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.
It is far too easy to forget to set FWUPD_DEVICE_FLAG_NO_GUID_MATCHING for new
plugins, and without it it all works really well *until* a user has two devices
of the same type installed at the same time and then one 'disappears' for hard
to explain reasons. Typically we only need it for replug anyway!
Explicitly opt-in to this rarely-required behaviour, with the default to just
use the physical and logical IDs. Also document the update behavior for each
plugin to explain why the flag is being used.
This allows you to have two identical Unifying plugged in without one of them
being hidden from the user, at the same time allowing a HIDRAW<->USB transition
when going to and from bootloader and runtime modes.
This removes the workaround added in 99eb3f06b6.

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 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.
This makes perfect sense, because the 'initiator' starts the transaction and
the 'target' is the addressee of the transaction. Even the I²C spec defines the
'master' as 'initiating' the transaction.
This is the same nomenclature now used by the Glasgow project too.
As a consequence, the version number is also set in the event that the silicon
or firmware app-id is not set, which also seems like the right thing to do.
The VID:PID of the device in HPI mode is shared between multiple vendors, and
so we need to use both the silicon ID and the application ID to match specific
firmware updates.
Correctly attach into the alternate mode after the update has completed.
The vendor was appending two files to make LVFS distribution 'easier' but I'd
much rather use the same deliverables as Windows. This also allows us to
simplify the firmware loading.
