    - fix the macros for dealing with IVs
      + protect them with braces
      + make the deal with the length variable
      + convert loose memcpy calls into macro calls
      + eliminate a few redundant calls
    
    - eliminated unused st_old_iv from struct state
      and add better comments for the other iv fields
    
    - add a bit of explanation to the countinuation structures
    
    - eliminate .pcrc_free field from struct pluto_crypto_req_cont
    
    - prcr_init: ditched non-standard parens around braces around body
    
    - extend prcr_init to set the .pcrc_func field (better discipline, shorter code)
    
    - got rid of ike_continuations.h.  Its contents belong in pluto_crypt.h
