HXCOMM Use DEFHEADING() to define headings in both help text and texi

HXCOMM Text between STEXI and ETEXI are copied to texi version and

HXCOMM discarded from C version

HXCOMM DEF(command, args, callback, arg_string, help) is used to construct

HXCOMM monitor commands

HXCOMM HXCOMM can be used for comments, discarded from both texi and C

Change the password associated with the VNC server. If the new password is not

supplied, the monitor will prompt for it to be entered. VNC passwords are only

significant up to 8 letters. eg
