[debian] move unittest2 to requires not recommends closes #16404515

[devtools] named context for boxes subTest for consistency

Added tag 3.24.3, debian/3.24.3-1, centos/3.24.3-1 for changeset bb5904cd284e

[pkg] 3.24.3

[cwconfig] ensure CubicWebNoAppConfiguration returns a typed value (closes #16364459)

[views/optimization] Makes has_editable_relations predicate less costly by using generator The `has_editable_relations` predicate is used to say if the 'modify' action should appear. To do so, it checks if anything is editable (ie. something in the attributes, relations or inlined section of the automatic form). This may be costly since it may have to check several permissions. To optimize this a bit, this cset turns list into generator so that we'll avoid unnecessary work as soon as we find a match.

[cwconfig] Trim down allowed exceptions in gettext language setting I can't see any valid reason to pass on ImportError and AttributeError. In particular, the latter shadowed a Python 3 error until 4f43e64603ef.

[pkg] Configure "universal" wheel build According to https://packaging.python.org/distributing/#wheels, we should create universal wheels (no 2to3 step, no C extension). Configure this in setup.cfg. [ci skip]

[rqlrewrite] Test and fix potential NameError We were referencing a loop variable, which may lead to a name error and show a potential error if there are several matching variables. To avoid this, introduce a list to hold every encountered variable and process all of them later.
