Add option to build ed25519 with Tinycrypt.

This depends on intel/tinycrypt#42 being accepted and update of local copy.

UPDATE: sha-512 was added separately while upstream PR is pending acceptance.

This needs to be rebased after #629 is merged for it to fail as would be expected.

A patch adding sha-512 to upstream tinycrypt was submitted:
intel/tinycrypt#42

While it is not accepted, add the code under a new ext/tinycrypt-sha512
depedency.

* Mynewt always uses sha-512 from tinycrypt
* Zephyr can choose either tinycrypt or mbedTLS

@d3zd3z To avoid stalling a new release, I updated this PR adding sha-512 for tinycrypt in another external included library. It is being tested on the sim, and I tested it on Mynewt and Zephyr.

LGTM. I agree about merging this, and then cleaning up once it is merged upstream.
