This adds some magic addresses for use with PT_USERPEEK that allow gdb to find out where a process is located in memory, so it can correctly relocate its symbols to match the running process. The actual implementation in sys_ptrace is currently tangled up with some other ptrace changes, so I'll leave that for later.
