syscall_emul: [PATCH 15/22] add clone/execve for threading and multiprocess simulations
Modifies the clone system call and adds execve system call. Requires allowing processes to steal thread contexts from other processes in the same system object and the ability to detach pieces of process state (such as MemState) to allow dynamic sharing.
