plugins: Update for namespace bump in XEP-0353 v0.4.0

util.prosodyctl.check: Fix reset of libunbound before DNS checks Probably worked anyway but settings might not always have been applied depending on what order things happens in. Error was hidden by the pcall, which was sorta intentional...

doap: Let's say XEP-0368 support is complete now We break the SHOULD about the merged _xmpp and _xmpps SRV handling, but we follow all the MUSTs

util.prosodyctl.check: Fix A/AAAA check for proxy65 and http When there are no records to return the return value from dns.lookup() might be nil or might be a table containing zero records, depending on which DNS library is used

util.prosodyctl.check: Include multiplexed ports in DNS checks #1704

mod_admin_shell: Add descriptions of each column to 'help columns' Since some of the titles are quite dense

mod_admin_shell: Use exact match instead of Lua patterns in c2s,s2s:show It is unexpected that 'example.com' matches 'exampleicom.org' and this use of Lua patterns is undocumented and unlikely to be widely known or used.

mod_http_file_share: Use alternate syntax for filename in Content-Disposition The Lua string.format %q doesn't behave correctly for all characters that should be escaped in a quoted-string. And who knows what effects higher Unicode might have here. Applying percent-encoding of filenames seems like the safest way to deal with filenames, as well as being easier than implementing the actual quoted-string transform, which seems complicated and I'm not even sure it covers every possible character. Filenames can safely be assumed to be UTF-8 since they are passed in an attribute in the query without any escaping.

mod_admin_shell: Fix traceback on rendering graph of stats without extra labels Stops an error when extra_labels is nil since it attempts to index it Unsure about correctness

mod_admin_shell: Add help section about stats
