chardev/char-win-stdio: Pass Ctrl+C to guest with a multiplexed monitor

At present when pressing Ctrl+C from a guest running on QEMU Windows
with a multiplexed monitor, e.g.: -serial mon:stdio, QEMU executable
just exits. This behavior is inconsistent with the Linux version.
Such behavior is caused by unconditionally setting the input mode
ENABLE_PROCESSED_INPUT for a console's input buffer. Fix this by
testing whether the chardev is allowed to do so.

target is failing due to following build warnings:

Most of the changes are trivial. The bits test timeout has now been increased
to 200 seconds in order to accommodate slower systems and fewer unnecessary
failures. Removed of the reference to non-existent README file in docs. Some
minor corrections in the doc file.

The Cirrus CI service has announced the intent to discontinue
support for x86_64 macOS CI runners. They already have aarch64
runners available and require all projects to switch to these
images before Jan 1st 2023. The different architecture is
merely determined by the image name requested.
For aarch64 they only support macOS 12 onwards. At the same
time our support policy only guarantees the most recent 2
major versions, so macOS 12 is already technically our min
version.

The "loadparm" machine property is useful for selecting alternative
kernels on the disk of the guest, but so far we do not tell the users
yet how to use it. Add some documentation to fill this gap.

Note: Though "migrateable" still seems to be a valid spelling, we change
it to "migratable" since this is the way more common spelling here.

When translating code that is using LAHF and SAHF in combination with the
REX prefix, the instructions should not use any other register than AH;
however, QEMU selects SPL (SP being register 4, just like AH) if the
REX prefix is present. To fix this, use deposit directly without
going through gen_op_mov_v_reg and gen_op_mov_reg_v.

Unlike the memory case, where "the destination operand receives a write
cycle without regard to the result of the comparison", rm must not be
touched altogether if the write fails, including not zero-extending
it on 64-bit processors. This is not how the movcond currently works,
because it is always followed by a gen_op_mov_reg_v to rm.
To fix it, introduce a new function that is similar to gen_op_mov_reg_v
but writes to a TCG temporary.
Considering that gen_extu(ot, oldv) is not needed in the memory case
either, the two cases for register and memory destinations are different
enough that one might as well fuse the two "if (mod == 3)" into one.
So do that too.

bdrv_parent_drained_{begin,end}_single() are supposed to operate on the
parent, not on the child, so they should not attempt to get the context
to poll from the child but the parent instead. BDRV_POLL_WHILE(c->bs)
does get the context from the child, so we should replace it with
AIO_WAIT_WHILE() on the parent's context instead.
This problem becomes apparent when bdrv_replace_child_noperm() invokes
bdrv_parent_drained_end_single() after removing a child from a subgraph
that is in an I/O thread. By the time bdrv_parent_drained_end_single()
is called, child->bs is NULL, and so BDRV_POLL_WHILE(c->bs, ...) will
poll the main loop instead of the I/O thread; but anything that
bdrv_parent_drained_end_single_no_poll() may have scheduled is going to
want to run in the I/O thread, but because we poll the main loop, the
I/O thread is never unpaused, and nothing is run, resulting in a
deadlock.

blk_get_aio_context() asserts that blk->ctx is always equal to the root
BDS's context (if there is a root BDS). Therefore,
blk_do_set_aio_context() must update blk->ctx immediately after the root
BDS's context has changed.
Without this patch, the next patch would break iotest 238, because
bdrv_drained_begin() (called by blk_do_set_aio_context()) may then
invoke bdrv_child_get_parent_aio_context() on the root child, i.e.
blk_get_aio_context(). However, by this point, blk->ctx would not have
been updated and thus differ from the root node's context. This patch

We want to use bdrv_child_get_parent_aio_context() from
bdrv_parent_drained_{begin,end}_single(), both of which are "I/O or GS"
functions.
Prior to 3ed4f708fe1, all the implementations were I/O code anyway.
3ed4f708fe1 has put block jobs' AioContext field under the job mutex, so
to make child_job_get_parent_aio_context() work in an I/O context, we
need to take that lock there.
Furthermore, blk_root_get_parent_aio_context() is not marked as
anything, but is safe to run in an I/O context, so mark it that way now.
(blk_get_aio_context() is an I/O code function.)
With that done, all implementations explicitly are I/O code, so we can
mark bdrv_child_get_parent_aio_context() as I/O code, too, so callers
know it is safe to run from both GS and I/O contexts.

