This adds GRAPH_RDLOCK annotations to declare that callers of

Unfortunately we cannot use a co_wrapper_bdrv_rdlock (i.e. make the
coroutine wrapper a no_coroutine_fn), because the function is called
(using the BLKDBG_EVENT macro) by mixed functions that run both in
coroutine and non-coroutine context (for example many of the functions
in qcow2-cluster.c and qcow2-refcount.c).

Drivers were a bit confused about whether .bdrv_open can run in a
coroutine and whether or not it holds a graph lock.
It cannot keep a graph lock from the caller across the whole function
because it both changes the graph (requires a writer lock) and does I/O
(requires a reader lock). Therefore, it should take these locks
internally as needed.
The functions used to be called in coroutine context during image
creation. This was buggy for other reasons, and as of commit 32192301,
all block drivers go through no_co_wrappers. So it is not called in
coroutine context any more.
Fix qcow2 and qed to work with the correct assumptions: The graph lock
needs to be taken internally instead of just assuming it's already
there, and the coroutine path is dead code that can be removed.

For some functions, it is part of their interface to be called without
holding the graph lock. Add a new macro to document this.
The macro expands to TSA_EXCLUDES(), which is a relatively weak check
because it passes in cases where the compiler just doesn't know if the
lock is held. Function pointers can't be checked at all. Therefore, its
primary purpose is documentation.

There is no need for the AioContext lock in aio_wait_bh_oneshot().
It's easy to remove the lock from existing callers and then switch from
AIO_WAIT_WHILE() to AIO_WAIT_WHILE_UNLOCKED() in aio_wait_bh_oneshot().
Document that the AioContext lock should not be held across
aio_wait_bh_oneshot(). Holding a lock across aio_poll() can cause
deadlock so we don't want callers to do that.
This is a step towards getting rid of the AioContext lock.

The arm boot.c code includes a utility function write_bootloader()
which assists in writing a boot-code fragment into guest memory,
including handling endianness and fixing it up with entry point
addresses and similar things. This is useful not just for the boot.c
code but also in board model code, so rename it to
arm_write_bootloader() and make it globally visible.
Since we are making it public, make its API a little neater: move the
AddressSpace* argument to be next to the hwaddr argument, and allow
the fixupcontext array to be const, since we never modify it in this
function.

The 'singlestep' HMP command is confusing, because it doesn't
actually have anything to do with single-stepping the CPU. What it
does do is force TCG emulation to put one guest instruction in each
TB, which can be useful in some situations.
Create a new HMP command 'one-insn-per-tb', so we can document that
'singlestep' is just a deprecated synonym for it, and eventually
perhaps drop it.
We aren't obliged to do deprecate-and-drop for HMP commands,
but it's easy enough to do so, so we do.

The only place left that looks at the old 'singlestep' global
variable is the TCG curr_cflags() function. Replace the old global
with a new 'one_insn_per_tb' which is defined in tcg-all.c and
declared in accel/tcg/internal.h. This keeps it restricted to the
TCG code, unlike 'singlestep' which was available to every file in
the system and defined in multiple different places for softmmu vs
linux-user vs bsd-user.
While we're making this change, use qatomic_read() and qatomic_set()
on the accesses to the new global, because TCG will read it without
holding a lock.

This query copies the kernel command line into the message buffer. It
was previously stubbed out to return empty, this commit makes it reflect
the arguments specified with `-append`.
I observed the following peculiarities on my Pi 3B+:
- If the buffer is shorter than the string, the response header gives
the full length, but no data is actually copied.
- No NUL terminator is added: even if the buffer is long enough to fit
one, the buffer's original contents are preserved past the string's
end.
- The VC firmware adds the following extra parameters beside the
user-supplied ones (via /boot/cmdline.txt): `video`, `vc_mem.mem_base`
and `vc_mem.mem_size`. This is currently not implemented in qemu.

thread_pool_submit_aio() is always called on a pool taken from
qemu_get_current_aio_context(), and that is the only intended
use: each pool runs only in the same thread that is submitting
work to it, it can't run anywhere else.
Therefore simplify the thread_pool_submit* API and remove the
ThreadPool function parameter.

Use qemu_get_current_aio_context() where possible, since we always
submit work to the current thread anyways.
We want to also be sure that the thread submitting the work is
the same as the one processing the pool, to avoid adding
synchronization to the pool list.

In order to prevent mistakes from the caller side, avoid passing LuringState

Previously, PXB_CXL_DEVICE, PXB_PCIE_DEVICE and PXB_DEVICE all
have PCI_DEVICE as their direct parent but share a common state
struct PXBDev. convert_to_pxb() is used to get the PXBDev
instance from which ever of these types it is called on.
This patch switches to an explicit hierarchy based on shared
functionality. To allow use of OBJECT_DECLARE_SIMPLE_TYPE()
whilst minimizing code changes, all types are renamed to have
the postfix _DEV rather than _DEVICE. The new heirarchy
has PXB_CXL_DEV with parent PXB_PCIE_DEV which in turn
has parent PXB_DEV which continues to have parent PCI_DEVICE.
This allows simple use of PXB_DEV() etc rather than a custom function
+ removal of duplicated properties and moving the CXL specific
elements out of struct PXBDev.

i440fx machine versions 2.3 and newer supports dynamic ram
resizing. See commit a1666142db ("acpi-build: make ROMs RAM blocks resizeable") .
Currently supported all q35 machine types (versions 2.4 and newer) supports
resizable RAM/ROM blocks.Therefore the warning generated when the ACPI table
size exceeds a pre-defined value does not apply to those machine versions.
Add a check limiting the warning message to only those machines that does not
support expandable ram blocks (that is, i440fx machines with version 2.2
and older).
