Richard Hughes 7bcb8d4385 Export FwupdPlugin so we can convey enumerated system errors to the end user 
For instance, we can tell the user that UEFI UpdateCapsule is disabled in the
system firmware, or that efivarfs is not mounted. This is much better than
creating "dummy" devices which are really just hacks around the problem because
no better API existed. THe dummy devices cause as many problems as they solve.

Plugins have to set FWUPD_PLUGIN_FLAG_USER_WARNING if a warning should be shown
to the user, and only one warning will be shown of each failure type.

It is expected that GUI clients like gnome-software and gnome-firmware would use
this API to notify the user the localized message for why firmware updates are
not being shown.

TPM Event Log Support

Introduction

The TPM Event Log records which events are registered for the PCR0 hash, which may help in explaining why PCR0 values are differing for some firmware.

The device exposed is not upgradable in any way and is just for debugging. The created device will be a child device of the system TPM device, which may or may not be upgradable.

Vendor ID Security

The device is not upgradable and thus requires no vendor ID set.
