Now we create object files in a hierarchy under hw/, so the
'clean' target must also be updated to delete those object files.
Rather than using a manual list of subdirectories which will
easily drift out of date, we just delete all .o and .d files
in the target directory hierarchy.

Makes "make check" hang:

TEST: tests/crash-test... (pid=972)
qemu-system-x86_64: Device needs media, but drive is empty
[Nothing happens, wait a while, then hit ^C]
make: *** [check-qtest-x86_64] Interrupt
This was due to the fact that we weren't checked for errors when
reading from the QMP socket. This patch adds appropriate error
checking.

qemu-system-x86_64: Initialization of device ide-hd failed

This error always existed as qdev_init() frees the object. But QOM
goes a bit further and purposefully sets the class pointer to NULL to
help find use-after-free. It worked :-)

If tci_out_label is called in the context of tcg_gen_code_search_pc, we
could be overwriting an already patched relocation with zero -- and not
repatch it because the set_label is past search_pc, causing a QEMU crash
when it tries to branch to a zero label.
Not writing anything to the relocation area seems to be in line with what
other backends do from the couple I looked at (x86, ppc).

Device trees usually have a node /compatible, which indicate which machine
type we're looking at. For quick prototyping, it can be very useful to change
the contents of that node via the command line.
Thus, introduce a new option to -machine called dt_compatible, which when
set changes the /compatible contents to its value.

If anyone outside of QEMU wants to mess with a QEMU generated device tree,
he needs to know which range phandles are valid in. So let's expose a

We want to be able to support >= 4GB of RAM. To do so, we need to be able
to tell the guest OS how much RAM it has.
However, that information today is capped to 32bit. So let's extend the
offset and size fields to 64bit, so we can fit in big addresses and even
one day - if we wish to do so - map devices above 32bit.
