[dataimport] remove _rql heresy 1) ObjectStore knows nothing about rql, it just drops it on the floor 2) RQLObjectStore has a session, it can run rql that way 3) setting an object's "_rql" attribute is not a reasonable user-facing interface Also drop _commit attribute from base ObjectStore, it doesn't use it.

[dataimport] remove dead code The only caller of ObjectStore._put is ObjectStore.create_entity, which RQLObjectStore overrides (and doesn't call up).

Remove uses of logilab.common.compat.{all,any} They're just aliases to the builtin ones on python 2.5+. If anyone needs convincing: >>> from logilab.common import compat >>> compat.any <built-in function any> >>> compat.all <built-in function all>
