In the GTK UI, after changing focus to the qemu monitor Notebook Page,
when restoring focus to the virtual machine page, the keyboard focus is lost
to a hidden GTK widget. Focus can only be restored to the virtual machine by
pressing "tab" or any of the four directional arrow keys.

Clicking in the window or grabbing/ungrabbing input does not restore keyboard
focus to the child widget.

This patch adjusts the Notebook page switching callback to automatically
steal keyboard focus on the Page switch event, so that keyboard input
does not appear to break or disappear after tabbing to the QEMU monitor.

The buffer was being allocated of size string length plus two.
Around the string two quotes were being added, but no terminating NUL.
It was then compared using g_assert_cmpstr(), resulting in fairly random
assertion failures:

 ERROR:tests/test-string-output-visitor.c:213:test_visitor_out_enum: assertion failed (str == str_human): ("\"value1\"" == "\"value1\"\001EEEEEEEEEEEEEE\0171")

There is no g_assert_cmpnstr() counterpart, so use g_strdup_printf()
for safely assembling the string in the first place.

POWER8E is architecturally equal to POWER8 and POWER7+ is equal to
POWER7. Also no user space tool makes any difference for CPU node name
in the device tree (such as PowerPC,POWER7@0 vs. PowerPC,POWER7+@0).
So there is no point in emulating POWER7+ and POWER8E apart from POWER7
and POWER8. Also, the previos patch implemented multiple PVR mask support
per CPU class so POWER7 class now covers both POWER7 and POWER7+ CPUs,
same is valid for POWER8/8E.

This removes POWER7+ and POWER8E classes. This replaces references
to POWER7P/POWER8E families with POWER7/POWER8 families.

So far it was enough to have a base PVR value and mask per CPU
family such as POWER7 or POWER8. However there CPUs which are
completely architecturally compatible but have different PVRs such
as POWER7/POWER7+ and POWER8/POWER8E. For these CPUs, top 16 bits
are CPU family and low 16 bits are the version. The families have
PVR base values different enough so defining a mask which
would cover both (or potentially more) CPUs within the family is
not possible.

This adds a pvr_match() callback to PowerPCCPUClass. The default
handler simply compares PVR defined in the class.

This implements ppc_pvr_match_power7/ppc_pvr_match_power8 callbacks
for POWER7/8 families. These check for POWER7/POWER7+ and POWER8/POWER8E.

This changes ppc_cpu_compare_class_pvr_mask() not to check masks but
use the pvr_match() callback.

Since all server CPUs use the same mask, this defines one mask
value - CPU_POWERPC_POWER_SERVER_MASK - which is used everywhere now.
This removes other mask definitions.

This removes pvr_mask from PowerPCCPUClass as it is not used anymore.
This removes pvr initialization for POWER7/8 families as it is not used
to find the class, the pvr_match() callback is used instead.

Devices can use a mix of qdev and QOM properties.  Currently only the
qdev properties are displayed by device-list-properties.

This patch extends the property enumeration algorithm to also display
QOM properties (excluding the implicit "type", "realized",
"hotpluggable", and "parent_bus" properties).

When a qdev property exists, use the qdev type name to preserve
backwards compatibility.  QOM type names can be different for bool (qdev
on/off) and str (used by qdev pointers).

Before commit 580b6b2a(dataplane: use the QEMU block
layer for I/O), dataplane for virtio-blk submits block
I/O as a batch.

This commit 580b6b2a replaces the custom linux AIO
implementation(including submit I/O as a batch) with QEMU
block layer, but this commit causes ~40% throughput regression
on virtio-blk performance, and removing submitting I/O
as a batch is one of the causes.

This patch applies the newly introduced bdrv_io_plug() and
bdrv_io_unplug() interfaces to support submitting I/O
at batch for Qemu block layer, and in my test, the change
can improve throughput by ~30% with 'aio=native'.

Following my fio test script:
