For historical reasons each mos6522 instance implements its own setting and
update of the IFR flag bits using methods exposed by MOS6522DeviceClass. As
of today this is no longer required, and it is now possible to implement
the mos6522 IRQs as standard qdev gpios.
Switch over to use qdev gpios for the mos6522 device and update all instances
accordingly.

The second bit of IAPC_BOOT_ARCH in FADT table indicates the presence of
keyboard controller implemented as 8042 or equivalent micro controller. This
change enables this flag for microvms if such a device exists (for example,
when added explicitly from the QEMU commandline). Change
654701e292d98b308b0 ("hw/acpi: add indication for i8042 in IA-PC boot flags of the FADT table")
enabled this flag for i386 q35 based machines. The reason for doing the same
for micro-vms is to make sure we provide the correct tables to the guest OS
uniformly in all cases when an i8042 device is present. When this bit is not
enabled, guest OSes has to find other indirect methods to detect the device
which we would like to avoid.

_bind_hack() was a quick fix to allow async QMP to call bind(2) prior to
calling listen(2) and accept(2). This wasn't sufficient to fully address
the race condition present in synchronous clients.
With the race condition in legacy.py fixed (see the previous commit),
there are no longer any users of _bind_hack(). Drop it.

legacy.py provides a synchronous model. iotests frequently uses this
paradigm:
- create QMP client object
- start QEMU process
- await connection from QEMU process
In the switch from sync to async QMP, the QMP client object stopped
calling bind() and listen() during the QMP object creation step, which
creates a race condition if the QEMU process dials in too quickly.
With refactoring out of the way, restore the former behavior of calling
bind() and listen() during __init__() to fix this race condition.

Add start_server() and accept() methods that can be used instead of
start_server_and_accept() to allow more fine-grained control over the
incoming connection process.
(Eagle-eyed reviewers will surely notice that it's a bit weird that
"CONNECTING" is a state that's shared between both the start_server()
and connect() states. That's absolutely true, and it's very true that
checking on the presence of _accepted as an indicator of state is a
hack. That's also very certainly true. But ... this keeps client code an
awful lot simpler, as it doesn't have to care exactly *how* the
connection is being made, just that it *is*. Is it worth disrupting that
simplicity in order to provide a better state guard on `accept()`? Hm.)

Refactor _do_accept() into _do_start_server() and _do_accept(). As of
this commit, the former calls the latter, but in subsequent commits
they'll be split apart.

As part of disentangling the monolithic nature of _do_accept(), split
out the incoming callback to prepare for factoring out the "wait for a

outside of this method.

These two methods attempted to entirely envelop the logic of
establishing a connection to a peer start to finish. However, we need to
break apart the incoming connection step into more granular steps. We
will no longer be able to reasonably constrain the logic inside of these
helper functions.
So, remove them - with _session_guard(), they no longer serve a real
purpose.
Although the public API doesn't change, the internal API does. Now that
there are no intermediary methods between e.g. connect() and
_do_connect(), there's no hook where the runstate is set. As a result,
the test suite changes a little to cope with the new semantics of
_do_accept() and _do_connect().
Lastly, take some pieces of the now-deleted docstrings and move
them up to the public interface level. They were a little more detailed,
and it won't hurt to keep them.

Previously, I had a method named "accept()" that under-the-hood calls
bind(2), listen(2) *and* accept(2). I meant this as a simplification and
counterpart to the one-shot "connect()" method.
This is confusing to readers who expect accept() to mean *just*
accept(2). Since I need to split apart the "accept()" method into
multiple methods anyway (one of which strongly resembling accept(2)), it
feels pertinent to rename this method *now*.
Rename this all-in-one method "start_server_and_accept()" instead.

In _new_session, there's a fairly complex except clause that's used to
give semantic errors to callers of accept() and connect(). We need to
create a new two-step replacement for accept(), so factoring out this
piece of logic will be useful.
Bolster the comments and docstring here to try and demystify what's
going on in this fairly delicate piece of Python magic.
(If we were using Python 3.7+, this would be an @asynccontextmanager. We
don't have that very nice piece of magic, however, so this must take an
Awaitable to manage the Exception contexts properly. We pay the price
for platform compatibility.)

