[js/widgets] fix the InOut widget with modern jQuery versions Several things are done there: * reduction in size and complexity of the code * the unused defaultsettings are removed * the initial `unlinked` list is now correctly populated from python-side * the unit test is adjusted because it tested an irrelevant implementation detail which is no longer true (but the widget of course still handles correctly the linkto information) Tested with ie7, ie9, chromium, firefox. Tested with jQuery 1.6 (cw 3.17.x) and 1.10. Closes #3154531.

[autoform] Allow overridding of permissions checks Closes #3063930

[schema] fix unique together index handling We now provide a more compact indexname, using the schema constraint entity type and the position of the columns set in the entity type unique constraints list. This avoids a nasty name truncation issue. The UniqueTogetherError object is made smarter: it computes the rtypes, abstracting the underlying backend (pg/sqlserver vs sqlite). The `user friendly` adapter is much simplified since there is no longer any truncation issue. Uses a new logilab.database version (ticket #151507) and a new yams version (ticket #189299) Closes #2514939 [jcr: disable hooks when temporarily dropping CWUniqueTogetherConstraint entities]

[pyrorql] deprecate pyrorql source (closes #2919299)

[web/facet] do NOT drop offset/limit of the base rql (closes #3344579)

[webctl] Generate static data directory on upgrade (closes #2167873) - if the folder already exists, ``upgrade`` asks for deletion, - add an option (``generate-staticdir``) to allow skipping this task. - add an option (``staticdir-path``) to specify the static data folder path. The ``gen-static-datadir`` command allows to specify the target folder but there is otherwise no way to retrieve this information during upgrade.

[cwctl] Don't check for old lgc versions Support for check_duplicated_command in CommandLine was added in 2011 for 0.55, and we already depend on 0.59.0.

[migration/3.18] add sanity checks before changing symmetric relations Delete supposedly impossible relations from the db. Related to #3259713.

[migration/3.18] disable all hooks when setting up symmetric relations This operation is semantically a no-op, so it should be invisible for the application. Related to #3259713.

[devtools] bases for instrumenting / debugging standard propagation hooks * a class that helps writing command to check propagation, detecting standard errors and picture the propagation as a graph * a class to instrument sets used to configure standard propagation hooks closes #3171980
