2022-01-28rtc: Move RTC function prototypes to their own headerPeter Maydell1-1/+1
softmmu/rtc.c defines two public functions: qemu_get_timedate() and qemu_timedate_diff(). Currently we keep the prototypes for these in qemu-common.h, but most files don't need them. Move them to their own header, a new include/sysemu/rtc.h. Since the C files using these two functions did not need to include qemu-common.h for any other reason, we can remove those include lines when we add the include of the new rtc.h. The license for the .h file follows that of the softmmu/rtc.c where both the functions are defined.

2021-02-08qom: Allow optional sugar propsGreg Kurz1-1/+2
Global properties have an @optional field, which allows to apply a given property to a given type even if one of its subclasses doesn't support it. This is especially used in the compat code when dealing with the "disable-modern" and "disable-legacy" properties and the "virtio-pci" type. Allow object_register_sugar_prop() to set this field as well.
