The CPU session interfaces comes with the ability to install an exception handler per thread. This patch enhances the feature with the provision of a default signal handler that is used if no thread-specific handler is installed. The default signal handler can be set by specifying an invalid thread capability and a valid signal context capability. Furthermore, this patch relaxes the requirement of the order of the calls of 'exception_handler' and 'set_pager'. Originally, the exception handler could be installed not before setting a pager. Now, we remember the installed exception handler in the 'Cpu_thread' and propagate to to the platform thread at a later time.
This is generic part of the Genode implementation. It consists of two parts: :_Core_: is the ultimate root of the Genode application tree and provides abstractions for the lowest-level hardware resources such as RAM, ROM, CPU, and generic device access. All generic parts of Core can be found here - for system-specific implementations refer to the appropriate 'base-<system>' directory. :_Base libraries and protocols_: that are used by each Genode component to interact with other components. This is the glue that holds everything together.
