Richard Hughes c4b7f42e43 Only compress one version of the builtin-quirks
Saving the quirks in the GResource section worked well, but it made the build
system very complicated and also meant the .data section was duplicated in
both `fwupd` and `fwupdtool` -- negating a lot of the hard-fought savings.

Simplify this feature so that we just `cat` all the quirk files together, then
gzip them into a single file. This means that at startup fwupd only needs to
check the mtime of one file, and weirdly it's actually faster to load a smaller
compressed file from disk that it is to load multiple uncompressed files.

Elan Fingerprint Sensor Support

Introduction

The plugin used for update firmware for fingerprint sensors from Elan.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in a packed binary file format.

This plugin supports the following protocol ID:

  • tw.com.emc.elanfp

GUID Generation

These devices use the standard USB DeviceInstanceId values, e.g.

  • USB\VID_04F3&PID_0C7E&REV_0304
  • USB\VID_04F3&PID_0C7E
  • USB\VID_04F3

Vendor ID Security

The vendor ID is set from the USB vendor, in this instance set to USB:0x04F3
