/* Establish the initial context for the current lookahead if no initial
   context is currently established.

   We define a context as a snapshot of the parser stacks.  We define
   the initial context for a lookahead as the context in which the
   parser initially examines that lookahead in order to select a
   syntactic action.  Thus, if the lookahead eventually proves
   syntactically unacceptable (possibly in a later context reached via a
   series of reductions), the initial context can be used to determine
   the exact set of tokens that would be syntactically acceptable in the
   lookahead's place.  Moreover, it is the context after which any
   further semantic actions would be erroneous because they would be
   determined by a syntactically unacceptable token.

   YY_LAC_ESTABLISH should be invoked when a reduction is about to be
   performed in an inconsistent state (which, for the purposes of LAC,
   includes consistent states that don't know they're consistent because
   their default reductions have been disabled).  Iff there is a
   lookahead token, it should also be invoked before reporting a syntax
   error.  This latter case is for the sake of the debugging output.

   For parse.lac=full, the implementation of YY_LAC_ESTABLISH is as
   follows.  If no initial context is currently established for the
   current lookahead, then check if that lookahead can eventually be
   shifted if syntactic actions continue from the current context.
   Report a syntax error if it cannot.  */

       for details.  YYERROR is fine as it does not invoke this
       function.
     - If this state is a consistent state with a default action, then
       the only way this function was invoked is if the default action
       is an error action.  In that case, don't check for expected
       tokens because there are none.
     - The only way there can be no lookahead present (in yychar) is if
       this state is a consistent state with a default action.  Thus,
       detecting the absence of a lookahead is sufficient to determine
       that there is no unexpected or expected token to report.  In that
       case, just report a simple "syntax error".
     - Don't assume there isn't a lookahead just because this state is a
       consistent state with a default action.  There might have been a
       previous inconsistent state, consistent state with a non-default
       action, or user semantic action that manipulated yychar.
       In the first two cases, it might appear that the current syntax
       error should have been detected in the previous state when yy_lac
       was invoked.  However, at that time, there might have been a
       different syntax error that discarded a different initial context
       during error recovery, leaving behind the current lookahead.