Setting it to true can cause the device size to be queried from libblkio
in otherwise fast paths, degrading performance. Set it to false and
require users to refresh the device size explicitly instead.

Before this series, a mirror job in write-blocking mode would pause
issuing background requests while active requests are in flight. Thus,
if the source is constantly in use by active requests, no actual
progress can be made.
This series should have fixed that, making the mirror job issue
background requests even while active requests are in flight.
Have a new test case in 151 verify this.

There is a small gap in mirror_start_job() before putting the mirror
filter node into the block graph (bdrv_append() call) and the actual job
being created. Before the job is created, MirrorBDSOpaque.job is NULL.
It is possible that requests come in when bdrv_drained_end() is called,
and those requests would see MirrorBDSOpaque.job == NULL. Have our
filter node handle that case gracefully.

Waiting for all active writes to settle before daring to create a
background copying operation means that we will never do background
operations while the guest does anything (in write-blocking mode), and
therefore cannot converge. Yes, we also will not diverge, but actually
converging would be even nicer.
It is unclear why we did decide to wait for all active writes to settle
before creating a background operation, but it just does not seem
necessary. Active writes will put themselves into the in_flight bitmap
and thus properly block actually conflicting background requests.
It is important for active requests to wait on overlapping background
requests, which we do in active_write_prepare(). However, so far it was
not documented why it is important. Add such documentation now, and
also to the other call of mirror_wait_on_conflicts(), so that it becomes
more clear why and when requests need to actively wait for other
requests to settle.
Another thing to note is that of course we need to ensure that there are
no active requests when the job completes, but that is done by virtue of
the BDS being drained anyway, so there cannot be any active requests at
that point.
With this change, we will need to explicitly keep track of how many
bytes are in flight in active requests so that
job_progress_set_remaining() in mirror_run() can set the correct number
of remaining bytes.

With commit 39f29e599355 ("hw/intc/arm_gicv3: Use correct number of
priority bits for the CPU") the number of priority bits was changed from
the maximum value 8 to typically 5. As a consequence a few of the lowest
bits in ICC_PMR_EL1 becomes RAZ/WI. However prior to this patch one of
these bits was still used since the supplied priority value is masked
before it's eventually right shifted with one bit. So the bit is not
lost as one might expect when the register is read again.
The Linux kernel depends on lowest valid bit to be reset to zero, see
commit 33625282adaa ("irqchip/gic-v3: Probe for SCR_EL3 being clear
before resetting AP0Rn") for details.
So fix this by masking the priority value after it may have been right
shifted by one bit.

GCC 8 added a -Wstringop-truncation warning:
The -Wstringop-truncation warning added in GCC 8.0 via r254630 for
bug 81117 is specifically intended to highlight likely unintended
uses of the strncpy function that truncate the terminating NUL
character from the source string.
Here the next line indeed unconditionally zeroes the last byte, but
1/ the buffer has been calloc'd, so we don't need to add an extra
byte, and 2/ we called vduse_name_is_invalid() which checked the
string length, so we can simply call strcpy().
This fixes when using gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0:

hw/pci-host/pnv_phb: Avoid quitting QEMU if hotplug of pnv-phb-root-port fails

Currently QEMU terminates if you try to hotplug pnv-phb-root-port in
an environment where it is not supported, e.g. if doing this:
echo "device_add pnv-phb-root-port" | \
./qemu-system-ppc64 -monitor stdio -M powernv9
To avoid this problem, the pnv_phb_root_port_realize() function should
not use error_fatal when trying to set the properties which might not
be available.

That is reported by Alexander Bulekov. https://gitlab.com/qemu-project/qemu/-/issues/1309
Here, the queue_index is the index of the cvq, but in some cases cvq
does not have the corresponding NetClientState, so overflow appears.
I add a check here, ignore illegal queue_index and cvq queue_index.
Note the queue_index is below the VIRTIO_QUEUE_MAX but greater or equal
than cvq index could hit this. Other devices are similar.

acpi-vga-stub.c pulls in vga_int.h
However that currently pulls in ui/console.h which
breaks e.g. on systems without pixman.
It's better to remove ui/console.h from vga_int.h
and directly include it where it's used.
