hw/intc/arm_gicv3: Add cast to match the documentation
The result of 1 << regbit with regbit==31 has a 1 in the 32nd bit.
When cast to uint64_t (for further bitwise OR), the 32 most
significant bits will be filled with 1s. However, the documentation
states that the upper 32 bits of ICC_AP[0/1]R<n>_EL2 are reserved.
Add an explicit cast to match the documentation.

configure, meson: synchronize defaults for configure and Meson Rust options
If the defaults for --enable-rust ($rust in configure) and Meson's rust
option are out of sync, incremental builds will pick Meson's default.
This happens because, on an incremental build, configure does not run
Meson, Make does instead. Meson then gets the command line options
from either coredata.dat (which has everything cached in Python's pickle
format) or cmd_line.txt (slow path when Meson version is upgraded), but
neither knows about the rust option, and the meson_options.txt default
is used.
This will cause have_rust to be true if rustc is available; and the build
to fail because configure did not put a RUST_TARGET_TRIPLE in config-host.mak.
When in the Rust pull request I changed the $rust default from auto
to disabled, I should have made the same change to meson_options.txt;
do it now.

meson: check in main meson.build for native Rust compiler
A working native Rust compiler is always needed in order to compile Rust
code, even when cross compiling, in order to build the procedural macros
that QEMU uses.
Right now, the check is done in rust/qemu-api-macros/meson.build, but this
has two disadvantages. First, it makes the build fail when the Meson "rust"
option is set to "auto" (instead, Rust support should be disabled). Second,
add_languages() is one of the few functions that are executed even by
"meson introspect", except that "meson introspect" executes both branches
of "if" statements! Therefore, "meson introspect" tries to look for a
Rust compiler even if the option is disabled---and then fails because
the compiler is required by rust/qemu-api-macros/meson.build. This is
visible for example if the compilation host has a stale
scripts/meson-buildoptions.sh and no rustc installed.
Both issues can be fixed by moving the check to the main meson.build,
together with the check for the cross compiler.

audio/pw: Report more accurate error when connecting to PipeWire fails
According to its man page [1], pw_context_connect() sets errno on
failure:
Returns a Core on success or NULL with errno set on error.
It may be handy to see errno when figuring out why PipeWire
failed to connect. That leaves us with just one possible path to
reach 'fail_error' label which is then moved to that path and
also its error message is adjusted slightly.
virtio-gpu: allocate shareable 2d resources on !win32
Similar to what was done in commit 9462ff46 ("virtio-gpu/win32: allocate
shareable 2d resources/images") for win32, allocate resource memory with
memfd, so the associated display surface memory can be shared with a
different process.
gio.pc variable is a bit bogus in context of cross-compilation, since it
contains an absolute path, relative to the sysroot directory. On Fedora, it ends
up as:
/usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig/usr/bin/gdbus-codegen
path which does not exist because it is not shipped by Fedora mingw
packages.
Instead, we can rely on meson find_program() behaviour to do a better
job based on its search order and capabilities.
Use qemu_memfd_alloc() to allocate the display surface memory, which
will fallback on tmpfile/mmap() on systems without memfd, and allow to
share the display with other processes.
This is similar to how display memory is allocated on win32 since commit 09b4c198 ("console/win32: allocate shareable display surface").
ui/win32: fix potential use-after-free with dbus shared memory
DisplaySurface may be free before the pixman image is freed, since the
image is refcounted and used by different objects, including pending
dbus messages.
Furthermore, setting the destroy function in
create_displaysurface_from() isn't appropriate, as it may not be used,
and may be overriden as in ramfb.
Set the destroy function when the shared handle is set, use the HANDLE
directly for destroy data, using a single common helper
qemu_pixman_win32_image_destroy().
When SET_STREAM_FORMAT is called, we should clear the existing setup.
Factor out common function to close a stream.

crypto/hash: Implement and use new hash API
Changes the public hash API implementation to support accumulative hashing.
Implementations for the public functions are added to call the new
driver functions that implement context creation, updating,
finalization, and destruction.
Additionally changes the "shortcut" functions to use these 4 new core
functions.

crypto/hash-afalg: Implement new hash API
Updates the afalg hash driver to support the new accumulative
hashing changes as part of the patch series.
Implements opening/closing of contexts, updating hash data
and finalizing the hash digest.
In order to support the update function, a flag needs to be passed
to the kernel via the socket send call (MSG_MORE) to notify it that more
data is to be expected to calculate the hash correctly.
As a result, a new function was added to the iov helper utils to allow
passing a flag to the socket send call.

tests/qtest: Bump qmp-cmd-test timeout to 120s
The qmp-cmd-test test takes typically about 15s on my local machine.
On the k8s runners it takes usually 20s but sometimes about 60s,
because the k8s runners have wildly variable execution time. If
they're running slow, we hit the default timeout. Bump the
qmp-cmd-test timeout to 120s to avoid this.

chardev: introduce 'reconnect-ms' and deprecate 'reconnect'
The 'reconnect' option only allows to specify the time in seconds,
which is way too long for certain workflows.
We have a lightweight disk backend server, which takes about 20ms to
live update, but due to this limitation in QEMU, previously the guest
disk controller would hang for one second because it would take this
long for QEMU to reinitialize the socket connection.
Introduce a new option called 'reconnect-ms', which is the same as
'reconnect', except the value is treated as milliseconds. These are
mutually exclusive and specifying both results in an error.
'reconnect' is also deprecated by this commit to make it possible to
remove it in the future as to not keep two options that control the
same thing.
