    pluto: improve modularity of hashing functions (as suggested by Andrew)
    
    - eliminate HMAC_*_BLOCKSIZE macros by manual substitution.
      These really aren't abstractions.
    
    - document lack of documentation for the correct bound for ckaid space
    
    - add passerts to check that MAX_HMAC_BLOCKSIZE is sufficient.
      New hash functions might make this manually configured value wrong.
