Fix syntax error on page protection flags check when determining whether we encountered a return address. Also limit the amount of dynamic memory allocation calls, offer a large enough static buffer where we can just write into when we crash without needing to alloc or realloc anything. Also removed some hacky code like the whitelist set, and made the module handle array static into the class as well. The CrashHandler singleton is now a static class instance.
