/*
 * Map an integer into a descriptive string.
 *
 * entry:
 *	buf - A buffer into which this routine can format
 *		a result string, if necessary.
 *	bufsize - sizeof(buf)
 *	val - The value for which a string is desired.
 *	flags - CONV_FMT_* values, used to influence formatting of
 *		the resulting string.
 *	num_msg - # of Msg entries in msg, msg_altdump, and msg_altfile.
 *	msg - Array of num_msg Msg items corresponding to the possible
 *		strings corresponding to val.
 *	msg_altdump - NULL, or array of num_msg Msg items, to be used
 *		instead of msg when the CONV_FMT_ALTDUMP flag is set.
 *	msg_altfile - NULL, or array of num_msg Msg items, to be used
 *		instead of msg when the CONV_FMT_ALTFILE flag is set.
 *
 * exit:
 *	If val lies in the range [0-(num_msg-1)], then the string
 *	corresponding to it is returned:
 *		1) If CONV_FMT_ALTDUMP is set and msg_altdump is non-NULL,
 *			the string comes from msg_altdump.
 *		2) If CONV_FMT_ALTFILE is set and msg_altfile is non-NULL,
 *			the string comes from msg_altfile.
 *		3) If neither of the previous rules holds, the string
 *			comes from msg.
 *	if val is outside the range, an ASCII representation of it is
 *	formatted into string, and that is returned.
 *
 * note:
 *	Ideally, this would be a function defined in globals.c.
 *	However, it uses the MSG_ORIG macro, which uses an array
 *	that is local to each module. Hence, this is a static function,
 *	defined by this macro. Once defined by a module, the routine
 *	is called normally.
