[PATCH v2 0/4] Improve default object property_add uint helpers

[Felipe Franciosi <felipe@nutanix.com>]

This improves the family of object_property_add_uintXX_ptr helpers by enabling
a default getter/setter only when desired. To prevent an API behavioural change
(from clients that already used these helpers and did not want a setter), we
add a OBJ_PROP_FLAG_RD flag that allow clients to only have a getter. Patch 1
enhances the API and modify current users.

While modifying the clients of the API, a couple of improvement opportunities
were observed in ich9. These were added in separate patches (2 and 3).

Patch 3 cleans up a lot of existing code by moving various objects to the
enhanced API. Previously, those objects had their own getters/setters that only
updated the values without further checks. Some of them actually lacked a check
for setting overflows, which could have resulted in undesired values being set.
The new default setters include a check for that, not updating the values in
case of errors (and propagating them). If they did not provide an error
pointer, then that behaviour was maintained.


Felipe Franciosi (4):
  qom/object: enable setter for uint types
  ich9: fix getter type for sci_int property
  ich9: Simplify ich9_lpc_initfn
  qom/object: Use common get/set uint helpers

- Update sci_int directly instead of using stack variable
- Defining an enhanced ObjectPropertyFlags instead of just 'readonly'
- Erroring out directly (instead of using gotos) on default setters
- Retaining lack of errp passing when it wasn't there
