When the emulation stops with a hard exception it's very useful for debugging purposes to dump the current guest memory layout (for an example see /proc/self/maps) beside the CPU registers. The open_self_maps() function provides such a memory dump, but since it's located in the syscall.c file, various changes (add #includes, make this function externally visible, ...) are needed to be able to call it from the existing EXCP_DUMP() macro. This patch takes another approach by re-defining EXCP_DUMP() to call target_exception_dump(), which is in syscall.c, consolidates the log print functions and allows to add the call to dump the memory layout. Beside a reduced code footprint, this approach keeps the changes across the various callers minimal, and keeps EXCP_DUMP() highlighted as important macro/function.
