i440fx-test: add test to compare default register values

This test compares all of the default register values against the
spec. It turns out we deviate in quite a few places. These
places are really only visible to the BIOS though which is why
this hasn't created any problems....

libqos: add fw_cfg support

fw_cfg is needed to get the top of memory which is necessary for
doing PCI allocation and allocating RAM for DMA.

Add a PC version of fw_cfg and enough abstraction to support other
platforms.

libqos: add malloc support

This is a very simple allocator for the PC platform. It should

qtest: don't use system command to avoid double fork

Currently we waitpid on the child process we spawn off that does
nothing more than system() another process. While this does not
appear to be incorrect, it's wasteful and confusing so get rid of
it.

hw: move headers to include/

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches....

qcow2: Gather clusters in a looping loop

Instead of just checking once in exactly this order if there are
dependendies, non-COW clusters and new allocation, this starts looping
around these. This way we can, for example, gather non-COW clusters after
new allocations as long as the host cluster offsets stay contiguous....
