  NSPR I/O layer that terminates in a pair of circular buffers
  rather than talking to the real network.
  To use this with NSS:
  1) call memio_CreateIOLayer to create a fake NSPR socket
  2) call SSL_ImportFD to ssl-ify the socket
  3) Do your own networking calls to set up a TCP connection
  4) call memio_SetPeerName to tell NSS about the other end of the connection
  5) While at the same time doing plaintext nonblocking NSPR I/O as
     usual to the nspr file descriptor returned by SSL_ImportFD,
     your app must shuttle encrypted data between
     the real network and memio's network buffers.

     are the hooks you need to pump data into memio's input buffer,
     and memio_GetWriteParams/memio_PutWriteResult
     are the hooks you need to pump data out of memio's output buffer.
