Ozkan Sezer 1928f2e1b8 * first shot at cvar flag system and cvar layer clean-ups : 
- removed the archive and server members of cvar_t structure
  which are now represented by the CVAR_ARCHIVE, CVAR_NOTIFY
  and CVAR_SERVERINFO flags.
- added new Cvar_SetROM and Cvar_SetValueROM functions to 
  set vars marked as CVAR_ROM (read-only vars) programaticaly
- added Cvar_SetCallback() as a new function to assign (or
  remove) a callback function to a cvar.
- changed Cvar_RegisterVariable() to only accept a var pointer
  as in original quake
- moved notification handling from Cvar_Set() to callbacks.
- changed Cvar_Set() so that it doesn't reallocate the var's
  string buffer if nothing is changed, nor does it run the
  var's callback.
- changed the 'registered' and 'cmdline' cvars to be read-only
  so that the users can't change it using the console.  (and
  with 'registered' flagged as CVAR_ROM, the 'static_registered'
  thing is no longer required)
- added comment that sending cmdline upon CCREQ_RULE_INFO is
  evil...
- more to follow later.
