When several PCI bridges were in use, monitor command "info pci" would
enter into infinite loop. Buses behind the bridge were not discoverable
because secondary and subordinate bus numbers were not used properly.
Other buses were not found because bus search terminated on first miss.

This reverts commit 2ba6edf0dd.
The commit has two issues:
* When it runs from the monitor, e.g. "device_add e1000,?", it prints
to stderr instead of the monitor.
* Help looks to callers just like failed device creation. This makes
main() exit unsuccessfully on "-device e1000,?".
We need to do this differently.

This reverts commit 922910ce42.
The commit has four issues:
* When it runs from the monitor, e.g. "device_add e1000,mac=?", it
prints to stderr instead of the monitor.
* Help looks to callers just like failed device creation. This makes
main() exit unsuccessfully on "-device e1000,mac=?".
* It has an undocumented side effect on -global: "-global e1000.mac=?"
prints help, but only when we actually add an e1000 device.
* It does not work for properties that accept the value "?".
We need to do this differently.

Help was shoehorned into device creation, qdev_device_add(). Since
help doesn't create a device, it returns NULL, which looks to callers
just like failed device creation. Monitor handler do_device_add()
doesn't care, but main() exits unsuccessfully.
Move help out of device creation, into new qdev_device_help().

sparc64 timer has tick counter which can be set and read,
and tick compare value used as deadline to fire timer interrupt.
The timer is not used as periodic timer, instead deadline
is set each time new timer interrupt is needed.
v3 -> v4:
- coding style
v2 -> v3:
- added missing timer debug output macro
- CPUTimer struct and typedef moved to cpu.h
- change CPU_SAVE_VERSION to 6, older save formats not supported
v1 -> v2:
- new conversion helpers cpu_to_timer_ticks and timer_to_cpu_ticks
- save offset from clock source to implement cpu_tick_set_count
- renamed struct sun4u_timer to CPUTimer
- load and save cpu timers

When using ballooning to manage overcommitted memory on a host, a system for
guests to communicate their memory usage to the host can provide information
that will minimize the impact of ballooning on the guests. The current method
employs a daemon running in each guest that communicates memory statistics to a
host daemon at a specified time interval. The host daemon aggregates this
information and inflates and/or deflates balloons according to the level of
host memory pressure. This approach is effective but overly complex since a
daemon must be installed inside each guest and coordinated to communicate with
the host. A simpler approach is to collect memory statistics in the virtio
balloon driver and communicate them directly to the hypervisor.

Win32 suffers from a very big memory leak when dealing with SCSI devices.
Each read/write request allocates memory with qemu_memalign (ie
VirtualAlloc) but frees it with qemu_free (ie free).
Pair all qemu_memalign() calls with qemu_vfree() to prevent such leaks.

If migration takes place between write of the bmdma address register and
write of the command register (to initiate DMA), the destination will
not properly start the DMA op, hanging the guest:

This commit completes the do_pci_info() conversion to
QObject by adding support to PCI bridge devices.
This is done by recursively adding devices in the
"pci_bridge" key.
IMPORTANT: This code is being added separately because I could
NOT test it properly. According to Michael Tsirkin, it depends
on ultrasparc and it would take time to do the proper setup.

The returned QObject is a QList of all buses. Each bus is
represented by a QDict, which has a key with a QList of all
PCI devices attached to it. Each device is represented by
a QDict.
As has happended to other complex conversions, it's hard to
split this commit as part of it are new functions which are
called by each other.
IMPORTANT: support for printing PCI bridge attached devices
is NOT part of this commit, it's going to be added by the
next commit, as it's untested.
