   Introduce packed data types for field and group elements, which are smaller, guaranteed to be normalized and non-infinite, and are comparable in memory.

   This speeds up signing around 1-2%, and verification around 0.1-0.2%, and reduces memory footprint.

2. Field storage type ff889f7d90
3. Add group element storage type e68d7208ec
4. Use group element storage type in EC multiplications 41f8455434
5. Switch ecmult_gen to use storage types 55422b6aaf
6. Remove the non-storage cmov fcc48c4561
