  SVN rev 222408 on 2011-05-28 08:13:39Z by lstewart
  
  MFC r216758,217252:
  
  - Add some helper hook points to the TCP stack. The hooks allow Khelp modules to
    access inbound/outbound events and associated data for established TCP
    connections. The hooks only run if at least one hook function is registered
    for the hook point, ensuring the impact on the stack is effectively nil when
    no TCP Khelp modules are loaded. struct tcp_hhook_data is passed as contextual
    data to any registered Khelp module hook functions.
  
  - Add an OSD (Object Specific Data) pointer to struct tcpcb to allow Khelp
    modules to associate per-connection data with the TCP control block.
  
  - Tweak the MFCed code to preserve the ABI of the 8-STABLE branch with respect
    to "struct tcpcb" by consuming some of the padding within the struct.
  
  - Bump __FreeBSD_version to 802506.
