[web/component] guard against invalid page_size form parameter Same as dff28956f37e, except the almost same code exists in two places (yay us).

[predicates] fix paginated_rset for components that change page_size_property The predicate and component had better agree on the page size.

[devtools] fix get_bounds Say an attribute has two IntervalBoundConstraints, one with minvalue=0 and the other with maxvalue=10 (not literally, or that could be a single constraint, but e.g. with references to other attributes). We don't want to override the minvalue of the former with None just because the latter happens last in the constraints list. This doesn't fix the case where two constraints both have a min or a max value. Meh.

[devtools] "fix" boundary condition for autofill maxvalue in an IntervalBoundConstraint is inclusive. If the min and max values happened to coincide, we would call random.choice on an empty list, which it didn't like. This is still broken in the case of BoundaryConstraint('>', minvalue), as we assume the minvalue is in the range, but that's something for another time.

[test] Use stdlib doctest module instead of logilab-common class The former just works fine now but the later does not play well with py.test.

[test] Re-implement generative tests with subtests

[devtools] Re-implement generative tests using subtests Generative tests as implemented in logilab.common.testib are not compatible with tests runner other than lgc.pytest and this implementation differs from the standard library, which has support for subtests_ since Python 3.4. Use unittest2 to bridge the gap. Maybe it'd be good to implement this on logilab.common.testlib side at some point. Let's see how this gets received here first. .. _subtests: https://docs.python.org/3/library/unittest.html#subtests

cleanups

[pkg] python-tz does not exist in centos should be pytz (closes #10290056)

[test] Skip LDAP tests if any of the underlying programs is not found Some programs are in ldap-utils or ldapscripts, which may not be installed despite slapd may. Follow-up on 282880f81311.
