Refactor: wrap syscall.Wait4
...
Wrap syscall.Wait4 and cleanup a few coordination issues.
There are still some issues here where background threads are left
sleeping. This could potentially cause weird issues. There are a few
more things I have planned to cleanup thread coordination issues.

Optimize Next implementation
...
Once the program detects that we have stepped into another function,
we simply calculate the return address and then set a breakpoint and
continue to that location, avoiding numerous syscalls.

Now that I'm using the step strategy, I put in an optimization where if
stepping into another function, simply find the return address, put a
breakpoint there, and then continue.

* Setting correct breakpoint when returning from function
* All facilities are available for this, it just is not taken into
account in the current `next` implementation.
