Message : rules: Require layout or variant to enable %i expansion Before this commit, the following rule would always match: ! model = symbols * = s:%i and set symbols to `s:1`, but the `:%i` is aimed to be used only when the rules header specifies the layout or the variant. Let’s be strict and disallow matching this kind of buggy rule. Emit an error message so that we can detect it.

/*
 * Macro sorcery: PREPEND_MESSAGE_ID enables the log functions to format messages
 * with the message ID only if the ID is not 0 (XKB_LOG_MESSAGE_NO_ID).
 * This avoid checking the ID value at run time.
 *
 * The trick resides in CHECK_ID:
 * • CHECK_ID(0) expands to:
 *   ‣ SECOND(MATCH0, WITH_ID, unused)
 *   ‣ SECOND(unused,WITHOUT_ID, WITH_ID, unused)
 *   ‣ WITHOUT_ID
 * • CHECK_ID(123) expands to:
 *   ‣ SECOND(MATCH123, WITH_ID, unused)
 *   ‣ WITH_ID
