Return a Result<()> from the method, and "unwrap" it into error_fatal
in the caller.

Marc-André LureauandPaolo Bonzini 1b21518f73 char: rename CharBackend->CharFrontend
The actual backend is "Chardev", CharBackend is the frontend side of
it (whatever talks to the backend), let's rename it for readability.

Martin KletzanderandPaolo Bonzini 80a3c9c01a rust: remove useless glib_sys bindings
The definition of types needed for g_autolist(), g_autoslist(),
g_autoqueue() need the imports for GList, GSList and GQueue
to appear everything.  Rust code is never going to see those,
since they are not used in structs.  Block the types from
appearing in the bindings.

Paolo Bonzini 2a8a7bb8aa rust: qdev: const_refs_to_static
Now that const_refs_static can be assumed, convert the members of
the DeviceImpl trait from functions to constants.  This lets the
compiler know that they have a 'static lifetime, and removes the
need for the weird "Box::leak()".

Paolo Bonzini dcdee1e718 rust: vmstate: use const_refs_to_static
The VMStateDescriptionBuilder already needs const_refs_static, so
use it to remove the need for vmstate_clock! and vmstate_struct!,
as well as to simplify the implementation for scalars.

If the consts in the VMState trait can reference to static
VMStateDescription, scalars do not need the info_enum_to_ref!
indirection and structs can implement the VMState trait themselves.

Zhao LiuandPaolo Bonzini 7da9ee9207 rust: vmstate: convert to use builder pattern
Similar to MemoryRegionOps, the builder pattern has two advantages:
1) it makes it possible to build a VMStateDescription that knows which
types it will be invoked on; 2) it provides a way to wrap the callbacks
and let devices avoid "unsafe".

Unfortunately, building a static VMStateDescription requires the
builder methods to be "const", and because the VMStateFields are
*also* static, this requires const_refs_static.  So this requires
Rust 1.83.0.

Manos PitsidianakisandPaolo Bonzini a71df7e143 rust: add qdev Device derive macro
Add derive macro for declaring qdev properties directly above the field
definitions. To do this, we split DeviceImpl::properties method on a
separate trait so we can implement only that part in the derive macro
expansion (we cannot partially implement the DeviceImpl trait).

Adding a `property` attribute above the field declaration will generate
a `qemu_api::bindings::Property` array member in the device's property
list.
