At present, the libqos/fw_cfg.c library does not support the modern DMA

interface. Implement read and write methods based on DMA. This will enable
developers to write tests that writes to the fw_cfg file(s). The structure of
the code is taken from edk2 fw_cfg implementation. It has been tested by
writing a qtest that writes to a fw_cfg file. This test will be part of a
future patch series.
What's the blocker for the rest of the series? It would be preferable to
merge it all together, rather than this going in first without any
users.
Agreed. We could use a multiboot image, or a guest with vmcoreinfo
support. Or a dumbier test just testing this API.
