util.pposix,signal: Pass around various OS numbers as integers [Lua 5.3] Passing around PIDs, UIDs etc as integers makes it more sane in Lua 5.3. Getting 1234.0 as PID is silly. Shouldn't change any behavior as these are all integers on the C side and the integral floats are accepted as integers when passed back from Lua into C.

mod_admin_telnet: Use tostring as fallback in pretty printing This has some nice effects such as functions, VirtualHosts and other things being printed using their `__tostring` metamethod.

mod_admin_telnet: Don't pretty-print the normal console stuff Typing e.g. `c2s` would dump out a bunch of stuff that would probably just confuse users. Now you only get pretty-printing when poking around in the internals with `>`.

mod_admin_telnet: Reuse existing pretty printing setup Didn't do the configurable defaults thing here because I was going to do this, so that there's only one spot where it's done.

mod_admin_telnet: Allow configuring pretty printing defaults Mostly just to have the defaults merged so you can e.g. output:configure({maxdepth=1})

MUC: Enforce strict resourceprep when registering room nicknames If nickname enforcement is enabled this would otherwise let you bypass the join check in muc.lib by registering an invalid nickname and then joining with any nickname, letting register.lib change it to the invalid registered nick.

mod_storage_sql: Log database connection parameters when creating engine This is meant to help trace down an issue where Prosody apparently creates multiple conflicting SQL engines, causing problems especially with SQLite3, e.g. #616 #784.

mod_admin_telnet: Silence luacheck

mod_admin_telnet: Add a command to configure pretty-printing settings Sometimes you wanna adjust the maxdepth or something.

mod_admin_telnet: Add a TODO for someone to find in the future
