qapi: Drop unused and useless parameters and variables
gen_sync_call()'s parameter indent is useless: gen_sync_call() uses it only as optional argument for push_indent() and pop_indent(), their default is four, and gen_sync_call()'s only caller passes four. Drop the parameter. gen_visitor_input_containers_decl()'s parameter obj is always "QOBJECT(args)". Use that, and drop the parameter. Drop unused parameters of gen_marshal_output(), gen_marshal_input_decl(), generate_visit_struct_body(), generate_visit_list(), generate_visit_enum(), generate_declaration(), generate_enum_declaration(), generate_decl_enum(). Drop unused variables in generate_event_enum_lookup(), generate_enum_lookup(), generate_visit_struct_fields(), check_event().
