[dbapi] retire repo.entity_metas which was used by the dbapi Related to #3933480.

[dbapi] retire repo.execute, which was used by the dbapi We will retire or reform pieces, mostly of the Repository class, that were related to the old dbapi way of life. Related to #3933480.

[devtools/testlib] remove dbapi backward-compat Related to #3933480.

[test] fix copy-pasta in doc string

[book] remove dbapi documentation Move some still-relevant doc related to the RQL connection API to the 'sessions' section. It might make sense to move this back outside of the "Repository development" chapter at some point since this is relevant in other contexts.

[uilib] `uilib.js` helper now honors explicit JSString (closes #4959538) Previously, if a JSString was inside a nested container (i.e. list or dict), it was handled as a string, not a verbatim js chunk (see docstring and test). So the following code:: >>> str(js.cw.pouet(1, {'callback': JSString('cw.mycallback')}) resulted in:: "cw.pouet(1, {'callback': 'cw.mycallback')})" while we expect (note the removed quotes):: "cw.pouet(1, {'callback': cw.mycallback)})" We use ``cubiweb.utils.js_dumps`` instead of ``cubicweb.utils.json_dumps`` which is aware of JSString.

[dbapi] remove the dbapi module and its immediate remaining users We suppress toolsutils.config_connect, which has currently only one known user (the email cube), which is being patched. It can be replaced with utils.admincnx function for a local access. Next will come a series to: * remove the session backward compatibility * fold ClientConnection into Connection Closes #3933480.

[web/views] remove dbapi usage from 'gc' view

[sqlite] Fix integrity error parsing Up to sqlite 3.7, integrity error message may be in the singular form if only one column is in the unique index. Closes #5224632

[postgres] fix limit_size regexp to properly remove one char tags like <p>. Closes #5221847

[postgres] _regproc.postgres.sql should be reloadable

[mail] include Date header in generated mails (closes #5271058) Mails without Date gets flagged as spam. Plus it's wrong anyway.

[doc] mention datadir-url configuration option in release notes Related to #5204550

[web] add test for datadir-url option (related to #5204550)

[web] Add datadir-url configuration option (closes #5204550) Makes it possible to use a different host for static data instead of ${base_url}/data

[web] kill https-deny-anonymous option (closes #5193687) It doesn't make much sense to prevent people from using https.

[cwctl] don't filter DeprecationWarnings

[exceptions] avoid calling UniqueExceptionError.rtypes after closing the session

[web/test] Fix broken tests after commit b81adb5e32f9 Add missing n3rdf view to RDF view list.

[web/test] don't delete uicache directory Other tests use it, so the rmtree was a bit too much. Set CACHEDIR to a temporary subdirectory, and only delete that.

[web/views] add text/n3 rdf view Less shit than xml.

[schemas] make CWEType.final default to False (closes #5049201)

[repository] replace session with cnx in a few places

Don't pass an encoding to rqlst.as_string()

[rset] Deprecate the 'encoded' argument to ResultSet.printable_rql() It's hardly used at all, and when used inside CubicWeb, it's only set as false. Better make sure that this function always returns a proper unicode string and let the caller handle conversion on its own.
