This is similar to the existing 'add pointer' functionality, but instead
of instructing the guest (BIOS or UEFI) to patch memory, it instructs
the guest to write the pointer back to QEMU via a writeable fw_cfg file.

This adds support for three additional options that may be specified
by QAPI in blockdev-add:
server: host, port
auth method: either 'cephx' or 'none'
The "server" and "auth-supported" QAPI parameters are arrays. To conform
with the rados API, the array items are join as a single string with a ';'
character as a delimiter when setting the configuration values.

When compiling with SDL2, the semaphore trick used in sdlaudio.c
does not work - QEMU locks up completely in this case. To avoid
the hang and get at least some audio playback up and running (it's
a little bit crackling, but better than nothing), we can use the
SDL locking functions SDL_LockAudio() and SDL_UnlockAudio() to sync
with the sound playback thread instead.

This patch changes resetting strategy of the audio polling timer.
It does not change expiration time if the timer is already set.
This patch is needed to make this timer deterministic and to use execution
record/replay for audio devices.
audio_reset_timer is used in the function audio_vm_change_state_handler.
Therefore every time VM is stopped or restarted the timer will be reset
to new timeout. Virtual clock does not proceed while VM is stopped.
Therefore there is no need in resetting the timeout when VM restarts.

Apparently, none of the bus owner give a reference to the hotplug
handler property, do not unref it on bus release.
Furthermore, a bus is allowed to be its own hotplug handler, which can
be seen in qbus_set_bus_hotplug_handler() function. However, in this
case, the reference can't be given to the property, or this will create
a cyclic dependency and the bus will never be free.
Each bus owner should manage the lifecycle of the hotplug handler.

PCI hotplug for bridges was introduced only since 2.0 however
acpi_set_bsel()->object_property_add_uint32_ptr(bus, ACPI_PCIHP_PROP_BSEL)
didn't take in account that for legacy mode (1.7) when
PCI hotplug for bridges is unavailable and ACPI_PCIHP_PROP_BSEL property
the only bus "PCI.0' has been created earlier at acpi_pcihp_init() time.
We managed to live with it only because of error rised by adding
a duplicate property in acpi_set_bsel() has been ignored which
resulted in useless leaking of just allocated (int)bus_bsel.
Issue affects only 1.7 machine type as ACPI tables supported by
QEMU were introduced at that time, but there wasn't PCI hotplug
for bridges till the next release (2.0).
Fix it by removing duplicate ACPI_PCIHP_PROP_BSEL intialization
in acpi_pcihp_init() and doing it only in one place acpi_set_pci_info().
PS:
do not ignore error returned by object_property_add_uint32_ptr()
and abort QEMU since it's programming error which should be fixed
instead of being ignored.

This patch extends support for the `dump-guest-memory` command to the

guest will not dump a 32-bit core file (and vice versa).
[dwg: I suspect this patch won't cover all cases, in particular a
32-bit machine type on a 64-bit qemu build. However, it does strictly
more than what we had before, so might as well apply as a starting
