Anna Zaks fe1eca5169 [analyzer] Assume escape is possible through system functions taking void* 
The analyzer assumes that system functions will not free memory or modify the
arguments in other ways, so we assume that arguments do not escape when
those are called. However, this may lead to false positive leak errors. For
example, in code like this where the pointers added to the rb_tree are freed
later on:

		struct alarm_event *e = calloc(1, sizeof(*e));
<snip>

		rb_tree_insert_node(&alarm_tree, e);

Add a heuristic to assume that calls to system functions taking void*
arguments allow for pointer escape.
