If we use _`whatever`_ here in ejabberd man pages,
it is converted to *`whatever`* in markdown,
and docs.ejabberd.im/Makefile converts to the proper links
The default value for the 'max_fsm_queue' option was set to 10000 in
commit 79685da90b, and that value is still
documented to be the default. It was (probably unintentionally) changed
to 5000 in commit 03de853e4f.
It makes sense to keep it larger than the value of mod_stream_mgmt's
'max_ack_queue' option.
Several documentation callbacks (doc/0 and mod_doc/0) are implemented
and `ejabberdctl man` command is added to generate a man page. Note
that the command requires a2x to be installed (which is a part of
asciidoc package).
When module's options were updated (e.g. by reloading ejabberd.yml)
and, later, the module's process crashed, gen_mod supervisor
restarts the process with outdated options. This is now fixed.
