    pluto: tidy frag handling
    
    - reverse sense of bool result of ikev2_check_fragment and ikev2_collect_fragment
      so that TRUE means success
    
    - fix send_or_resend_ike_msg's handling of two kinds of fragmentation
    
    - add comments to record hard won learnings
    
    - eliminate unused e_pbs parameter of ikev2_encrypt_msg
    
    - make more generous frag_buffer allocation in ikev2_record_fragment
    
    - start to separate v1 and v2 fragment size limits.  Not yet right.
    
    - still needed: separate bounds for size of packet that doesn't
      need fragmentation and size of fragment (for v1 and v2)
    
    - use child's state object after calls to ikev2_parent_inI2outR2_auth_tail
      (this is critical for emitting packets correctly)
    
    - sprinkle "const" where helpful
    
    - add passerts for certainty

    pluto: clarify ikev2_parent_inR1outI2_tail by transformation
    
    - move variable declarations so they can be initializing,
      even if that moves them into the middle of code
    
    - sprinkle const
    
    - split some multi-purpose variables
    
    - elminate redundant initializers
    
    - convert magic number 4 to NSIZEOF_isakmp_generic
    
    - eliminate braces for blocks with no local variables and
      no control flow implications
    
    - misc. tidying.
