mod_csi_simple: Disable revert-to-inactive timer when going to active mode This timer shouldn't kick in in the middle of active mode.

mod_csi_simple: Clear delayed active mode timer on disable It should not be there afterwards. Noticed that it seems to fire some time after resumption claiming that the queue size is nil, implying that it may hold a reference to an expired session somehow.

mod_admin_shell: Refactor 'cert' column Removes some dead code and hopefully simplifies a bit. There's a tree of possibilities with the two tri-state status properties, something like chain: * nil -- cert validation disabled? * invalid -- something wrong with the chain (including ee cert) * valid -- chain ok cert: * nil -- incomplete validation?? * invalid -- mismatched names or such * valid -- all good!

util.jsonschema: Fix UTF-8ness of 'minLength' and 'maxLength'

util.jsonschema: Implement 'minContains' and 'maxContains'

util.jsonschema: Add some comments wrt Lua-specifics

util.jsonschema: Implement 'luaPattern' - Lua variant of 'pattern' Like 'pattern' but uses Lua patterns instead of Regular Expressions, since only a subset of regex are also valid Lua patterns.

util.jsonschema: Implement 'luaPatternProperties' as Lua variant of 'patternProperties' Previous version of this patch used 'patternProperties' but that would only work with simpler ECMA-262 regular expressions are also valid Lua patterns.

util.jsonschema: Tweak description of disabled test This doesn't fail because of additionalProperties, looks more like some issue with recursive definitions and util.jsonpointer that I don't want feel like investigating now.
