[entity] add an official ``cw_etype`` property for entity This property holds the CWEtype id of the entity. This information was previously available through __regid__ but this is an ugly public API. So we have a new clean public API. The ``dc_type()`` method could not be used as it is translated. (closes #2793792)

[notification] use new style operation for notification This results in far less operations created. Operation creation is expensive. We keep some compatibility with the previous API because some cubes have been reported to use it.

[cleanup] drop code deprecated since 3.6 The 3.6 API have been dropped some time ago. Those three lines survived the purge. One of them is even deprecated since 3.5.

[notification] fix documentation The doc say precommit, the code says postcommit. The code is right. We also clarify the documentation of another related operation looking suspiciously wrong but actually correct.

[ldapuser] Deprecated the source We have ldapfeed for some time. maintaining both is cumbersome. This old style source will be dropped in 3.18. closes #2567712

[rql2sql] Remove an XXX by explaining why Int non-substitution is desired (in the current state of the API)

[rql2sql] Boolean values should be substitued like others. Closes #2829481 Furthermore lgdb 1.10 deprecate boolean_value method and this simplify testing.

[toward-py3k] rewrite __cmp__ (closes #2715115) In Python 3k `__cmp__` special method is no longer supported. So we split it in `__lt__` and `__eq__`. details on Python3k behavior here: http://docs.python.org/3.0/whatsnew/3.0.html#ordering-comparisons

skeleton: add RPM spec template (closes #2800884)

[clean_session] revert itervalues usage from 0bb18407c053 self.close(session) changes the self._sessions content. We need to create a full list of value before starting closing them.
