[time zone] support for TZDatetime and TZTime data type Should be usable and cause no crash, though some stuff may still be refined (test value generation, display in views/forms...) Proprify some data structures dealing with yams base types along the way and adding warning when some were missing (eg Interval usually).

merged test fix from stable

[http] implement 1587305: provide better implementation of Accept header parsing + tests

[web test] extract a set_auth_mode method from init_authentication and use it in test_fb_login_concept to avoid bad test interaction

merge stable to default

fix failing tests before 3.12 release added a skip in unittest_reledit, I'd like acampeas to give it a look.
