This moves more functionality out of the engine, and will allow us to add some
cleverness to the device list to allow the FuDevice to be shared between
different plugins.
Previously, the various install paths were obtained using get_option
as needed.
This patch unifies the directory selection inside the top-level meson
file as requested in https://github.com/hughsie/colord/pull/62.
This allows us to flash hardware like the Retrode and other devices using chips
like the AT90USB1287.
The test files can be re-generated using the sample code found here:
https://github.com/hughsie/fwupd-test-firmware and are designed
to be used on the AT90USBKEY2 development board.
This makes CI more useful as there is currently a problem with
gcab 0.7 and big endian architectures not yet fixed.

It's actually less scary to see a SHA1 hash than it is to see a path like
/sys/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.2. It's also way easier to
copy and paste into the various fwupdmgr command that require a device ID and
also means we can match a partial prefix much like git allows.
If we also move to a model where plugins can be changed during different stages
of the update (e.g. during detach) then the device might change connection type
and then the sysfs path not only becomes difficult to paste, but incorrect.
Session software doesn't care about the format of the device ID (it is supposed
to be an implementation detail) and so there's no API or ABI break here. A few
plugins also needed to be ported, but nothing too worrying.
This allows end-users testing a specific plugin to start fwupd with an extra
command line parameter, e.g. `--plugin-verbose=unifying` to output a lot of
debugging information to the console for that specific plugin.
This replaces a lot of ad-hoc environment variables with different naming
conventions.
This allows us to do two things:
* Attach after a failed update, so the user isn't left with 'dead' hardware
* Split the detach and attach actions into different plugins in the future
This also allows us to have a separate vfunc to get the new version number
after flashing the firmware, as this may be handled in a different plugin to
the detach phase.
Notably, bootloaders for this class of device export an incorrect DFU interface.
Additionally, allow setting the buffer size for the UPLOAD to a larger size
than the defined device transfer size, which allows us to return the full
packet from the larger XMEGA devices.
Ignoring the warning is not good enough when we're setting policy based on the
specific version. Use the new quirk functionality to do this easily, which
also allows us to remove one more thing in the quirk mega-bitfield.
In the latest version of the LVFS you can restrict the firmware to a specific
machine type, for instance a specific baseboard vendor. This is the same as
done in Microsoft Update using the CHID mechanism.
This commit adds support for the <hardware> requires type, although it needs to
be built against appstream-glib 0.7.4 to be supported and/or tested.
This allows us to remove the Jabra-specific quirk entry in the device bitfield,
and more importantly allows us to support some more Jabra devices in the future
without code changes.
This is slightly more verbose than desired as we also have to include the quirk
information when running the dfu-tool, which does not have an already set-up
FuQuirks object as it has no plugin.
When fwupd is installed in long-term support distros it's very hard to backport
new versions as new hardware is released.
There are several reasons why we can't just include the mapping and quirk
information in the AppStream metadata:
* The extra data is hugely specific to the installed fwupd plugin versions
* The device-id is per-device, and the mapping is usually per-plugin
* Often the information is needed before the FuDevice is created
* There are security implications in allowing plugins to handle new devices
The idea with quirks is that the end user can drop an additional (or replace
an existing) file in a .d director with a simple format and the hardware will
magically start working. This assumes no new quirks are required, as this would
obviously need code changes, but allows us to get most existing devices working
in an easy way without the user compiling anything.
This allows us to fix issues like https://github.com/hughsie/fwupd/issues/265
The data for these was just being generated internally based on the ID and the
basename of the original URI, and that's easy for the calling application to do
itself.
