[config] turn internal configuration methods building appobjects search path into normal method rather than class method as this is useless and make path filters difficult to override (we had to override the class attribute, as instance attributes were not seen). Also rename related methods for consistency with current vocabulary

fix missing import

backport stable

[hooks/syncshema] fix logging level and nicer message (wrong changeset published previously)

[hooks/syncschema] do not crash on DROP of an already dropped index/... (closes #2465393)

[cwctl] show a better diagnostic message on version violation (closes #2464800)

[tabs] fix pb with non-lazy tabs: style isn't properly set due to missing jquery.ui activation. Closes #2465657 also do a small cleanup on the way, and properly implements render_entity rather than cell_call, as one would expect regarding default PrimaryView code.

[migration] fix backward compat for rename_relation

[datafeed] make cnxset handling of datafeed source more robust currently we may run in some cases where the session has no more cnxset depending on errors and parser's handling of the cnxset. Also, free the cnxset and reacquire it later, letting a chance to other threads to run.

don't use rset.rowcount in predicates, this makes them usable with other types such as lists
