* Exposed SIDH through KEM API. * Removed old kex_sidh_msr refs * Removed kex_sidh_msr refs from Visual Studio project * Removed kex_sidh_msr from test_kex. * Added sidh alg sheet * Skip sidh in kat check (no kat files for sidh, unlike the related sike alg) * Added return values to sidh KEM methods (to fix wrong default return values on mac). * Addressed review comments on PR368. * Removed text_kex from Visual Studio; no more KEX built by default on Windows. * Removed test_kex from appveyor test. * Removed minimal_kex from appveyor

Summary
- Name: SIDH
- Algorithm type: key exchange
- Note: SIDH is as ephemeral KEX related to the SIKE KEM (sike.org) submitted to NIST
- Main cryptographic assumption: (supersingular) isogeny walk problem
- Submitters' website: https://github.com/Microsoft/PQCrypto-SIDH
- Added to liboqs by: Christian Paquin
