[FIX] orm: during update of ir.model and ir.model.fields, mark xmlid's to force unlink() of deleted models and columns.
[FIX] ir.model.data: during cleanup of deleted xmlid's, also delete ones with noupdate set to NULL, force unlink() of ir.model and ir.model.fields records, log xmlid of deleted records.
[FIX] do not set the category of modules at initialization. Wait the registry to be available to allow tracking of generated xmlids
[IMP] create_categories(): avoid a useless query as we already know the xmlids
[IMP] ir.model: new field table_name, allow deletion of table and views that are not in the registry
