  Log:
  Prevent the rp driver from panic'ing on first access and make at
  least the pci device unloadable
  
  - Use ttymalloc() rather than a plain  malloc to allocate the
    rp->rp_tty ttys.  This is now required due to the recent locking
    changes to ttys and prevents a panic due to locking an unitialized
    t_mtx.
  
  - Allow the pci driver to be unloaded.  This involved moving
    the call rp_releaseresource() to the end of rp_pcireleaseresource(),
    since rp_pcireleaseresource() uses ctlp->dev, which is freed
    by rp_releaseresource().
  
  - Allow the generic part of the driver to be unattached by providing
    a hook to cancel timeouts.
