* 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
