Log Message

* linux-nat.c (linux_child_follow_fork): If following the child,
and not detaching the parent, also add the child fork to the fork
list.
* linux-fork.c (linux_fork_context): Remove dead error call.
Assert that the incoming newfp argument is not null. Do not add a
new fork for inferior_ptid. Assert that there is one already.
