remove 3.9 bw compat
In cw 3.9, interfaces are deprecated and replaced with adapters,
yielding a lot of bw compat in many places -- most if this patch is
concerned with the interface bw compat
- cwvreg: interface cleanup
- doc/adapters.rst: interface cleanup
- entities/adapters.py, wfobjs.py: interfaces bw compat
- entity.py: interfaces bw compat, also get_value, delete,
attr_metadata, has_perm, set_related_cache, clear_related_cache,
clear_related_cache, related_rql
- predicates.py: score_interfaces & implements
- interfaces.py & mixins.py: 100% gone
- view.py: implement_adapter_compat, unwrap_adapter_compat
- calendar.py, editcontroller.py, ibreadcrumbs.py, navigation.py, xmlrss.py:
interface bw compat
- treeview.py: salvage one function from mixins.py
