More constification cleanup

Started by fixing gcc warning:
iceauth.c:47:1: warning: initialization discards ‘const’ qualifier from
 pointer target type [enabled by default]
 static char *defcmds[] = { "source", "-", NULL };  /* default command */
 ^

and chasing down the rabbit hole of the functions the command line
arguments can be passed through, until we came out the other side
const clean.
