qcow2: Fix corruption bug in qcow2_detect_metadata_preallocation()

qcow2_detect_metadata_preallocation() calls qcow2_get_refcount() which
requires s->lock to be taken to protect its accesses to the refcount
table and refcount blocks. However, nothing in this code path actually
took the lock. This could cause the same cache entry to be used by two
requests at the same time, for different tables at different offsets,
resulting in image corruption.

As it would be preferable to base the detection on consistent data (even
though it's just heuristics), let's take the lock not only around the
qcow2_get_refcount() calls, but around the whole function.

This patch takes the lock in qcow2_co_block_status() earlier and asserts
in qcow2_detect_metadata_preallocation() that we hold the lock.

hw/dma/xilinx_axidma.c: Switch to transaction-based ptimer API

Switch the xilinx_axidma code away from bottom-half based ptimers to
the new transaction-based ptimer API.  This just requires adding
begin/commit calls around the various places that modify the ptimer
state, and using the new ptimer_init() function to create the timer.

target/arm: Rely on hflags correct in cpu_get_tb_cpu_state

This is the payoff.

From perf record -g data of ubuntu 18 boot and shutdown:

BEFORE:

-   23.02%     2.82%  qemu-system-aar  [.] helper_lookup_tb_ptr
   - 20.22% helper_lookup_tb_ptr
      + 10.05% tb_htable_lookup
      - 9.13% cpu_get_tb_cpu_state
           3.20% aa64_va_parameters_both
           0.55% fp_exception_el

-   11.66%     4.74%  qemu-system-aar  [.] cpu_get_tb_cpu_state
   - 6.96% cpu_get_tb_cpu_state
        3.63% aa64_va_parameters_both
        0.60% fp_exception_el
        0.53% sve_exception_el

AFTER:

-   16.40%     3.40%  qemu-system-aar  [.] helper_lookup_tb_ptr

     0.87%     0.24%  qemu-system-aar  [.] rebuild_hflags_a64

Before, helper_lookup_tb_ptr is the second hottest function in the
application, consuming almost a quarter of the runtime.  Within the
entire execution, cpu_get_tb_cpu_state consumes about 12%.

After, helper_lookup_tb_ptr has dropped to the fourth hottest function,
with consumption dropping to a sixth of the runtime.  Within the
entire execution, cpu_get_tb_cpu_state has dropped below 1%, and the
supporting function to rebuild hflags also consumes about 1%.

Assertions are retained for --enable-debug-tcg.

spapr/xive: Set the OS CAM line at reset

hypervisor pushes its identifier in the OS CAM line. When running with
kernel_irqchip=off, QEMU needs to emulate the same behavior.

Set the OS CAM line when the interrupt presenter of the sPAPR core is
reset. This will also cover the case of hot-plugged CPUs.

This change also has the benefit to remove the use of CPU_FOREACH()
which can be unsafe.

ppc: Reset the interrupt presenter from the CPU reset handler

On the sPAPR machine and PowerNV machine, the interrupt presenters are
created by a machine handler at the core level and are reset
independently. This is not consistent and it raises issues when it
comes to handle hot-plugged CPUs. In that case, the presenters are not
reset. This is less of an issue in XICS, although a zero MFFR could
be a concern, but in XIVE, the OS CAM line is not set and this breaks
the presenting algorithm. The current code has workarounds which need
a global cleanup.

Extend the sPAPR IRQ backend and the PowerNV Chip class with a new
cpu_intc_reset() handler called by the CPU reset handler and remove
the XiveTCTX reset handler which is now redundant.

spapr_cpu_core: Implement DeviceClass::reset

Since vCPUs aren't plugged into a bus, we manually register a reset
handler for each vCPU. We also call this handler at realize time
to ensure hot plugged vCPUs are reset before being exposed to the
guest. This results in vCPUs being reset twice at machine reset.
It doesn't break anything but it is slightly suboptimal and above
all confusing.

The hotplug path in device_set_realized() already knows how to reset
a hotplugged device if the device reset handler is present. Implement
one for sPAPR CPU cores that resets all vCPUs under a core.

While here rename spapr_cpu_reset() to spapr_reset_vcpu() for
consistency with spapr_realize_vcpu() and spapr_unrealize_vcpu().
