Adjust count_cpreg and add_cpreg_to_list to be used with
g_hash_table_foreach instead of g_list_foreach. In this way we have
the ARMCPRegInfo pointer directly rather than having to look it up
from the key.
Delay the sorting of the cpreg_indexes until after add_cpreg_to_list.
This allows us to sort the data that we actually care about,
the kvm id, as computed within add_cpreg_to_list, instead of
having to repeatedly compute the kvm id within cpreg_key_compare.

The passt networking backend uses functions from the GIO library,
such as g_subprocess_launcher_new(), to manage its daemon process.
So, building with passt enabled requires GIO to be available.
If we enable passt and disable gio the build fails during linkage with
undefined reference errors:
/usr/bin/ld: libsystem.a.p/net_passt.c.o: in function `net_passt_start_daemon':
net/passt.c:250: undefined reference to `g_subprocess_launcher_new'
/usr/bin/ld: net/passt.c:251: undefined reference to `g_subprocess_launcher_take_fd'

/usr/bin/ld: libsystem.a.p/net_passt.c.o: in function `net_passt_start_daemon':
net/passt.c:269: undefined reference to `g_subprocess_get_exit_status'
Fix this by adding an explicit weson dependency on GIO for the passt
option.
The existing dependency on linux is kept because passt is only available
on this OS.

If the guest feeds invalid data to the UHCI controller, we
can assert:
qemu-system-x86_64: ../../hw/usb/core.c:744: usb_ep_get: Assertion `pid == USB_TOKEN_IN || pid == USB_TOKEN_OUT' failed.
(see issue 2548 for the repro case). This happens because the guest
attempts USB_TOKEN_SETUP to an endpoint other than 0, which is not
valid. The controller code doesn't catch this guest error, so
instead we hit the assertion in the USB core code.
Catch the case of SETUP to non-zero endpoint, and treat it as a fatal
error in the TD, in the same way we do for an invalid PID value in
the TD.
This is the UHCI equivalent of the same bug in OHCI that we fixed in
commit 3c3c233677 ("hw/usb/hcd-ohci: Fix#1510, #303: pid not IN or
OUT").
This bug has been tracked as CVE-2024-8354.

We only need invalidate tbs from a single page, not flush
all translations.

The tb_flush within write_misa was incorrect. It assumed
that we could adjust the ISA of the current processor and
discard all TB and all would be well. But MISA is per vcpu,
so globally flushing TB does not mean that the TB matches
the MISA of any given vcpu.
By recording misa in the tb state, we ensure that the code
generated matches the vcpu.

Since 288a5fe980, we don't link translation blocks
directly to palcode entry points. If we load palbr
from env instead of encoding the constant, we avoid
all need for tb_flush().

When we remove dest from orig's links, we lose the link
that we rely on later to reset links. This can lead to
failure to release from spinlock with self-modifying code.

Using phrasing from https://openinfra.org/legal/ai-policy (with just
"commit" replaced by "submission", because we do not submit changes
as commits but rather emails), clarify that the contributor remains
responsible for its copyright or license status.
[This is not my preferred phrasing. I would prefer something lighter
like "the "Signed-off-by" label in the contribution gives the author
responsibility". But for the sake of not reinventing the wheel I am
keeping the exact words from the OpenInfra policy.]

QEMU's AI generated content policy does not flesh out the exception
process yet. Do it, while at the same time keeping things informal: ask
contributors to explain what they would like to use AI for, and let them
reach a consensus with the project on why it is credible to claim DCO
compliance in that specific scenario.
In other words, exceptions do not "solve the AI copyright problem". They
take a position that a reasonable contributor could have, and assert that
we're comfortable with the argument.

The AI policy in QEMU is not about content generators, it is about generated
content. Other uses are explicitly not covered. Rename the policy and clarify
its scope in the TL;DR section, as a matter of convenience to the reader.

Children are automatically unparented so manually unparenting is
unnecessary.
Worse, automatic unparenting happens before the instance_finalize()
callback of the parent gets called, so object_unparent() calls in
the callback will refer to objects that are already unparented, which
is semantically incorrect.
