BUG/MINOR: hlua: fix unsafe hlua_pusherror() usage
Following previous commit's logic: hlua_pusherror() is mainly used
from cleanup paths where the caller isn't protected against LJMPs.
Caller was tempted to think that the function was safe because func
prototype was lacking the __LJMP prefix.
Let's make the function really LJMP-safe by wrapping the sensitive calls
under lua_pcall().
This may be backported to all stable versions.
