in the caller.

Paolo Bonzini 56dbf087a8 rust/util: add ensure macro 
The macro is similar to anyhow::ensure but uses QEMU's variation
on anyhow::Error.  It can be used to easily check a condition
and format an error message.

Zhao LiuandPaolo Bonzini 59d8f86442 rust/qemu-macros: Convert bit value to u8 within #[property] 
For bit property, make the type conversion within the #[property] macro
so that users do not need to handle the conversion.

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.

HPET ids for fw_cfg are not assigned correctly, because there

After HPET's #property conversion, there's no use case for
declare_properties & define_property. So get rid of them for now.

In future, if there's something that #property really cannot resolve,
they can be brought back.

Zhao LiuandPaolo Bonzini 9686aa9a05 rust/qdev: Support bit property in #property macro 
Add BIT_INFO to QDevProp trait, so that bit related property info could
be bound to u32 & u64.

Then add "bit=*" field in #property attributes macro to allow device to
configure bit property.

In addtion, convert the #property field parsing from `if-else` pattern
to `match` pattern, to help readability. And note, the `bitnr` member of
`Property` struct is generated by manual TokenStream construction,
instead of conditional repetition (like #(bitnr: #bitnr,)?) since
`quote` doesn't support this.

In addtion, rename VALUE member of QDevProp trait to BASE_INFO.

And update the test cases about qdev property.
