This patch moves the thread operations from the 'Cpu_session' to the 'Cpu_thread' interface. A noteworthy semantic change is the meaning of the former 'exception_handler' function, which used to define both, the default exception handler or a thread-specific signal handler. Now, the 'Cpu_session::exception_sigh' function defines the CPU-session-wide default handler whereas the 'Cpu_thread::exception_sigh' function defines the thread-specific one. To retain the ability to create 'Child' objects without invoking a capability, the child's initial thread must be created outside the 'Child::Process'. It is now represented by the 'Child::Initial_thread', which is passed as argument to the 'Child' constructor. Fixes #1939
