[repoapi] fold ClientConnection into Connection
Connection replaces ClientConnection everywhere.
Some notes:
* testlib: .client_cnx and .repo_cnx become aliases of .cnx (we might
not want to tell people to update their tests again for just no real
benefit, so we'll live with these aliases for a while)
* entity.as_rset must not be cached because we risk caching result
sets having a Connection object as .req (helps unittest_breadcrumbs)
* entity._cw_dont_cache_attributes loses its repo/request special
paths and only keeps its storage/bfss user (this helps
unittest_wfobjs)
* moreover, entity.cw_instantiate and .cw_set stop overriding the
attributes cache *after* the before_*_entity hooks have run, because
there is no need to (it is now actually harmful to do it and
unittest_hooks.test_html_tidy* tests remain green because of this)
* rset._build_entity sticks its .req onto the entity just fetched from
the cache, because otherwise it might carry a _cw that is a
Connection object where a Request is expected (helps
unittest_views_actions)
* we get overall better cache usages (entity caches were split over
Request + ClientConnection and Connection), hence the changes
unittest_entity and unittest_wfobjs
* void the ecache when providing the cnx to a request object
Having the entity cache pre-filled when we bind it to the request
object hurts because these entities are bound to Connection objects,
that lack e.g. `.form` or `.add_js` and crash the views subsystem.
Thus, the unittest_testlib.test_error_raised test will are kept
green.
