This drops the requirement on us being so strict on a particular ABI version,
and also more strongly discourages out of tree plugin development.
We should still strive to keep API stable, and as such keep a symbol map still.
Use rpath instead for the static plugins, and set the plugin install directory
to just fwupd-$ABI$ as we're storing more than just plugins here now.
Saving the quirks in the GResource section worked well, but it made the build
system very complicated and also meant the .data section was duplicated in
both `fwupd` and `fwupdtool` -- negating a lot of the hard-fought savings.
Simplify this feature so that we just `cat` all the quirk files together, then
gzip them into a single file. This means that at startup fwupd only needs to
check the mtime of one file, and weirdly it's actually faster to load a smaller
compressed file from disk that it is to load multiple uncompressed files.
tristate features will automatically disable if dependencies marked
as required are missing.
Packagers can manually override using `auto_features`.

The I²C proxy specification is not always shared with all other devices as
I originally hoped, instead there are other legacy devices that use different
sets of I²C commands.
Un-share various bits of code to allow for additional I²C devices to be added.
No logic changes.
