QOM boilerplate cleanup

Documentation build fix:
* memory: Remove kernel-doc comment marker (Eduardo Habkost)

QOM cleanups:
* Rename QOM macros for consistency between
  TYPE_* and type checking constants (Eduardo Habkost)

QOM new macros:
* OBJECT_DECLARE_* and OBJECT_DEFINE_* macros (Daniel P. Berrangé)
* DECLARE_*_CHECKER macros (Eduardo Habkost)

Automated QOM boilerplate changes:
* Automated changes to use DECLARE_*_CHECKER (Eduardo Habkost
* Automated changes to use OBJECT_DECLARE* (Eduardo Habkost)
