This patch untangles the interplay of the base library and the libc during the exit handling. - The CXA ABI for the atexit handling is now provided by the libc. For plain Genode components without libc dependency, __cxa_atexit is a no-op, which is consistent with Genode's notion of components. - The 'abort' implementation of the base library no longer calls 'genode_exit' but merely 'sleep_forever'. This way, the cxx library no longer depends on a 'genode_exit' implementation. - The libc provides 'atexit' support by storing metadata on the libc kernel's heap now, thereby eliminating the former bounded maximum number of atexit handlers. - Shared-library dtors are no longer called via the atexit mechanism by explicitly by the dynamic linker. This slightly changes the call order of destructors (adjustment of the ldso test). Functions marked as destructors are called after the atexit handlers now. - The libc executes atexit handlers in the application context, which supports the I/O operations in those handles, in particular the closing of file descriptors.
