added or coldplugged to match the quirk database and to find out
what plugin to run.
This is proxied to plugins, but they are given the GUsbDevice or GUdevDevice and
the FuDevice is just thrown away. Most plugins either use a FuUsbDevice or
superclassed version like FuNvmeDevice and so we re-create the FuDevice, re-probe
the hardware, re-query the quirk database and then return this to the daemon.
In some cases, plugins actually probe the hardware three times (!) by creating
a FuUsbDevice to get the quirks, so that the plugin knows what kind of
superclass to create, which then itself probes the hardware again.
Passing the temporary FuDevice to the plugins means that the simplest ones can
just fu_plugin_device_add() the passed in object, or create a superclass and
incorporate the actual GUsbDevice and all the GUIDs.
This breaks internal plugin API but speeds up startup substantially and deletes
a lot of code.
1) Switch to daemon provided vfuncs for USB
2) Set quirks so that the plugin only runs when Realtek NIC shows up
3) Rely on the daemon to process all removals by parent tree
As seen by recent testing this is not working every time.
Since e6cda81f we're now building GUIDs that represent all the possibilities
for shared parts so it's not important to set dock type.
This pivots the data storage so that the group is used as the preconditon
and the key name is used as the parameter to change. This allows a more natural
data flow, where a new device needs one new group and a few few keys, rather
than multiple groups, each with one key.
This also allows us to remove the key globbing when matching the version format
which is often a source of confusion.
Whilst changing all the quirk files, change the key prefixes to be more familiar
to Windows users (e.g. Hwid -> Smbios, and FuUsbDevice -> DeviceInstanceId)
who have to use the same IDs in Windows Update.
This also allows us to pre-match the desired plugin, rather than calling the
probe() function on each plugin.
If the daemon either de-duplicates or replaces the object passed emitted from
device-added then the object set as the alternate may not be the same instance
as the daemon version. This causes weird things to happen.
To make this less fragile, specify the *ID* of the object that should be the
alternate device, which allows the daemon to do clever things, and then assign
the object from the ID as the last step.
Although fixing no bug, this makes implementing future functionality easier.
