Add Dilithium (#172)
* fixes dynamic memory allocation test. previously a function called freeze() would trigger it

* this adds DilithiumII. Preprocessor conditionals still need to be removed

* fix ms Makefile

* fix MS compiler warnings

* clean-up

* remove preprocessor conditionals

* add dilithium3

* add dilithium4

* add duplicate consistency checks

* SHA2 state constants in common

* clean up symmetric.h

* Port SPHINCS+-SHA256 to sha256ctx struct

* Implement ctx struct for fips202

* Port Kyber{512,768,1024} to fips202 ctx struct

* Port NewHope to fips202 structs

* Port SPHINCS+-SHAKE256 to fips202 ctx structs

* Use opaque fips202 structs in MQDSS

* port dilithium to use fips202 ctx structs

* include -Wredundant-decls

* remove comment; format NTT constants

* reduce casts in power2round
