There are several subtle bugs in various places in fwupd caused by not treating
user-provided offsets into buffers as unsafe. As fwupd runs as root we have to
assume that all user firmware is evil, and also that devices cannot be trusted.
Make a helper to put all the logic into one place and convert all users.
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
Until now, the unifying plugin was a 'special snowflake' and did things in very
different ways to the other plugins. Refactor each object to derive from either
FuUsbDevice or FuUdevDevice, and then remove LuDevice and the LuContext layers.
