Yawning Angel 840e68d917 Integrate and enable ed25519-donna.
The runtime sanity checking is slightly different from the optimized
basepoint stuff in that it uses a given implementation's self tests if
available, and checks if signing/verification works with a test vector
from the IETF EdDSA draft.

The unit tests include a new testcase that will fuzz donna against ref0,
including the blinding and curve25519 key conversion routines.  If this
is something that should be done at runtime (No?), the code can be
stolen from there.

Note: Integrating batch verification is not done yet.
