Limits copying the get version response payload to the size of the out buffer.
Devices that return a larger payload pack the necessary version information at
the beginning of the payload.
Fixes: #1661
More than one person has asked about 'why call fu_plugin_update() for a
reinstall or downgrade' and I didn't have a very good answer.
The plugin API is not officially stable, and we should fix things to be
less confusing. Use the same verbs as the FuDevice vfuncs instead.
The RTD2141B has the same update protocol as RTD2142, but the Chromebook
targets that use it require us to find the drm_dp_aux_dev i2c channel
differently because the AMD display driver doesn't give each output a
unique name in sysfs, so it must be found by walking sysfs from the drm
device representing an output.

Based on a patch by Twain Byrnes <binarynewts@google.com>, many thanks.
Use this to test:
sudo FWUPD_TEST_PLUGIN_XML="<config><delay_decompress_ms>100</delay_decompress_ms></config>" \
./src/fwupdtool --plugins test get-devices -v
Create and destroy /run/lock/power_override/fwupd.lock.
This file will hold the contents of getpid (), which will
stop the device from being suspended while the file exists.
The file will be created and written just before the
update is put into motion and be destroyed once the update
finishes, or upon restart in case of catastrophic failure.

We don't want to show the big warning about the missing ESRT on server
hardware that is managed by a BMC:
WARNING: UEFI capsule updates not available or enabled in firmware setup
See https://github.com/fwupd/fwupd/wiki/PluginFlag:capsules-unsupported for more information.
Applying updates to my new P1G3:
* schedule the update in fwupd
* boot into the BootNext
* apply the capsule with RT->UpdateCapsule
* reboot with RT->ResetSystem
Except the firmware updater EFI binary then wasn't running. The ESRT
last_attempt_status comes back as Success on the reboot.
Disabling the UX capsule made the update apply correctly each and every
time. Until we can work out what models are affected, use a per-vendor
quirk to avoid delaying the release.
This CL moves the battery information retrieval into a new function,
called "fu_plugin_powerd_callback()", which returns the information in a
struct.
This information is then used in fu_plugin_update_prepare() for battery
checks. There is also a g_timeout_add() function being created in
fu_plugin_startup() in order to enable the plugin to repeatedly send a method
call to powerd.
fu_plugin_update_prepare is removed as its functionality is now handled
by src/fu-engine.c
Shim has had a hard time with loading updates from arguments in the
most recent release and this isn't the first time that happened.
Give distros and users an escape hatch that will allow using GRUB
instead.
We should be just checking if the thinklmi plugin inhibited the device,
and if we fix the bug where the last_attempt_status value was not being
read on startup then this test will then fail.
This adds a condition to the powerd plugin that passes updates on devices
that do not give provide valid battery information or whose battery
information is unknown, such as Chromeboxes, which have no battery to
read.
Only the backup BMC device (which we ignore anyway...) can be updated
by specifying the target ID, the others need an *empty* array so that
XCC can work out what devices need to be processed.
Currently the SUCCESS state overrides reboot-needed, thus making the
devices considered for successive git-upgrades within same boot. The
change preserves the REBOOT_NEEDED state. It also added a missed
'changed' signal, which otherwise would skip updating the persistent
state.

Some distributions like RHEL change the default to not autoconnect
ethernet devices. This breaks connecting to the SMBIOS-defined BMC
adapter which means all the reads fail after a 60s timemout.
Autoconnect the internal USB ethernet adapter so we can use Redfish
without user action.
A series of changes are made to the powerd skeleton
plugin in order to reach two goals: ensuring that it handles cases correctly, given certain
information about the battery and/or certain return types and that it
successfully retrieves battery information from powerd to be used later.
Logic is then added to ensure updates are only performed
when that battery level is at or above the minimum threshold.
Then logic is added that checks if the device being updating requires
AC power. Along with this, specific
error statements are added for each scenario where an update is blocked.
To address the next goal, within fu_plugin_startup(), a GDBus connection
is established. However, instead of a direct connection to
powerd, the connection is changed to link to the general system bus with
g_bus_get_sync(). From there, a proxy is created to represent the
connection to powerd. A test call is made for the name of the service that the
proxy represents to check for successful communication.
Then, in fu_plugin_update_prepare(), the existing proxy is called and in the call,
the "GetBatteryState" is passed to make a method call method. The
response is filled into a GVariant, whose entries are initialized in new variables to use
for battery checks. And checks are added to make sure every step was
successful.
