util.datamanager: Reduce log level of left over debug messages to debug (thanks Trung) These were mostly 'warn' to make them stand out from the debug noise

util.datamanager: Fix missing separator in log line

Merge 0.12->trunk

core.certmanager: Update Mozilla TLS config to version 5.7 Ref https://github.com/mozilla/server-side-tls/issues/285

mod_pubsub: Send correct jid attribute in disco#items Fixes use in PEP where the JID does not equal the bare domain.

mod_http_file_share: Put 'expires' back, thought it was unused Removed in 536055476912 because it was not used anywhere else in the file, but per the documentation it is meant to inform external upload services of the expiry time of the upload itself.

util.cache: Pass cache itself to eviction callback Simplifies access to the cache without moving code around a lot given the currently common pattern of local some_cache = cache.new(size, function(k,v) end)

util.cache: Keep eviction candidate if callback resized to make room Previously either the old or the new values would be rejected, even if the cache was resized to allow more items.

util.serialization: Teach Teal about the new "pretty" preset

util.jsonpointer: Change function prototype to allow anything But anything that's not a table can't be resolved into, which could happen in the middle, so eh.
