libxl: Rerun bison and flex
We are going to want to cherry pick a change to the bison input, which
will involve rerunning bison.
So firstly, update the bison and flex output to that from current
Debian wheezy (i386; 1:2.5.dfsg-2.1 and 2.5.35-10.1 respectively).
There should be no functional change since there is no change to the
source file, but we will inherit bugfixes and behavioural changes from
the new version of bison. So this is more a matter of hope than
knowledge.

+ for details. YYERROR is fine as it does not invoke this

+ - 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.
+ - Of course, the expected token list depends on states to have
+ correct lookahead information, and it depends on the parser not
+ to perform extra reductions after fetching a lookahead from the
+ scanner and before detecting a syntax error. Thus, state merging
+ (from LALR or IELR) and default reductions corrupt the expected
+ token list. However, the list is correct for canonical LR with
+ one exception: it will still contain any token that will not be
+ accepted due to an error action in a later state.
