Previously request_{bios, pflash} cases were skipped on win32, mainly
due to create_blob_file() calling mmap() which does not exist on win32.
This rewirtes create_blob_file() to be portable, so that we can enable
these cases on Windows.

The test is slightly weaker than before, because it does not
call an extern "C" function from a C source file. However,
in practice what we seek to detect is ABI compatibility of the
various sanitizer flags, and for that it is enough to compile
anything with CC and link it with CXX.
This removes the dependency of dbus-display on --enable-modules. It also allows
cleanups in modinfo collection and allows moving C++ compiler detection to
meson.build.
Because it is now deprecated to use install_subdir to create an empty directory,
replace it with install_emptydir.

We currently have hacks across the hw/ to reference current_cpu to
work out what the current accessing CPU is. This breaks in some cases
including using gdbstub to access HW state. As we have MemTxAttrs to
describe details about the access lets extend it so CPU accesses can
be explicitly marked.
As HW virtualization requires specific support to handle breakpoints
lets push out special casing out of the core gdbstub code and into
AccelOpsClass. This will make it easier to add other accelerator
support and reduces some of the stub shenanigans.

One of the reasons for developing libblkio is that other applications

Emulated devices and other BlockBackend users wishing to take advantage
of blk_register_buf() all have the same repetitive job: register
RAMBlocks with the BlockBackend using RAMBlockNotifier.
Add a BlockRAMRegistrar API to do this. A later commit will use this

Use the enum type so GDB displays the enum members instead of printing a

emulation code typically uses the MemoryRegion APIs but vhost-style code
may use RAMBlock directly for sharing guest memory with another process.
This new API will be used by the libblkio block driver so it can share
guest memory
The only implementor of bdrv_register_buf() is block/nvme.c, where the
size is not needed when unregistering a buffer. This is because
util/vfio-helpers.c can look up mappings by address.
Future block drivers that implement bdrv_register_buf() may not be able
to do their job given only the buffer
Avoid bounce buffers when QEMUIOVector elements are within previously
registered bdrv_register_buf() buffers.
The idea is that emulated storage controllers will register guest RAM
using bdrv_register_buf() and set the BDRV_REQ_REGISTERED_BUF on I/O
requests. Therefore no blkio_map_mem_region()

This series is also available as a git branch:
https://github.com/PPC64/qemu/tree/ferst-interrupt-fix-v2
This version addresses Fabiano's feedback and fixes some issues found
with the tests suggested by Cédric. While
Use ppc_set_irq to raise/clear interrupts to ensure CPU_INTERRUPT_HARD
will be set/reset accordingly.

v2:
- Renamed the method from ppc_pending_interrupt_p9 to
p9_next_unmasked_interrupt
Move the interrupt masking logic out of cpu_has_work_POWER9 in a new
method, p9_interrupt_powersave, that only returns an interrupt if it can
wake the processor from power-saving mode. No functional change
intended.

Temporarily putting the prototype in internal.h for lack of a better place,
we will un-export p9_interrupt_powersave in future patches.
