More Anti Debugging Checks.

I have successfully bypassed most of the anti-debugging checks mentioned in the provided sources while running in the Xcode debugger and under LLDB. However, I have not included a patch for the svc
stuff; it might be possible to implement some kind of pattern scan for that.
I also implemented a hook for the task_get_exception_ports
function and set *masksCnt
to 0, effectively bypassing its behavior.
btw for the ptrace
checks, they can still retrieve the function address from dlsym
, and it ignores the current hook you have implemented.
Syntax errors have been fixed in the code.