The BootLinux tests are currently failing with an ugly python

check the return value of find_free_port() instead and cancel the

The trace_gicv3_icv_hppir_read trace event takes an integer value
which it uses to form the register name, which should be either
ICV_HPPIR0 or ICV_HPPIR1. We were passing in the 'grp' variable for
this, but that is either GICV3_G0 or GICV3_G1NS, which happen to be 0
and 2, which meant that tracing for the ICV_HPPIR1 register was
incorrectly printed as ICV_HPPIR2.
Use the same approach we do for all the other similar trace events,
and pass in 'ri->crm == 8 ? 0 : 1', deriving the index value
directly from the ARMCPRegInfo struct.

The GICv3 has some registers that support byte accesses, and some
that support 8-byte accesses. Our TCG implementation implements all
of this, switching on the 'size' argument and handling the registers
that must support reads of that size while logging an error for
attempted accesses to registers that do not support that size access.
However we forgot to tell the core memory subsystem about this by
specifying the .impl and .valid fields in the MemoryRegionOps struct,
so the core was happily simulating 8 byte accesses by combining two 4
byte accesses. This doesn't have much guest-visible effect, since
there aren't many 8 byte registers and they all support being written
in two 4 byte parts.
Set the .impl and .valid fields to say that all sizes from 1 to 8
bytes are both valid and implemented by the device.

For VLD3 (single 3-element structure to one lane), there is no
alignment specification and the alignment bits in the instruction
must be zero. This is bit [4] for the size=0 and size=1 cases, and
bits [5:4] for the size=2 case. We do this check correctly in
VLDST_single(), but we write it a bit oddly: in the 'case 3' code we
check for bit 0 of a->align (bit [4] of the insn), and then we fall
through to the 'case 2' code which checks bit 1 of a->align (bit [5]
of the insn) in the size 2 case. Replace this with just checking "is
a->align non-zero" for VLD3, which lets us drop the fall-through and
put the cases in this switch in numerical order.

For VLD1/VST1 (single element to one lane) we are only accessing one
register, and so the 'stride' is meaningless. The bits that would
specify stride (insn bit [4] for size=1, bit [6] for size=2) are
specified to be zero in the encoding (which would correspond to a
stride of 1 for VLD2/VLD3/VLD4 etc), and we must UNDEF if they are
not.
We failed to make this check, which meant that we would incorrectly
handle some instruction patterns as loads or stores instead of
UNDEFing them. Enforce that stride == 1 for the nregs == 1 case.

Currently we incorrectly think that posix_memalign() exists on
Windows. This is because of a combination of:
* the msys2/mingw toolchain/libc claim to have a
__builtin_posix_memalign when there isn't a builtin of that name
* meson will assume that if you have a __builtin_foo that
counts for has_function('foo')
Specifying a specific include file via prefix: causes meson to not
treat builtins as sufficient and actually look for the function
itself; see this meson pull request which added that as the official
way to get the right answer:
https://github.com/mesonbuild/meson/pull/1150
Currently this misdectection doesn't cause problems because we only
use CONFIG_POSIX_MEMALIGN in oslib-posix.c; however that will change
in a following commit.

Currently qemu_try_memalign()'s behaviour if asked to allocate
0 bytes is rather variable:
* on Windows, we will assert
* on POSIX platforms, we get the underlying behaviour of
the posix_memalign() or equivalent function, which may be
either "return a valid non-NULL pointer" or "return NULL"
Explictly check for 0 byte allocations, so we get consistent
behaviour across platforms. We handle them by incrementing the size
so that we return a valid non-NULL pointer that can later be passed
to qemu_vfree(). This is permitted behaviour for the
posix_memalign() API and is the most usual way that underlying
malloc() etc implementations handle a zero-sized allocation request,
because it won't trip up calling code that assumes NULL means an
error. (This includes our own qemu_memalign(), which will abort on
NULL.)
This change is a preparation for sharing the qemu_try_memalign() code
between Windows and POSIX.

We implement qemu_memalign() in both oslib-posix.c and oslib-win32.c,
but the two versions are essentially the same: they call
qemu_try_memalign(), and abort() after printing an error message if
it fails. The only difference is that the win32 version prints the
GetLastError() value whereas the POSIX version prints
strerror(errno). However, this is a bug in the win32 version: in
commit dfbd0b873a in 2020 we changed the implementation of
qemu_try_memalign() from using VirtualAlloc() (which sets the
GetLastError() value) to using _aligned_malloc() (which sets errno),
but didn't update the error message to match.
Replace the two separate functions with a single version in a
new memalign.c file, which drops the unnecessary extra qemu_oom_check()
function and instead prints a more useful message including the
requested size and alignment as well as the errno string.
