This will perform updates with all currently present metadata.
It is "intended" for usage with local metadata repositories referring
to local files.
fwupdtool however does also support fetching a file from the web
and if the metadata refers to the file on the web it should also work
for that.
Some firmware has a different on-device checksum to the hash of the firmware
file itself. This may be because:
* The content is not a binary file, e.g. Intel HEX or SREC
* Only part of the firmware is flashed, e.g. ignoring the bootloader section
* The device checksum is calculated using another method entirely, e.g. PCR0
It's also made complicated as there may be more than one 'correct' device
checksum in some cases, but nothing that a union query can't solve.
The LVFS has always sent components with the old-style '<metadata>' section
rather than the new-style '<custom>' section, and when using appstream-glib
we just accepted either element name. Although the LVFS has just been fixed to
use the new name, old metadata might be present on the system already.
When all clients have downloaded new metadata we can revert this, perhaps in a
couple of weeks time. Until then, the belt-and-braces approach is probably a
good idea.

This metadata key is now unnecessary, as firmwares are expected to set the
version format in the metadata.
If the metadata is missing, the LVFS allows a per-vendor default for non-semver
release versions which is now unconditionally set in metadata.
Plugins are allowed to 'opt-out' of this behaviour using _RULE_INHIBITS_IDLE.
This should be used where waking up the hardware to coldplug is expensive,
either from a power consumption point of view, or if other artifacts are going
to be seem -- for instance if the screen flickers when probing display devices.
This functionality is also inhibited when the actual upgrade is happening,
for obvious reasons.
Admins can turn off this auto-sleep behaviour by editing the daemon.conf file.

This speeds up matching for GUIDs by about 90%, taking the query from 3.17ms to
about 0.33ms on my Thinkpad. This is more important for slow ARM hardware,
where strcmp() is more expensive than on x64.
This means we don't have to have all the thousands of GUIDs as tiny allocated
strings being passed around to all plugins in a GPtrArray.
This also reduces our heap usage by about 6%.
These are set from the AppStream metadata and are specific to the firmware
release.
If not provided, the install duration falls back to the per-device duration
values which can be set in the quirk files.
If the FuDevice is changed during a replug then the `UPDATE_STATE_SUCCESS` will
not be stored on the current FuDevice, which means we store an update-state of
`unknown` to the history database.
Which means we get no success or failure reports, which is bad.
This means we are storing the distro that was used to perform the update,
rather than the distro that was used to do the upload.

We want the XML to look like:
<custom>
<value key="fwupd::RemoteId">lvfs</value>
</custom>
not:
<custom>
<fwupd::RemoteId>lvfs</fwupd::RemoteId>
</custom>
Also, fix the XPath query string to actually match the container checksum, and
actually save the custom node to the builder source.
This fixes a regression in 1.2.0 where no reports could be uploaded.
The libxmlb library is much faster to query, and does not require the daemon
to parse the XML metadata at startup. It's a zero-copy mmap design that is more
modern and less clunky.
RSS has reduced from 3Mb (peak 3.61Mb) to 1Mb (peak 1.07Mb) and the startup
time has gone from 280ms to 250ms.
At the moment firmware can declare that it has certain requirements, for
instance the existing firmware version, the bootloader version, or the
vendor ID of the device.
In some situations we actually want to check the firmware version of a
*different* device. Good examples here would be only allowing an EC upgrade if
a specific BIOS update has already been done, or only allowing a wireless
reciever to be updated if the attached wireless devices have been updated first.
To use this, you can do something like:
<requires>
<id compare="ge" version="1.1.3">org.freedesktop.fwupd</id>
<firmware compare="ge" version="0.9.0">guid-of-other-device</firmware>
</requires>
The profiling data is of limited use, and better data can be obtained using
kcachegrind and massif. Additionally, the profile samples were the cause of the
small RSS growth over time, when in reality the data would only be shown when
the verbose switch is used at daemon startup.
Now devices can have multiple GUIDs and do not share platform IDs there is
really no point waiting to add the device.
This allows us to remove a whole lot of code for this now-unused functionality.
It wasn't hugely clear what the platform ID was actually meant to represent. In
some cases it was being used like a physical ID, in others it was a logical ID,
and in others it was both. In some cases it was even used as a sysfs path.
Clear up all the confusion by splitting the platform ID into two parts, an
optional *physical* ID to represent the electrical connection, and an optional
*logical* ID to disambiguate composite devices with the same physical ID.
Also create an explicit sysfs_path getter for FuUdevDevice to make this clear.
This allows WAIT_FOR_REPLUG to always work, rather than depending on the order
that the GUIDs were added, and that the kernel would always return the same
sysfs path (which it doesn't have to do, especially for hidraw devices).
