[req] make rebuild_url predictable Fixes test with python -R. Related to #4959402.

[web/test] don't depend on iteration order on a set Fixes test under python -R ('pending_insert' in session data is a set, so we can't rely on any particular ordering). Related to #4959402.

[web/test] fix cubicweb 3.19 deprecation warning

[web/test] use unicode instead of str for user logins makes lgdb/sqlite quieter.

[entities] make cw_fti_index_rql_queries predictable Don't depend on the hash function, fixing test with python -R. Related to #4959402.

[hooks/syncschema] use a list instead of a set for UpdateFTIndexOp The order in which etypes get indexed matters. Related to #4959402.

[rqlrewrite] sort possible types when turning is_instance_of into is Helps get predictable output even with python -R. Related to #4959402.

[server/test] use unicode strings for user logins

[web/test] use unicode object as user login (py.warnings) WARNING: /home/jcr/src/cw/cubicweb/devtools/testlib.py:206: DeprecationWarning: Sanitizing an input dictionary with str values, please check your data (key = 'login')

[server/querier] stop passing a rqlst to empty_rset (py.warnings) WARNING: /home/jcr/src/cw/cubicweb/server/querier.py:46: DeprecationWarning: [3.20] rqlst parameter is deprecated return ResultSet([], rql, args, rqlst=rqlst)

[web/views] Use predictable ordering for attributes in entity XML view Fixes test under python -R. Related to #4959402.

[web/views] set explicit order for ManageSourcesAction Gives predictable ordering wrt ManageUsersAction under python -R. Related to #4959402.

[web/test] don't depend on dict iteration ordering Fixes tests under python -R. Related to #4959402.

[web/test] pass login as unicode string silences lgdb/sqlite warning.

[web/test] fix 3.19 deprecation warning

[sobjects/test] Fix dependency on predictable hashing Fix test under python -R by ignoring url query parameter ordering. Related to #4959402.

[test] don't rely on a stable ordering for appobject_path Fixes test under python -R. Related to #4959402.

[server] remove "standalone RQL server" from possible configuration choices Related to #2919297.

Remove leftover bits from start-repository command, and document its demise Related to #2919297

Remove the remote repository-access-through-zmq support Modern methods such as the rqlcontroller cube + the cwclientlib library are the way forward. Closes #2919297.

Remove remote repository-access-through-pyro support Modern methods such as the rqlcontroller cube + the cwclientlib library are the way forward. Closes #2919309.

[web/views/rdf] Take the second element of XY equivalent for non final relation When given a Yams snippet of the form `<etype> <rtype>` ``xy.xeq()`` will return the XML snippet equivalent to this relation in the form of a tuple `(subject, rtype, object)` so ``item`` will always be a tuple here. In fact, the correct code appears just a few lines above (around line 88) for final relations so I guess this is a copy-paste mistake. Closes #4745929.

[server] Make sure 'zmq-address-sub' config is always iterable

[web] split timeline in an individual cube Closes #1279544

[devtools] don't hide warnings and errors during tests The markdown module in jessie turns all warnings into logging calls, so this allows me to still see deprecation warnings when running tests.
