First go at format string checking for sscanf et al.
Added __handle_sscanf_format().
F_SSCANF-nodes are now type checked with new_check_call() (just like ordinary function calls).
new_check_call() now accepts and detects F_LVALUE_LIST nodes as arguments.
Added flag CALL_ARG_LVALUE to indicate that checked arguments are lvalues.
