[cwconfig] load appobjects subpackages recursively This is a regression appeared in 3.25.0. Appobjects (entities, views etc) subpackages should be loaded recursively, this is the historical behavior, relevant code is in logilab.common.registry._toload_info(). To keep historical behavior schema subpackages should not be loaded, relevant code is in yams.reader.get_schema_files(). We may want to have a consistent behavior later on... Closes #17073706.

[pkg] Set version to 3.26.0.dev0

Merge with 3.25 branch

[pkg] Version 3.25.0

[entities] Fix backward compat of IDublinCore adapter wrt dc_long_title `entity.dc_long_title()` used to fallback to `dc_title()`, and most entity types were relying on this, thus only implementing the later. Since introduction of the IDublinCore adapter, if one call `entity.dc_long_title()` on an entity that only implements `dc_title()`, it will retrieve the adapter which will then call its own `title()` method instead of the `dc_title()` method of the entity as expected. Fix this by calling instead `entity.dc_title()` which will eventually kick in the backward compat layer if necessary.

[web] Do not try to rmtree symlinks in rmtreecontent() There is a symlink in data directory (created by generate_static_dir() method) and trying to rmtree() it will fail with an OSError. So we unlink() it instead.

[pkg] Version 3.25.0rc3
