qom: add helpers for UserCreatable object types
The QMP monitor code has two helper methods object_add
and qmp_object_del that are called from several places
in the code (QMP, HMP and main emulator startup).
The HMP and main emulator startup code also share
further logic that extracts the qom-type & id
values from a qdict.
We soon need to use this logic from qemu-img, qemu-io
and qemu-nbd too, but don't want those to depend on
the monitor, nor do we want to duplicate the code.
To avoid this, move some code out of qmp.c and hmp.c
adding new methods to qom/object_interfaces.c
- user_creatable_add - takes a QDict holding a full
object definition & instantiates it
- user_creatable_add_type - takes an ID, type name,
and QDict holding object properties & instantiates
it
- user_creatable_add_opts - takes a QemuOpts holding
a full object definition & instantiates it
- user_creatable_add_opts_foreach - variant on
user_creatable_add_opts which can be directly used
in conjunction with qemu_opts_foreach.
- user_creatable_del - takes an ID and deletes the
corresponding object
The existing code is updated to use these new methods.
