tracehook: clone
This moves all the ptrace initialization and tracing logic for task
creation into tracehook.h and ptrace.h inlines. It reorganizes the code
slightly, but should not change any behavior.
There are four tracehook entry points, at each important stage of task
creation. This keeps the interface from the core fork.c code fairly
clean, while supporting the complex setup required for ptrace or something
like it.
