Log:
MFC: Close some races between procfs/ptrace and exit1() by changing
exit1() to block until any current PHOLD's are released. This includes
Simplifying the cleanup code in kern_ptrace() and removing the now
unnecessary vmspace ref counting magic from proc_rwmem(). Also, the
locking for ptrace_single_step(), ptrace_set_pc(), and
ptrace_clear_single_step() have been fixed to be consistent across the
tree.
