Mark functions as coroutine_fn when they are only called by other coroutine_fns
and they can suspend. Because this function operates on a BlockBackend, mark it
GRAPH_UNLOCKED.

Mark functions as coroutine_fn when they are only called by other coroutine_fns
and they can suspend. Change calls to co_wrappers to use the non-wrapped

raw_co_getlength is called by handle_aiocb_write_zeroes, which is not a coroutine
function. This is harmless because raw_co_getlength does not actually suspend,
but in the interest of clarity make it a non-coroutine_fn that is just wrapped
by the coroutine_fn raw_co_getlength. Likewise, check_cache_dropped was only
a coroutine_fn because it called raw_co_getlength, so it can be made non-coroutine
as well.

Now that bdrv_graph_wrlock() temporarily drops the AioContext lock that
its caller holds, it can poll without causing deadlocks. We can now
re-enable graph locking.

If the caller keeps the AioContext lock for a block node in an iothread,
polling in bdrv_graph_wrlock() deadlocks if the condition isn't
fulfilled immediately.
Now that all callers make sure to actually have the AioContext locked
when they call bdrv_replace_child_noperm() like they should, we can
change bdrv_graph_wrlock() to take a BlockDriverState whose AioContext
lock the caller holds (NULL if it doesn't) and unlock it temporarily
while polling.

This is a better regression test for the bugs hidden by commit 80fc5d26
('graph-lock: Disable locking for now'). With that commit reverted, it
hangs instantaneously and reliably for me.
It is important to have a reliable test like this, because the following
commits will set out to fix the actual root cause of the deadlocks and
then finally revert commit 80fc5d26, which was only a stopgap solution.

SUN Type 4, 5 and 5c keyboards have dip switches to choose the language layout
of the keyboard. Solaris makes an ioctl to query the value of the dipswitches
and uses that value to select keyboard layout. Also the SUN bios like the one
in the file ss5.bin uses this value to support at least some keyboard layouts.
However, the OpenBIOS provided with qemu is hardcoded to always use an US
keyboard layout.
Before this patch, qemu allways gave dip switch value 0x21 (US keyboard),
this patch uses a command line switch like
"-global escc.chnA-sunkbd-layout=de" to select dip switch value. A table is
used to lookup values from arguments like:
-global escc.chnA-sunkbd-layout=fr
-global escc.chnA-sunkbd-layout=es
But the patch also accepts numeric dip switch values directly:
-global escc.chnA-sunkbd-layout=0x2b
-global escc.chnA-sunkbd-layout=43
Both values above are the same and select swedish keyboard as explained in
table 3-15 at
https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html
Unless you want to do a full Solaris installation but happen to have
access to a Sun bios file, the easiest way to test that the patch works
is to:
qemu-system-sparc -global escc.chnA-sunkbd-layout=sv -bios /path/to/ss5.bin
If you already happen to have a Solaris installation in a qemu disk image
file you can easily try different keyboard layouts after this patch is
applied.

We incorporate %asi into tb->flags so that we may generate
inline code for the many ASIs for which it is easy to do so.
Setting %asi is common for e.g. memcpy and memset performing
block copy and clear, so it is worth noticing this case.
We must end the TB but do not need to return to the main loop.

net/vhost-net: do not assert on null pointer return from tap_get_vhost_net()

When 'vhost=off' or no vhost specific options at all are passed for the tap
net-device backend, tap_get_vhost_net() can return NULL. The function
net_init_tap_one() does not call vhost_net_init() on such cases and therefore
vhost_net pointer within the tap device state structure remains NULL. Hence,
assertion here on a NULL pointer return from tap_get_vhost_net() would not be
correct. Remove it and fix the crash generated by qemu upon initialization in
the following call chain :
qdev_realize() -> pci_qdev_realize() -> virtio_device_realize() ->
virtio_bus_device_plugged() -> virtio_net_get_features() -> get_vhost_net()

If we don't have NVME_CMD_COPY consideration in the switch statement in
nvme_aio_err(), it will go to have NVME_INTERNAL_DEV_ERROR and
`req->status` will be ovewritten to it. During the aio context, it
might set the NVMe status field like NVME_CMD_SIZE_LIMIT, but it's
overwritten in the nvme_aio_err().
Add consideration for the NVME_CMD_COPY not to overwrite the status at
the end of the function.

When the display surface has an associated HANDLE, we can duplicate it
to the client process and let it map the memory to avoid expensive copies.
Introduce two new win32-specific methods ScanoutMap and UpdateMap. The
first is used to inform the listener about the a shared map
availability, and the second for display updates.
