lexer calls yylex_fatal on fatal internal errors. yylex_fatal itself is
declared as noreturn and calls exit. Returning from noreturn function has
unpredictable consequences.

	We have only 92K of stack and using over 4K per frame is wasteful

	* grub-core/script/yylex.l (yyalloc), (yyfree), (yyrealloc): Declare
	as macros so that compiler would remove useless structure on stack.
	Better solution would be to fix flex not to put this structure on
	the stack but flex is external program.
