bf72d393fd Split up FuUsbDevice into ->open() and ->setup()
Before this change calling FuUsbDevice->open() opened the device, and
also unconditionally added various GUIDs and InstanceIDs which we
normally do in setup.
Then fu_device_setup() would call the FuSubclass->setup() vfunc which
would have no way of either opting out of the FuUsbDevice->setup()-like
behaviour, or controlling if the parent class ->setup is run before or
after the subclass setup.

Split up FuUsbDevice->open() into clear ->open() and ->setup() phases
and add the parent class calls where appropriate.

This means that ->setup() now behaves the same as all the other vfuncs.

2e1245728f Call the superclass directly from subclassed devices
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.

5c9b1fcc81 Only include the start year in the copyright header
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.

f50ff2c27e Decouple the version format from the version itself
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.

5079f26f0e Never guess the version format from the version string
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

ff704414f6 Use superclassed versions of FuDevice when calling udev_added() and usb_added()
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.

1263446b23 trivial: Add a 'setup' vfunc that is used after open()
The setup() is the counterpart to probe(), the difference being the former needs
the device open and the latter does not.

This allows objects that derive from FuDevice, and use FuDeviceLocker to use
open() and close() without worrying about the performance implications of
probing the hardware, i.e. open() now simply opens a file or device.

87fb9ff447 Change the quirk file structure to be more efficient
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.
