This allows us to 'nest' firmware formats, and removes a ton of duplication.
The aim here is to deprecate FuFirmwareImage -- it's almost always acting
as a 'child' FuFirmware instance, and even copies most of the vfuncs to allow
custom types. If I'm struggling to work out what should be a FuFirmware and
what should be a FuFirmwareImage then a plugin author has no hope.
For simple payloads we were adding bytes into an image and then the image into
a firmware. This gets really messy when most plugins are treating the FuFirmware
*as* the binary firmware file.
The GBytes saved in the FuFirmware would be considered the payload with the
aim of not using FuFirmwareImage in the single-image case.
Keeping *internal* API and ABI compatibility makes working with an already
complex codebase more mentally demanding than it needs to be.
Remember: plugins should be in-tree and upstream! If your out of tree plugin
stops working then it should be upstream.
The public-facing libfwupd will remain API and ABI stable for obvious reasons.
When using "objcopy -O binary" to generate AArch64 EFI images, it
silently drops the sections without "alloc" or "load" or the sections
with "unload", and this caused the content of .sbat was skipped in the
final EFI image.
This commit sets the common read-only data section flags to .sbat to
make sure the content will be copied.

We want to make it as easy as possible for devices to refuse to update on low
battery, as this will likely be one of the WWCB requirements.
Ideally devices will check the battery level inside the firmware, but by also
providing the battery level to fwupd we can give the user a warning *before*
the update has started and without switching the device into bootloader mode.
Rather than trying to guess typos, force each plugin to register the quirk
keys it supports, so we can show a sensible warning if required at startup on
the console.
The best way of not getting something wrong is to not require it in the first
place...
All plugins now use DeviceInstanceId-style quirk matches and we can just drop
the prefix in all files. We were treating HwId=, Guid= and DeviceInstanceId= in
exactly the same way -- they're just converted to GUIDs when building the silo!
This means we can use the standard ->set_quirk_kv() vfunc rather than using
FuQuirks directly with a custom group. Also use a plugin prefix for quirk keys.
At the moment plugins are doing this a few different ways; either looping
through the HwIds manually (e.g. flashrom) or setting a custom flag that is
checked in fu_plugin_setup (e.g. uefi-recovery).
Define a standard 'Plugin' HwId quirk to simplify plugins.
