  o Minor feature (performance):
    - Improve the runtime speed of the ntor handshake by using an
      optimized curve25519 basepoint scalarmult implementation from the
      public-domain ed25519-donna by Andrew M. ("floodyberry"), based on
      ideas by Adam Langley. Implements ticket 9663.
Integrate the accelerated Curve25519 scalar basemult. Integration work scavanged from nickm's `ticket8897_9663_v2` branch, with minor modifications. Tor will still sanity check the output but now also attempts to catch extreme breakage by spot checking the optimized implementation vs known values from the NaCl documentation.
