* linux-nat.c (linux_child_follow_fork): If we're staying attached
to the child process, enable event reporting on it. Don't handle
checkpoints here. Instead, add the child fork to the lwp thread
and inferior lists without clobbering the previous inferior. Let
the thread_db layer learn about a new child process, even if
following the parent.
(linux_nat_switch_fork): Delete lwps of the current inferior only,
instead of clearing the whole list. Use thread_change_ptid to
give the core the illusion the new checkpoint is still the same
inferior. Clear the register cache.

checkpointing, and use make_cleanup_restore_integer to restore it.
Don't reinsert breakpoints here.

not forks.
