[PATCH v2 0/3] vfio/igd: VFIOConfigMirrorQuirk for igd mirrored registers

[Tomita Moeko]

In commit 1a2623b5c9e7 ("vfio/igd: add macro for declaring mirrored
registers"), I introduced a macro to handle mirrored registers in igd
bar0. However, using the existing VFIOConfigMirrorQuirk should be a
better approach I think after going through the vfio code.

This patch set introduces a new header file, pci-quirks.h, to hold
generic quirk declarations, and extends VFIOConfigMirrorQuirk to
support offsets in PCI config space. This eliminates the need for
the previously introduced macro.

Changelog:
v2:
* Removed 'const Property' change, it was a mistake in rebasing.
* Removed unnecessary initializing config_offset explicitly.
* Separated GGC and BDSM mirror into 2 quirks.
