Whenever a symbol is referenced from multiple subdirectories, the
script prints the list of directories that reference the symbol.
These symbols have to be added manually to the Kconfig files.
Kconfig.host and hw/Kconfig were created manually.

This patch adds an optional function pointer, 'elf_note_fn', to
load_elf() which causes load_elf() to additionally parse any
ELF program headers of type PT_NOTE and check to see if the ELF
Note is of the type specified by the 'translate_opaque' arg.
If a matching ELF Note is found then the specfied function pointer
is called to process the ELF note.
Passing a NULL function pointer results in ELF Notes being skipped.
The first consumer of this functionality is the PVHboot support
which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while
loading the uncompressed kernel binary in order to discover the
boot entry address for the x86/HVM direct boot ABI.

The typhoon MemoryRegionOps callbacks directly call
cpu_unassigned_access(), presumably as the old-fashioned way
to provoke a CPU exception. This won't work since commit
6ad4d7eed0 when we switched Alpha over to the
transaction_failed hook API, because now cpu_unassigned_access()
is a no-op for Alpha.
Make the MemoryRegionOps callbacks use the read_with_attrs
and write_with_attrs hooks, so they can signal a failure
that should cause a CPU exception by returning MEMTX_ERROR.

This defines new QOM object - IOMMUMemoryRegion - with MemoryRegion
as a parent.
This moves IOMMU-related fields from MR to IOMMU MR. However to avoid
dymanic QOM casting in fast path (address_space_translate, etc),
this adds an @is_iommu boolean flag to MR and provides new helper to
do simple cast to IOMMU MR - memory_region_get_iommu. The flag
is set in the instance init callback. This defines
memory_region_is_iommu as memory_region_get_iommu()!=NULL.

Block backends defined with -drive if=ide are meant to be picked up by
machine initialization code: a suitable frontend gets created and
wired up automatically.
if=ide drives not picked up that way can still be used with -device as
if they had if=none, but that's unclean and best avoided. Unused ones
produce an "Orphaned drive without device" warning.
-drive parameter "if" is optional, and the default depends on the
machine type. If a machine type doesn't specify a default, the
default is "ide".
Many machine types default to if=ide, even though they don't actually
have an IDE controller. A future patch will change these defaults to
something more sensible. To prepare for it, this patch makes default
"ide" explicit for the machines that actually pick up if=ide drives:
* alpha: clipper
* arm/aarch64: spitz borzoi terrier tosa
* i386/x86_64: generic-pc-machine (with concrete subtypes pc-q35-*

* ppc/ppc64: mac99 g3beige prep

explicitly. Its IDE controller isn't implemented, yet.

folder of the QEMU sources slowly gets quite overcrowded with the

To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

Some CPUs are of an opposite data-endianness to other components in the
system. Sometimes elfs have the data sections layed out with this CPU
data-endianness accounting for when loaded via the CPU, so byte swaps
(relative to other system components) will occur.
The leading example, is ARM's BE32 mode, which is is basically LE with
address manipulation on half-word and byte accesses to access the
hw/byte reversed address. This means that word data is invariant
across LE and BE32. This also means that instructions are still LE.
The expectation is that the elf will be loaded via the CPU in this
endianness scheme, which means the data in the elf is reversed at
compile time.
As QEMU loads via the system memory directly, rather than the CPU, we
need a mechanism to reverse elf data endianness to implement this
possibility.

We can have at most one ISA bus. If you try to create another one,
isa_bus_new() complains to stderr and returns null.
isa_bus_new() is called in two contexts, machine's init() and device's
realize() methods. Since complaining to stderr is not proper in the
latter context, convert isa_bus_new() to Error.
Machine's init():
* mips_jazz_init(), called from the init() methods of machines
"magnum" and "pica"
* mips_r4k_init(), the init() method of machine "mips"
* pc_init1() called from the init() methods of non-q35 PC machines
* typhoon_init(), called from clipper_init(), the init() method of
machine "clipper"
These callers always create the first ISA bus, hence isa_bus_new()
can't fail. Simply pass &error_abort.
Device's realize():
* i82378_realize(), of PCI device "i82378"
* ich9_lpc_realize(), of PCI device "ICH9-LPC"
* pci_ebus_realize(), of PCI device "ebus"
* piix3_realize(), of PCI device "pci-piix3", abstract parent of
"PIIX3" and "PIIX3-xen"
* piix4_realize(), of PCI device "PIIX4"
* vt82c686b_realize(), of PCI device "VT82C686B"
Propagate the error. Note that these devices are typically created
only by machine init() methods with qdev_init_nofail() or similar. If
we screwed up and created an ISA bus before that call, we now give up
right away. Before, we'd hobble on, and typically die in
isa_bus_irqs(). Similar if someone finds a way to hot-plug one of
these critters.

Printing CPU registers is not helpful during machine initialization.
Moreover, these are straightforward configuration or "can get
resources" errors, so dumping core isn't appropriate either. Replace
hw_error() by error_report(); exit(1). Matches how we report these
errors in other machine initializations.
