[schema/security] add __hash__ to rql expression. Closes #3013535 This is required so that when some rql expression participate to a dictionary key, only the expression is considered (consistent with comparison). This behaviour is expected in security at least, see the related bug for instance. This scramble msplanner unit tests a bit.

[web/views/staticcontrollers] Make ConcatFilesHandler write to a tempfile In order to be more resistant to errors such as ENOSPC, and against different threads accessing the same static data, we: - concatenate data files to a temporary file, and rename it once we're done - delete the tempfile in case of errors - protect the creation of the cache_concat file with a lock Closes #3005547

[test] make unittest_schema.py compatible with cubicweb-file 0.14
