Rename the field 'osv_memory' on 'ir.model' into 'transient', and make it a
regular field instead of a computed one. When instantiating a custom model,
use its value to make transient models.
This commit alone will make your server crash on an existing database. A small
database migration is needed: simply add a boolean column `transient` (with
default value false) in table `ir_model`.
