Log Message:
Alter the protocol impemented by prop_kern to allow for bi-directional
plist-based messages and to eliminate looping previously required to
receive a plist from the kernel:

- prop_dictionary_copyin_ioctl() and prop_dictionary_copyout_ioctl()
  now take the cmd argument rather than the file open flag.  The
  read-ness or write-ness of an ioctl command is checked by these
  routines to ensure that information is being passed to/from the
  userland component properly.

- prop_dictionary_copyout_ioctl() now allocates the memory for the
  XML plist on behalf of the userland component by way of uvm_mmap().
  The XML plist is copied out to the newly-mapped anonymous region,
  and the pointer returned via the plistref.

- prop_dictionary_recv_ioctl() is responsible for munmap()'ing the
  region after parsing the XML plist into internal represenatation.

- A new prop_dictionary_sendrecv_ioctl() is added, allowing user space
  code to send a dictionary to the kernel and receive one back as a
  reply.

Update users of prop_kern for the API changes (Bluetooth).

This constitutes an ABI / protocol change -- but this will also be put
into NetBSD 4.0 so that the first proplib release will implement the new
scheme.
