mod_admin_shell: Add muc:occupants(room) command to list occupants Easier than going trough muc:room():each_occupant() since you have to do fiddly things to reach the print() function.

util.startup: Close state on exit to ensure GC finalizers are called Ensures a last round of garbage collection and that finalizers are called. Fixes things like proper closing of SQLite3 state. There are more calls to os.exit() but most of them exit with an error or in a case where a final GC sweep might not matter as much. It would be nice if this was the default. Calling util.statup.exit() everywhere may be sensible, but would be more involved, requiring imports everywhere.

util.prosodyctl.shell: Close state on exit to fix saving shell history This ensures a last round of garbage collection and finalizers, which should include flushing the readline history file. Test procedure: ``` $ ./prosodyctl shell prosody> s2s:show() -- any command that is not the last in history ... output prosody> bye $ ./prosodyctl shell prosody> ^P ``` After this, the shell prompt should contain the last command from before the "bye". Before this patch, recent history is gone most of the time.

mod_mam,mod_muc_mam: Minimize differences (reorder, copy some comments) Should have no functional difference, but makes it easier keeping mod_mam and mod_muc_mam in sync.
