b723eeb815 monitor: move monitor_data_(init|destroy) into QOM init/finalize 
Start to take advantage of QOM, by using object init and finalize
methods to replace monitor_data_init and monitor_data_destroy.

A standalone helper is provided to enable the I/O thread for QMP
where appropriate for the chardev backend.

ae286229f4 monitor: remove 'skip_flush' field 
The 'skip_flush' field is set on the dummy throwaway HMP monitor
object created by QMP's  'human-monitor-command', as an indication
not to try to write data to the chardev. Instead the QMP command
impl will grab the data straight out of the in-memory buffer.

The flag is redundant, however, as the monitor code could instead
simply check the 'fe_is_open' field on the CharFrontend, which
will be false in the same scenarios that 'skip_flush' is true.

f96eac8a4f monitor: minimal conversion of monitors to QOM 
This introduces abstract QOM type "monitor", with concrete subtypes
"monitor-hmp" and "monitor-qmp". This is the bare minimum conversion
of just the type declarations and replacing g_new/g_free with
object_new/object_unref.

Command line option "-monitor" now creates a "monitor-hmp" object
"/objects/compat_monitorNNN" in addition to the character device
"/chardevs/compat_monitorNNN". NNN counts up from zero.

Exception: "-monitor chardev:ID" creates a "monitor-hmp" object
"/objects/ID", and does not create a character device.

"-qmp" and "-qmp-pretty" work the same, except they create a
"monitor-qmp" object.

"-mon" now creates either a "monitor-hmp" or "monitor-qmp" object
"/objects/ID" if the option argument provides an ID, else
"/objects/compat_monitorNNN".

"-gdbstub" and "-serial mon:..." now create a "monitor-hmp" object
"/objects/compat_monitorNNN".

Note that the object's name in "/objects/" matches the QemuOpts ID when
it exists.  The only cases where it doesn't exist are "-mon" without ID,
"-gdbstub" and "-serial mon:".

A future patch will make "monitor-hmp" and "monitor-qmp" work with
"-object" and "object-add".

Note: there is a slight change in the NNN values assigned. The old
code would increment the counter for every monitor added (except for
-mon, -serial mon:..., -gdbstub), regardless of whether it needed a
"compat_monitorNNN" ID assignment. Now it is only incremented when an
automatic ID assigned is needed (but even for -mon, -serial mon:...,
-gdbstub).

9c3b2c9db5 qom: replace 'can_be_deleted' with 'prepare_delete' 
While most objects can perform all their cleanup in the finalizer
method, there can be interactions with other resources / subsystems
/ threads which require that some cleanup be performed on an user
creatable object before unparenting it and entering finalization.

The current 'can_be_deleted' method runs in the deletion path and
is intended to be used to block deletion. While it could be used
to perform cleanup tasks, its name suggests it should be free of
side-effects.

Generalize this by renaming it to 'prepare_delete', explicitly
allowing for cleanup to be provided. Existing users of 'can_be_deleted'
are re-written, which provides them with more detailed/tailored error
messages.

ce0b7a15bc accel/mshv: Fix pointer to proc feature bitfield 
Processor features are stored in a union containing two "banks":

union hv_partition_processor_features {
    uint64_t as_uint[2];
    struct {
        uint64_t sse3_support:1;
        ...
    }
}

get_proc_features() to retrieve the 2nd bank was passing a pointer that
steps over the whole union (+16B) instead of picking the 2nd bank _in_
the union. This manifests in mismatching feature bits for the 2nd bank
and possibly other side-effects caused by writing beyond the union.

We need to step over the first bank (+8B) by using as_uint64[0/1] to
correct this behaviour.
