This change is needed because commit 06e12b65
now uses an unsigned long long value
(uint64_t && unsigned long long => unsigned long long).

This patch adds support for a usb-redir device, which takes a chardev
as a communication channel to an actual usbdevice using the usbredir protocol.
Compiling the usb-redir device requires usbredir-0.3 to be installed for
the usbredir protocol parser, usbredir-0.3 also contains a server for
redirecting usb traffic from an actual usb device. You can get the 0.3
release of usbredir here:
http://people.fedoraproject.org/~jwrdegoede/usbredir-0.3.tar.bz2
(getting a more formal site for it is a WIP)
Example usage:
1) Start usbredirserver for a usb device:
sudo usbredirserver 045e:0772
2) Start qemu with usb2 support + a chardev talking to usbredirserver +
a usb-redir device using this chardev:
qemu ... \
-readconfig docs/ich9-ehci-uhci.cfg \
-chardev socket,id=usbredirchardev,host=localhost,port=4000 \
-device usb-redir,chardev=usbredirchardev,id=usbredirdev

This patch implements MMU faults caused by TTE.NFO and TTE.E:
- access other than nonfaulting load to a page marked NFO should
raise data_access_exception
- nonfaulting load to a page marked with E bit should raise
data_access_exception
To distinguish nonfaulting loads, this patch extends (abuses?) the rw
argument of get_physical_address_data(). rw is set to 4 on nonfaulting
loads.

Nonfaulting loads should raise fast_data_access_MMU_miss traps as
normal loads do. It is up to the guest OS kernel that detect MMU misses
on nonfaulting load instructions and make them complete without signaling.

cpu_get_phys_page_nofault() calls get_physical_address() twice,
that results in overwriting the fault status in the SFSR.
We need this change in order for nonfaulting loads to raising MMU faults
as normal loads do.
Also removed the call to cpu_get_physical_page_desc() since we are
going to modify nonfaulting loads raising MMU faults.

This patch makes cpu_get_phys_page_debug() independent from
cpu_get_phys_page_nofault() in advance of implementing nonfaulting load.
This also modifies cpu_get_phys_page_nofault() to be compiled only on
TARGET_SPARC64 because it is not required on SPARC32.

This adds the initial set of QMP/QAPI commands provided by the guest
agent:
guest-sync
guest-ping
guest-info
guest-shutdown
guest-file-open
guest-file-read
guest-file-write
guest-file-seek
guest-file-flush
guest-file-close
guest-fsfreeze-freeze
guest-fsfreeze-thaw
guest-fsfreeze-status
The input/output specification for these commands are documented in the
schema.
Example usage:
host:
qemu -device virtio-serial \
-chardev socket,path=/tmp/vs0.sock,server,nowait,id=qga0 \
-device virtserialport,chardev=qga0,name=org.qemu.quest_agent.0
...
echo "{'execute':'guest-info'}" | socat stdio unix-connect:/tmp/qga0.sock
guest:
qemu-ga -m virtio-serial -p /dev/virtio-ports/org.qemu.guest_agent.0 \

This is the actual guest daemon, it listens for requests over a
virtio-serial/isa-serial/unix socket channel and routes them through
to dispatch routines, and writes the results back to the channel in
a manner similar to QMP.
A shorthand invocation:
qemu-ga -d
Is equivalent to:
qemu-ga -m virtio-serial -p /dev/virtio-ports/org.qemu.guest_agent.0 \
-f /var/run/qemu-ga.pid -d

This is the code generator for qapi command marshaling/dispatch.
Currently only generators for synchronous qapi/qmp functions are
supported. This script generates the following files:
$(prefix)qmp-marshal.c: command marshal/dispatch functions for each
QMP command defined in the schema. Functions
generated by qapi-visit.py are used to
convert qobjects recieved from the wire into
function parameters, and uses the same
visiter functions to convert native C return
values to qobjects from transmission back
over the wire.
$(prefix)qmp-commands.h: Function prototypes for the QMP commands
specified in the schema.
$(prefix) is used in the same manner as with qapi-types.py

This is the code generator for qapi visiter functions used to

files:
$(prefix)qapi-visit.c: visiter function for a particular c type, used
to automagically convert qobjects into the
corresponding C type and vice-versa, and well
as for deallocation memory for an existing C
type
$(prefix)qapi-visit.h: declarations for previously mentioned visiter
functions
$(prefix) is used as decribed for qapi-types.py

This is the code generator for qapi types. It will generation the
following files:
$(prefix)qapi-types.h - C types corresponding to types defined in
the schema you pass in
$(prefix)qapi-types.c - Cleanup functions for the above C types
The $(prefix) is used to as a namespace to keep the generated code from
one schema/code-generation separated from others so code and be
generated from multiple schemas with clobbering previously created code.

Given an object recieved via QMP, this code uses the dispatch table
provided by qmp_registry.c to call the corresponding marshalling/dispatch
function and format return values/errors for delivery to the QMP.
Currently only synchronous QMP functions are supported, but this will
also be used for async QMP functions and QMP guest proxy dispatch as
well.

Base definitions/includes for Visiter interface used by generated
visiter/marshalling code.
Includes a GenericList type. Our lists require an embedded element.
Since these types are generated, if you want to use them in a different
type of data structure, there's no easy way to add another embedded
element. The solution is to have non-embedded lists and that what this is.

GLib is an extremely common library that has a portable thread implementation
along with tons of other goodies.
GLib and GObject have a fantastic amount of infrastructure we can leverage in
QEMU including an object oriented programming infrastructure.
Short term, it has a very nice thread pool implementation that we could leverage
in something like virtio-9p. It also has a test harness implementation that
this series will use.

Commit e4ea5e2d0e0e4c5188ab45b66f3195062ae059dc added the use of
the macro GCC_FMT_ATTR to error.h, however compiler.h is not
included by error.h
This will cause a build error when files including error.h
don't include qemu-common.h (or compiler.h). Not an issue today
because the only file including it is json-parser.h and it does
include qemu-common.h, but let's get it fixed.

This moves compiler related macros from qemu-common.h to compiler.h.
The reason for this change is that there are simple header files that
depend only on the compiler macros, so including qemu-common.h is overkill.
Besides, qemu-common.h is bloated and will benefit from some splitting.
Please, also note that the QEMU_BUILD_BUG_ON() macro is being fixed to
not use double underscores as a prefix and the license text was added
by Vassili Karpov (malc), who is one of the authors of the new file.

Add QMP bits for snapshot_blkdev command. This is the same as
snapshot_blkdev in the human monitor. The command is synchronous.
In the future async commands and or a break down of the functionality
into multiple commands might be added.
Also change the 'snapshot_file' argument to 'snapshot-file' in
the human monitor, so that it matches QMP.
