doap: Update reference for publishing of XEP-0478: Stream Limits Advertisement

mod_c2s,mod_s2s: Fix tag name for SLA (thanks mjk) The (still not published) XEP-xxxx: Stream Limits Advertisement uses the element <max-bytes/> to advertise the maximum octet size of top level stream elements. "size" was probably a leftover of an even earlier version of the (Proto)XEP.

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!
